Who came here from researching coronavirus

I feel like this channel should be 'Crash Course: Public Health'.

Is this about vaccines that have been carefully developed or about vaccines developed in a rush to make money and approved for emergency use?

I don't care if this is considered extreme, if someone chooses have their child remain unvaccinated for NON-medical reasons and their child dies from a preventable illness, then that parent should be charged with negligent homicide. Fuck, I'd go so far as to say if anyone dies and can be traced back to you or your child being willingly unvaccinated. How quickly society forgets how horrible these diseases truly are.

Funny how I stumbled upon this video, in one of my college classes we are doing a debate regarding vaccines. My overall opinion is that vaccines should not be mandated for children since there are medical exemptions and religious reasons. Another part that is not taken in account is just the parent's personal reason, which I believe is very important. If a parent doesn't want to vaccinate their child, that is a chance that they're taking. Parents that get their kids vaccinated should not have to worry about the un-vaccinated kids, because they're vaccinated! Yes vaccination does decrease the chance of spreading disease, which is great! But parental autonomy should be a big factor when choosing what to do to THEIR child!

I just got in an argument with someone online who is just flat out denying herd immunity.

I don’t understand how allowing the second kid with measles going to school puts everyone at risk if everyone is vaccinated?

Very good video. May I be somewhat selfish and make a request for a video about the MMR/autism disinformation? Seems like a logical followup given how this decreased takeups of the vaccination.

One of my favorite episodes of Law and Order: SVU was about how some parent didn't have their kid get their shots.

The hell are you bouncing around all over the place for?

Worst side effects I've gotten was from a collection of three vaccines: hepatitis a, HPV9 strain, and whooping cough. I got shoulder pain and minor swelling for two days

Would you consider doing a video on antidepressants and pregnancy? I know it's a small niche but it would be very helpful.

unless there is a medical reason for a child to be unvaccinated, i see no reason to allow children who are unvaccinated for NON MEDICAL reasons to attend public schools with children who DO have VALID MEDICAL reasons for not getting vaccinated and putting them in danger outbreak or not.

I like how he said that if a non-vac kid went to school and somehow got measles, it puts everyone else at risk. How would that child put everyone at risk if the vast majority of kids at school get vaccinated? So basically your at risk even if your vaccinated? Lol

I'm a student studying Public Health in Australia. I find it interesting when i'm reading international articles how definitions of Primary, Secondary and Tertiary healthcare differ between borders. I would really like to see a video on how your team defines these types of healthcare. Also, you should make a video on health care in Australia :)

Vaccines should be mandatory. I understand that freedom of choice is very important and valuable. But there are limits to freedom of choice. If i like eating candy i should be free to do so. But if i like eating other people i should not. So think about it: Getting vaccinated: Strengthens your immune system, helps the entire community stay healthy Not getting vaccinated: More risk to yourself, more risk to the entire community Choice like these that are so obvious should not be open to debate (apart from people with allergic reactions or valid medical reasons of course). But personal opinion, lack of education or religion simply shouldn't give an individual the right to "choose" to endanger others.

2:51 -- Not one kid under the age of one died from varicella from 2004 - 2007. What about before that? After that? This video was made (or published) in 2014. That's only a 3 year span. The numbers and stats seem a little sliced and diced... The numbers would have more significance if they painted a comprehensive picture...

Healthcare Triage those last two sentences were powerful writing. Thumbs up, writers!

If you've ever been in an oncology ward (hopefully you haven't), the first thing you'd notice is the big sign out front saying "Don't come in if you're sick or have been recently vaccinated", because everyone knows full well that certain vaccines shed for up to a year out of the nose, mouth and waste products. The smallpox and polio disappearance is also very misunderstood, and people unfortunately have the knee jerk reaction of celebrating vaccines as the reason they're by and large gone. Look closely and you'll notice certain truths that will make you scratch your head, and think twice. Here we go: Prior to 1954 (when the Salk vaccine was introduced) the criterion to diagnose polio was "partial or complete paralysis of one or more muscle groups, detected on two examinations at least 24 hours apart" (Dr. Bernard Greenberg). That's it. Laboratory confirmation and presence of residual paralysis was not taken into account. In 1955, paralytic cases continued to climb, and in fact kept climbing steadily into the early 60s. In order to align medical data with the desired appearance of success from the vaccine, the criterion of diagnosing polio changed. Two examinations 60 DAYS apart were required in order for a case to be recognized as polio, and of course reported polio cases plummeted, just because the criterion of diagnosing polio had changed. Prior to the introduction of the Salk vaccine, anything from lead poisoning to Guillain-Barré syndrome was reported as polio. (Incidentally, FDR didn't have polio. He had Guillain-Barré syndrome.) Paralytic polio was already on the decline, without the vaccine. All the vaccine did was keep it around longer than it would have been (look up the Cutter incident), and the same goes for Smallpox. Ask yourself, what about the diseases that have largely disappeared without a vaccine to credit? Scarlet Fever? The Bubonic Plague? Cholera? Why would we be so quick to credit the decline of polio and smallpox cases to a vaccine? Because it was there. This blind faith in a vaccine paved the way for the horror of the next 60 years and counting, and for the attack on everything healthy and good in our immune systems. Diseases (like measles and pertussis) are not on the rise because of the unvaccinated. I argue they are on the rise because of the VACCINATED. Like I said before, vaccines do not last forever (most last about 8 to 10 years if that depending on the individual and the vaccination), and therefore can not and will not ever contribute to herd immunity. If your last, say, measles booster was when you were 5 years old, and you're over 15 or 20 years old, you have no protection anymore, you are technically unvaccinated. Think of all the people walking around without protection. The CDC claims herd immunity requires 95% of a population to receive vaccinations to achieve it. 95% of people need to have active immunity to a disease. Never. That will never happen with vaccines. The only way to achieve true herd immunity is to catch the wild disease naturally. When that happens, you have immunity for life, not 8 to 10 years. It's all a complete lie, and a disgraceful farce. Also, the overuse of vaccines, like antibiotics, are causing these diseases to actually morph into new and "improved" versions of themselves. A pertussis strain was discovered to have mutated and now emits three times the amount of toxins (making it three times as harmful), than the pertussis the vaccine is designed to protect against. Nature will 100% of the time outsmart us. We have to understand something very basic. The pathogen does not determine how, when or if we get sick. Our bodies do. We need healthy immune systems to fight off the pathogens that could make us sick. Vaccines shatter our immune systems. They are inflammatory nonsense, and are systematically making us as a species weaker.

Parents can choose not to vaccinate, but they then choose to provide their children with their own education as they should be required to vaccinate to enter the public school system. It protects public health and private rights.

Fun fact: last time I was vaccinated, I couldn't walk for a few days.

Some vaccines also have egg bases or something, and those allergic to eggs might have an allergic reaction if given the vaccine.

This is often a topic of heated debates. When asked why people choose not to vaccinate their children there are often many reasons stated, but the overwhelming sentiment is often that they are doing what they feel is in the best interest for their child. In other words they are upholding their parental duty to protect their own child. The information that they are using to base this choice may or may not be valid, but the intent is admirable. The government and the schools have a duty to the whole population. The benefits far outweigh the risks when looked at as a whole and individual risks are rare. This video describes how herd immunity protects those that are immunized along with those in the population that are not eligible, such as babies too young for immunizations. When more and more parents opt out of immunizations for reasons other than allergies and strong religious convictions, they are relying on the benefits at are being provided by all of the parents that do immunize. That is a double standard. This opinion states “I want what I feel is best for my child by avoiding what I don’t feel is safe, but I also want the benefits from that same action when it is performed by other parents”. By not vaccinating these parents are reducing the herd immunity that has benefited our population for over a generation. Maybe that is part of the problem. These vaccinations are for diseases that parents never see anymore, and the generations that have experienced them are oftentimes no longer with us. I myself have vaccinated my children and believe that not only is it an act of the greater good, but it is in the best interest of my own children. It is my duty.

Talk about how vaccines don't last forever (more likely 5 to 8 years depending on the vaccine and the individual). Assuming vaccine protection lasts forever is the base of the herd immunity argument. Even if you were fully vaccinated as a kid, at the very latest, by 25 years old it's guaranteed any protection you may have had (may have had) has worn off. I was fully vaccinated as a kid. My last MMR booster was when I was 5. I had my titers drawn when I was pregnant to check on my rubella status, since that's problematic during pregnancy. I did not have measles or mumps immunity, not one bit, but I had rubella immunity because.... I got wild rubella (meaning not from a syringe, got the disease from the "wild", the "world") when I was a kid. If you get a disease naturally (like rubella or the measles or the chicken pox), you're immune for life. If you get a vaccine for that disease, all it does is postpone the next time you're unprotected again. What are we supposed to do? Get a booster for every disease they're marketing for now every 5 years? I can't think of a more lucrative business plan for the drug pushers. It's genius. Take the population's ability to protect itself away, and then force them into a lifelong vaccine program that will only make us sicker and sicker. So, to summarize, unless you've had every vaccine booster in the last 5 or ten years, you're unvaccinated! How many people do you know have received boosters for all 18+ diseases they've put on the schedule now? The vast majority of the population is unvaccinated. This is why so-called herd immunity is a farce. It's a big lie, and they know it. They just hope we don't catch on. A person is smart, but people are dumber than sheep, and if we continue to follow the herd, we'll lose everything, our health and our sovereignty.

In regards to vaccines, herd immunity is one of the most important things. A disease cannot spread if there are many people that have a vaccine. From a utilitarian perspective, I feel like it is for the greater good of the greater amount of people if everyone that can gets vaccinated. The more people that are vaccinated, the better. It can also be tied back to the moral theory of beneficence. As a society, we have a general obligation towards each other. We, for the most part, want to prevent spreading harm (disease) to those around us. What better way to do this than by getting vaccinated? There is little harm or risk associated with vaccines. Sure, you might get a slight fever, but that’s usually it. Vaccine aren’t perfect by any means, but by getting vaccinated we can build up herd immunity. It is safer for everyone to do this, including small babies and the immunocompromised. You wouldn’t walk up to a cancer patient and sneeze all over them, would you? Then why would you want to expose them to a vaccine preventable illness?

Why are many videos starting to show up on YT with a yellow/green tinge on the video, vlogbrothers, crash course, etc. most others are fine, just a subset. It's this due to YT encoding or a camera type, or a non-standard gamma? It's not my monitor as I can switch between "proper" gamma and these off-color vids so it's not a local problem.

The fact that less people are infected with diseases is not only due to vaccines but also to the fact that we live in a very healthy and protected environment in the Western world with very few areas that give infections a chance to spread. So I wonder how many people would actually get infected with one of these diseases if there weren't any vaccines at all.

just dropin by to learn more on what herd immunity is had a vague idea but never knew for sure thank you

The lack or heard immunity is also a big reason why we have so many computer viruses and spam. Quite interesting how human technology can mimic nature.

I feel this video could have been much longer. I agree with the issue at hand, but am not sure where to find more trustworthy and understandable information.

Great video. The only part I disliked was the 30 second unskippable ad in the beginning for an R-Rated movie. Don't get me wrong, I understand that ads are necessary, but if they are going to be on such violent topics, it needs to have a skip button.

There's something I'm not understanding here... Why are vaccinated kids in danger from unvaccinated kids? What's the point of a vaccination if you're still vulnerable to the disease? And if vaccinated people can get sick, what's to say they wouldn't spread it to other vaccinated people as well as unvaccinated people?

I also believe that vaccines are not perfect, but they are necessary and should be incorporated as much as possible. Vaccinating more of the population will prevent outbreaks of certain diseases. However, a vaccination cannot be undone, but someone can always get vaccinated later once they are more informed about the possible risks or consequences they might face if they are vaccinated. It is also important that they know what is being put into their body or their child's body before they are forced to get the vaccine.

Healthcare Triage needs to do a video on the misconceptions and/or an explanation on Ebola. When CNN is terrifying my fellow dead colleagues (Augustus has barricaded himself in his Mausoleum), something must be done. This video touches on the concept of outbreaks, but it is a bit generalized. A video overview of the disease and how it spreads, how it can be treated, and why it is not going to cause mass extinction would be wonderful.

Excellent video! Everybody needs to get this message.

I came here to find a video to help give a visual to my family who don't understand how herd immunity works.

I never knew about this as a health care provider. This is something I'm going to have to pass on to my fellow medics.

Your right; Herd Immunity only works when almost everyone is vaccinated. So as long as "public health" continue to promote vaccinations to the 85ers (85% of the population) and it continues to be successful than my children should be fine without being vaccinated. The measles of the unvaccinated child was unfortunate I don't think their parents were to blame. We all are trying to do the best thing for our children. Great video though.

Awesome video! Thanks, Dr. Carroll. I also recently watched your videos on NNT (number needed to treat) and NNH (number needed to harm) videos. I think everybody needs to watch this video and those two! Your NNT and NNH videos made me understand how some *doctors* have made videos suggesting that the risks of the MMR vaccine are greater than the benefits. After watching your NNT&NNH videos, I realize those statements may actually, *technically* be true: The risk of a vaccine giving somebody, say, a mild fever for a day, or soreness at the injection site, probably *are* greater than the chances of contracting measles. (Those are not equal risks, mind you; I’d much prefer to have soreness at an injection site than measles!) But *why* are the chances of (much lesser) harm, possibly, higher than the chances of avoiding the (much more-dangerous) disease? Because most people *are* still doing the right thing for their communities and themselves and *are* getting their kids vaccinated on schedule! These questionable doctors’ *may* technically be quoting the stats correctly, but if so, those stats are only as they say because most *others* are doing the *right* thing, and those doctors are asking them to *compromise* those stats!

This video does a wonderful job explaining why it is so important to vaccinate your children unless it is medically necessary that you do not. When too many people start assuming they do not need to vaccinate because "other people are vaccinated", this causes an extreme breakdown for herd immunity. We need herd immunity for those who cannot be vaccinated, such as young babies, the elderly, and the immune-compromised. When you choose not to vaccinate yourself or your child for reasons that are not medically related, you put yourself, your child, and someone else at risk for disease. I am a mother of 3 and all of my children have always been up to date on all vaccines. Although it is nice to have herd immunity, especially when my children were too young for said vaccines, we do not rely solely on herd immunity. Herd immunity is so important in keeping public health stable. I think that it is unfair and selfish for parents to not vaccinate their children when there is no medical evidence that it will compromise that child. Herd immunity only works when we vaccinate!

How does the school/government find out the kid is sick with that specific illness? They can't go into the pediatrician's files can they? What's really stopping a sick child from being sent to school, or withheld and their sibling being sent to school if the school never finds out?

Public and private schools should not be allowing students to attend school unless they are fully vaccinated. This goes for religious and any other reasons. The only way that a child should be allowed to not be vaccinated is if they have a very important medical reason and vaccinations would put them in danger. This is when herd immunity becomes so important. Healthcare Triage does a great idea of explaining this idea of 'herd immunity'. Before I began to do research on the vaccine movement I had never heard or understood this. If more parents who didn't vaccinate got informed on how not giving their healthy child a vaccine, they may change there mind. Every parent has the right to protect their own child but it doesn't give them the right to put someone else's child in danger. Herd immunity needs to be something that is explained to parents before they decide to put their children in school.

All children who are able to be vaccinated without definite side effects or future problems should be. The choice of a parent not to vaccinate a healthy child could end up making a child sick who was unable to receive a vaccination. Parents need to realize that in the big picture it is about protecting all children. If I was a parent I couldn't imagine the feeling knowing that my child got sick and spread it to others who were unable to be vaccinated due to medical reasons because of my decision. Not only would my child be sick, it would also harm other children who's parents really didn't have a choice in the first place.

I like the perspective on herd immunity in this video. I believe getting vaccinated is crucial to protect ourselves and others. As the video mentioned, vaccines aren't perfect; however, think of all of the people who have been vaccinated and have been completely fine. Herd immunity is about looking out for everyone, especially the vulnerable babies who are too young for vaccinations. We're doing ourselves and the community a favor by reducing the risk of having a serious outbreak.

Can you please explain how vaccination can help achieve herd immunity given the fact that even fully vaccinated people can still catch and pass on the virus ? Surely herd immunity is only possible when people become immune after vaccination or natural infection. If vaccinated people can still transmit the virus then how is vaccine mediated herd immunity possible ?

Could you talk about the follow-up vaccines? The varicella vaccine has to be re administered every few years. What implications would not getting the vaccine renewed be?

LOVE this video. I have learned so much from your videos. Keep up the great work with your channel!

I don't understand this nonsense of parents having certain rights over children. In Canada (ontario) parents have the rights over children's religious upbringing/education, and medical choices. This doesn't seem rational at all. The first case is simply a matter of preference, why should a parent's preference dictate the preference of another person? I knew a kid who was forced to attend church, even though they felt a stronger calling to islam, and was sent to a catholic school against his preference. Its absurd, and don't bring up "they feed, and clothe you", they made the choice to bring a sentient being into the world. The choice should clearly be up to the child. The other two should be the right/responsibility of the state. The state would have first-hand access to data and experts that would allow them to make far better informed choices than, often uninformed, parents.

The fact that herd immunity protects the non-vaccinated does not contribute to concluding that, vice-versa, non-vaccinated people pose a significant risk to those who are vaccinated in numbers great enough to provide herd immunity. In fact, risk groups such as the elderly and babies are generally not considered a threat to those who are vaccinated, so why would people not vaccinated for other reasons suddenly be considered such a great risk? Unless the amount of non-vaccinated people is so great that herd immunity does in fact break down, how big is the risk really when a sick person comes into contact with people who are vaccinated against the disease that person carries? Aside from the argument that 'vaccinations aren't perfect' no actual numbers are given on how big the risk really is, and I have a very hard time finding any data on this. More people possibly carrying a disease due to not being vaccinated against it (despite heard immunity), and thereby increasing exposure of vaccinated people to that disease by some amount, would seem to increase the risk of someone who is vaccinated catching that disease in the case where their immunity-by-vaccination fails, but by how much? Are these numbers even at all significant? How effective are vaccines in preventing a disease when someone is actually directly exposed to that disease? How prone to failure are vaccines and how likely is a marginal increase in exposure to preventable diseases to incur illness in a vaccinated population with herd immunity? What percentage of people would have to be vaccinated for herd immunity to exist, and at the same time for non-vaccinated people to impose a significant risk for the vaccinated population (if that is not already a contradiction)?

Please do a video on the Ebola virus and how worried should be. We need clarity.

Make an updated comment here about the Corona Virus Pandemic!

How long does the chicken pox vaccine last for? 10 years maybe? Does everyone get 10 year boosters on their chicken pox vaccine? I heard it was more like 50% max.....so how can you claim herd immunity?

Do vaccines help to lower the viral load within a vaccinated body?

Has it ever occurred to you that.....CORRELATION DOES NOT EQUAL CAUSATION??

Next video "Healthcare in Switzerland"?? Wow I was just about to request exactly that video.

This is a good topic to debate, vaccines and herd immunity. I personally do not think that vaccines should be required for children since there are medical exemptions and religious reasons. If a parent doesn't want to vaccinate their child, that’s the chance they're willing to take. Parents that get their kids vaccinated should not have to worry about the unvaccinated kids, because they're vaccinated! Yes, vaccinations do decrease the chance of spreading disease, which is great. But parental autonomy should be a big factor when choosing what to do to their child. The video did explain that herd immunity is beneficial, meaning that if a large number of kids get vaccinated then it theoretically helps the unvaccinated. That is an interesting concept to grasp.

I don't believe this for a minute.

Having had mumps, chicken pox, and measles as a child, I cannot understand why these anti-vaxers exist. In hindsight, I'm glad when many vaccines came out in the 70s like for rubella, etc. Do anti-vaxers exist because they have been so far removed from the bad times when we got quarantined, had to stay still (as a 7 year old that was tough), got scars (still have that dot on my nose), and may have gotten worse. Is it because the U.S. is getting so anti-Scientific wishing to go to ineffective potions and faith healers, believing in magic and a 6000 year old earth?

I completely agree that we need to get everyone vaccinated that it is possible to do but I do not agree with the people who say this should be done by state coercion. No one, no matter if they are acting on behalf of the state or not, should ever be forced to have anything injected into their bodies or undergo any medical procedure. I mean. What're they gunna do? Round people up and medicate them at gunpoint? No. We need to convince people. General scientific literacy is on the up. We will get there without fascism.

Honest question and i don't have any kids but interested in the topic: Recent whooping cough outbreak here in my area, when listing the cases they also report who in the group was/wasn't up to date on their vaccinations 85-90% of those affected with the pertussis were completely up to date and vaccinated! What's the advantage of getting vaccinated if you're just as (more?) likely to get sick even if you are fully vaccinated? How is this explained? I imagine that the 10-15% unvaccinated and infected portion isn't a higher porportion than the total unvaccinated population of the area.

I believe that it is the parents choice on whether or not their child is vaccinated, aka parental autonomy. I also believe that by not vaccinating your child, you are putting your own child at risk, along with other non-vaccinated children. I wouldn't think that vaccinated children would be at much of a risk, would they? But the biggest issue with not vaccinating children that have the ability to be vaccinated gives an unfair amount of risk to children that cant be vaccinated due to medical reasons. It would seem that herd immunity is great enough to allow those that refuse to vaccinate to do so, since putting their children at risk is their choice, right?

You should make a video about how states have and can react to Obamacare. I hear things about states not expanding Medicaid and the like, but I don't know what their true effects are.

While I agree that there is an insane amount of helpfulness that vaccines provide, they may just be one of the, if not the, best things invented in recent history. That being said, I still believe that people should be given a choice about whether or not they wish to vaccinate their kids. While some parents will refuse to vaccinate their kids because of the myth that vaccines cause autism, some parents do not vaccinate their kids because it does go against their personal and/or religious views. And with that, it brings up the question of schools. If a parent refuses to vaccinate their children for personal and/or religious views, that’s their choice. But that should not stop them from getting the same education as everyone else in the world (or at least in the United States). Private schools are notoriously picky about who they accept in. Not everyone has the money to attend private schools, and public schools should not (and are not allowed to) discriminate against students for any reason. Even if their parents made the decision to not vaccinate their kids, their kids should still be allowed into the public school no matter what. Even if it is during the time of an outbreak, if the school is public, it should still allow the student to enter the school. Either this or provide an alternate way for the student to still get the information that is being taught in the classroom at that time. Again, I am not saying that people should not be vaccinate. I was vaccinated as a kid, the only one I didn’t get right away was the HPV shot (but I am getting that now). However, there does get a point where children who were not vaccinate should not be discriminated against in public schooling. It is not the children’s faults, it is their parents’ faults. Do not deprive these children of an education because their parents chose not to vaccinate them. The children would not have had a say in whether or not they received the vaccine. These children still deserve an education, and public school is usually the first choice for those too poor to enroll in private schools.

Very informative. Thank you

4 people support the use of measles blankets.

The sources aren't properly linked. I can't find the study in the link.

I believe this is a great video and timely just. Herd immunity has seen a slight decrease in the recent years due to parents deciding not to vaccinate there children. I believe parents who do not vaccinate there children are selfish. They are not only putting their children at risk, but they are putting you and me at risk. Not only are the people that are vaccinated at risk but think about the children who are to young to be vaccinated or the older population that is not vaccinated they are put at even a higher chance of contracting a disease if your child is infected and spreads it to them. I just feel as if the parents that decide not to vaccinate don't think about what they are really doing or they just don't care about others. I 100% back the governments reasoning on backing schools to not admit children who are not vaccinated or are sick with a disease that could possibly cause a outbreak. I believe you should have to be vaccinated to attend a public school no matter ones personal belief.

Can you go "to the research" on the recent announcement about how taking an aspirin a day for a decade can lower risks of some cancers? The first mention on NBC shared no numbers whatsoever. And when I tried researching it myself, I never found percentages that agreed with other sources.

okay but what do you guys think about a vaccine that is NEW and may have potential side effects that could surface in a few years? That is the only thing stopping me.

Please add Annotations/Links in the video for the other videos in the end

Why does he keep jumping seats?

Getting vacinated doesn't mean you wont get the illness. My cousins kids both were vacinated for chickenpox and both got chickenpox!! When my cousin asked the doctor he said it was very common!!!!

Dr. Carroll, I have a question for you. If someone were naturally immune to a disease, e.g. the flu, would it help prevent others from getting the flu even if this person has never had the flu and never will?

Not vaccinating your child should be viewed as an act of child endangerment and medical neglect.

Dogs and cats are required to get rabies shots, kennel cough shots, among others, so shouldn't people be too? I love animals and have 2 dogs myself but shouldn't we put these laws in for people, since humans are of a bit more concern to the government than animals?

Excellent video as usual. THanks.

Before the usual crazy squad arrives I would just like to add that one of the problems I don't often see addressed is that there are often a lot of people working in the medical field who refuse to get vaccinated against anything they are not required by law. I think there is still much to be done in educating those who should actually know better : /

What is this video actually about? I need it for my presentation 😭

Very interesting, a side to vaccination that has never crossed my mind. Great video. Just to let you know though, while the 'Healthcare in Blank' videos are nice once in a while, I think this channel should inform us more on the Health itself. I'll watch the Switzerland video, but I'd prefer another like this.

What about natural herd immunity from normal exposure? Interesting how the WHO has changed the definition of herd immunity very recently. Fact.

Could someone help to clarify this for me? This video seems to back the following with logic and reasoning: People with compromised immune systems and those who cannot get immunized such as people of a certain age (too old or too young to be vaccinated) or possibly pregnant women or those with compromised immune systems are at risk when someone does not get vaccinated. And in this way, when outbreaks occur, individuals who are not vaccinated/immunized are put at risk. Then, at the the 4:15 mark, he says that people who refuse to vaccinate themselves aren't just putting themselves/children at increased risk, but also everyone else (which would include people who are vaccinated). However, all of the logic he presented up until this point in the video doesn't support that claim. Rather, all of the logic up to this point supports only the claim that people who aren't vaccinated are putting others who aren't vaccinated at risk. So, where is the evidence that people who ARE vaccinated, are being put at risk by those who are not? I am left to guess as to why that might be, because he didn't provide any supporting reason/evidence to back that claim. What I would guess is: 1) Because vaccines are not perfect, even those who are vaccinated might still catch the disease they were vaccinated against. Other than the herd immunity argument, are there other reasons for why vaccines sometimes don't work? My next guess might be one such reason, but I'm interested to learn more... 2) Because diseases can mutate into something that a vaccination isn't equipped to prevent, therefor when disease is able to spread to those who are not immunized, that makes for an environment where the disease is more likely to mutate. Thank you in advance for your time and input.

If you explained the strategy without the corresponding data I wouldn't buy into vaccinations. The numbers don't lie.

typo with the word significantly

Interesting side question. Should not vaccinating your children be open to prosecution as child abuse/neglect?

The official statement on Herd Immunity brought to you by The Pharmaceutical Companies!

Can't have herd immunity if everyone is at home.

I was vaccinated as a child for common illnesses yet I still got chicken pox and measles. The vaccinations do not prevent infection. The only period in my life that I got the flu for instance was when I was being forced as a child to take the flu vaccines. I would get ill like clockwork every year around the same time. I stopped taking them as an adult. I have only gotten truly sick a few time in the 25 years since I was no longer required to take a vaccination.

Maybe the government should make it compulsory for a child to be vaccinated before they can attend a public school.. Also, you should make a video about health related aspects vegetarian or vegan diets, or even paleo. Are there any actual benefits, and do they outweigh the negatives?

Hi safs class I’m Henry

I love it when people say "correlation is not causation" lol. Yes it does when it happens thousands of times.

This needs to be updated a bit

2:37 - 3:04 Babies less than 1 year old didn't die from the disease even though they're weren't vaccinated. Reason he gives? Because vaccines work. ??????

Thank you

man if see all these stray dogs walkin through my town, no vaccinations.... NONe HOW DO THEY DO IT?

Question on the chicken pox vaccine - I just had one person tell me that more adults are getting shingles because they aren't being exposed to chicken pox because their kids have been vaccinated (not giving the adults the "immunity boost"). This sounds extremely fishy to me. Any evidence for this? I did see one study claiming this, but also found a few points against the study, as you would expect.

Thanks for the video. I'd also add that it's important to keep your vaccinations updated - some of them wear off after a period of time, after which you need to get the shots again.

Thank you for a great video.

Thanks for making this. Very informative. 👍🏽 People should not fear vaccinations. Diseases should fear vaccinations!!

Why can't we give varicella vaccines to babies?

opens ur mind about outbreaks
