About :

Fewer children in the United States are getting vaccinated. That’s bad news for those kids, and also for public health in general. Often, the response is to argue and debate and get angry at people who are we see as making terrible, irrational decisions. Instead of doing that, let’s use science to understand why this is happening in the first place.

Yeah I was never vaccined primarily because they never really told me what it was for and what ingredients were in. So I never got my hands on any declaration form though I have no issue with it and I don't think it causes autism.

Your projected audience are those who have doubt about vaccines, they'll stumble across this video and look no further due to their lack of knowledge on the topic but will accept this load of crap you've presented as truth. Shame on you! It is clear that you are not a father, no parent, responsible loving parent that is...would ever research into vaccines and say what you're saying, worse, make a video telling tall tales as such. Clearly you profit in some way or another from big Pharma. May God have mercy upon your soul come judgement day.

I'm not vaccinated, because I ended up in the ER as an infant due to high fever and illness as a result of my 1st series of vaccines. To start every school year i had to bring medical records showing i wasn't a risk. I had amazing health until I had the Gardisil vaccine at 15. Within a short period of time I became very sick, my C Reactive protein was through the roof and i was soon diagnosed with Hashimotos Thyroiditis. I am a 1st hand example of how these vaccines can be harmful for some. Just because you're okay doesnt mean they're right for everyone. Stop fearing people that arent vaccinated, simply make your own choice.

I actually wish it would address issues other than autism. I myself don’t believe the autism link but I do worry about combos given to babies and would like clear answers on that side of things. Why give so many at once and why can’t I opt to have them given separately? What’s the harm in that request?

As someone diagnosed with High-Functioning Autism, I find the whole anti-vaccination movement insulting. I feel like it’s saying it better to die than be different than everyone else.

I don’t feel like I need to be cured, or believe that vaccines have anything to do with it. My autism doesn’t define who I am, and no child should ever feel like it makes them a lesser person for it.

So you can appreciate this videos attempt at an scientific non bias analysis of the issue. Though you can also recognize his bias approach to the issue. Basically saying that any people who question are misinformed and trust the experts who have done the science. I am also a scientist and one of the most fundamental understanding of science is that it can be wrong and has been many times. Science has rewritten itself on many topics countless times we all know that. Why would a scientist behave as if he doesn't understand that is questionable to me. Vaccines in no way have been proven to be completely safe by anyone. If that were so Congress would not have needed to pass a law giving Vaccine Companies immunity from prosecution for injuries caused by vaccines even death, total immunity. Things like the Vaccine Injury Compensation Program wouldn't exist. Things like VAERS wouldnt exist. And that had paided millions in compensation to victims many millions actually. And really just look at this comment section. Completely full of derogatory comments towards people who question if vaccines are completely safe. The ignorance is appaling because the truth is they aren't completely safe and many people have been harmed by vaccines if they bothered to look into the topic. People saying I'd rather have autism than be dead. Or Id rather have this disease or that than be dead. Is an gross oversimplification of the issue. Do you really believe if you go unvaccinated it is guaranteed death or disease??? Or if you get vaccinated you won't face death or disease?? There is an difference between vaccination and immunization. Have you bothered to look up the efficacy rates of these vaccines? I must say the Pro Vaccine group is just a full of ignorant people as they claim the "anti vaxxers" group is. Its very....strange to me that people who question the safety of chemicals in untested combinations being put into themselves and their children are being painted as these bad ignorant people who even have a derogatory name now "antivaxxer". While people who doesn't question the safety at all and blindy follow what the "experts" say without any sort of need to verify thier credentials or reasearch just assume everything an " expert" says is the unaltered truth and has your best interests in mind are being painted as some sort of wise well informed "good people".

I think the definition of autism has gotten broader. I think that autism caused by vaccines is just a conspiracy theory. I've heard theories that some vaccines give you the virus that it's trying to protect you from. Makes sense, but vaccines give you proteins that mimic those of the virus. At least I've read that at a vaccine website.

This rant has nothing to do with science. It is a rationalization that ignores quite a lot of the recent science on vaccines.Hank is starting to sound like a shill for pharmaceutical companies that make billions on vaccines. I am all for safe immunization, but not all vaccines are safe. Do your own research and don't settle for "a doctor said so." Doctors have biases, too. Ask for the scientific studies that show vaccines to be safe. They are not available because the CDC does not require them. Vaccination can and should be a public health success story, but there are real problems that need to be discussed and solved. Read your vaccine inserts. They actually tell you the risks, because they are required to. I used to like this show. I unsubscribed. Check this link: https://youtu.be/eMrFV2rnHlo

First things first I'm from the Pharmacy industry …. the big pharma that is the villain in mins of all these anti vaccination idiots. Many of whom say that big pharma lobbies to keep vaccines compulsory. Well let's tell you that if you don't vaccine the probability of you getting a communicable disease is very high! And once you get the disease the treatment is expensive than the vaccine which mind you is permanent. So I don't know why the "big pharma" would support Vaccination. But well you expect these idiots to have a shred of neurons right?

Over 3 billion dollars in awards have been paid to victims of injuries to the gut caused by vaccinations. Like all drugs, vaccines have bad side effects. Polio was already disappearing when the polio vaccine came out. It didn't require a vaccine to end the Black Death in Europe. It just ran its course. The same is true with polio. It will return at some point. And people who have been vaccinated can still get the disease, and do.

Michael W. Elice, M.D.
As a board certified pediatrician, I took the same oath as all physicians, “to do no harm.”

The latest media presentation of the measles outbreak at Disneyland as a result of unvaccinated children is very upsetting to me. We are being fed information that is essentially inaccurate by media journalists – none of whom have medical degrees – which may actually be promoting medical harm to our children.

The latest reports blaming a failure of the measles vaccine on the unvaccinated population are not accurate, and in some reports, not true at all. In fact, over the past 30 years, there have been similar numbers of measles cases reported in various areas of the United States. Studies published in leading medical journals, such as the New England Journal of Medicine, American Journal of Epidemiology, American Journal of Public Health and others around the world have confirmed small numbers, 75-140 cases of measles annually. So why then is the latest statistic of over 90 cases of measles spread over 14 states, representing tens of millions of people being billed as an epidemic?

The media would have us believe that this is a result of the fringe population of anti-vaxers who refuse to have their children vaccinated according the guidelines of the current vaccine schedule. Medical reporting has brought to light the glaring ineffectiveness of the measles vaccines in fulfilling their widely claimed promise of preventing outbreaks in highly vaccine compliant populations. In fact, measles outbreaks have occurred in populations that have been vaccinated on the average of 77%- 99%, not the so-called anti-vaxers.

Last year 1 in every 500,000 Americans came down with the measles. Nearly all recovered in a few days without serious consequences. At the same time 1 in 68 American children were diagnosed with autism or for every case of measles there were 7000 cases of autism. I ask myself which is the real epidemic here?

Do you really trust your government to do what's best for you? The pharmaceutical companies are making billions off the vaccines and their lobbyists are paying off the politicians to promote vaccinations. As with everything, follow the money. These so-called scientific studies saying vaccines are safe are paid for by the pharmaceutical companies that manufacture the vaccines.

I feel like autism is on the rise because having older parents is on the rise, I am a member of Gen Z, and one of my parents is a part of the later baby boomers and the other is an early gen Xer. Many of my friends have similar ages for their parents. And it has been well documented that having older parents lead to increased rates of autism.

would you eat foil? No cuz it’s not good for your body. Would you eat a rubber glove? No cuz it’s not good for your body. Did you know there is aluminum in vaccines? Did you know there’s latex rubber in vaccines??? Did you know there is mercury in vaccines? I am not anti-vaccines I am pro- let’s fix these vaccines. But if refusing to put aluminum mercury and rubber in my newborn child makes me crazy then I’ll be crazy.
