Lest we forget, vaccines are one of the greatest medical inventions of all time. Without them, we would see cemeteries filled with children who would have died before they were even five years old. In fact, the best evidence we have tells us that vaccines prevented 200 million cases of diseases in the USA alone in the five decades since 1963.
A recent study, published in AIMS Public Health, estimates that around 200 million cases of polio, mumps, rubella, measles, adenovirus, hepatitis A and rabies have been prevented in the U.S. from 1963 through 2015 as a result of widespread vaccination. The study, authored by Leonard Hayflick and S. Jay Olshansky, two leading experts on public health and infectious diseases, also discloses that about 450,000 deaths have been avoided in the U.S during this period, although other studies put that estimate of lives saved at a much higher number.
Dr. Hayflick discovered the human cell strain, WI-38, in 1962 which was critical to the safe manufacturing of vaccines, which became widespread in 1963. According to the article, the vaccines produced from the WI-38 cell line prevented almost 4.5 billion occurrences of the diseases, and stopped them from returning to infect us. Dr. Hayflick developed the foundation that allowed the world to have relative safe and very effective tools to prevent infectious diseases.
Prior to the development of WI-38, anti-virus vaccines were grown in monkey cells, which had some issues that made many question their safety, although most of the concern appeared to be overblown. However, once the WI-38 was available, it became easier to develop and produce vaccines for many viruses.
Drs. Hayflick and Olshansky wanted to see what effect that seminal event had on public health. And the numbers were incredible. Continue reading “Vaccines prevented 200 million cases of disease in the USA from 1963 to 2015”
Generally, when I write about vaccines, it’s about protecting children’s lives from vaccine preventable diseases. That itself is a noble goal for vaccines. But in case you didn’t know, there is also a CDC schedule for adult vaccines, which is as important to adults as they are to children.
Vaccines have one purpose – to protect us and those whom we love from potentially deadly and debilitating diseases. Many of us in the blogosphere have talked about the children’s schedule a lot, often to debunk claims of people who are ignorant of science, and think that the children’s vaccine schedule is causing undue harm. Yeah our intellectually deficient president, Donald Trump, thinks he knows more than the CDC, but that’s a problem shared by many vaccine deniers.
One adult vaccine I push regularly is the flu vaccine. It protects adults, pregnant women, the elderly, children, and healthy young adults from a severe infection that hospitalizes and kills more people every year than you’d think. Because flu is not really a serious disease, in some people’s minds, a lot of people decide that they don’t need the vaccine. They’d be wrong.
Just in case you were wondering, there is more to adult vaccines than just flu vaccines. There are several other vaccines indicated for adult use, including those adults with underlying health issues like diabetes, HIV and heart disease – unfortunately, the uptake for adult vaccines is depressingly low. Let’s take at the low uptake and the recommended adult vaccines schedule.

For New Year’s Day, I’m republishing the top 10 articles I wrote in 2013. Well, actually top 9, plus 1 from 2012 that just keeps going.
#10. This article was published on 3 December 2013, and has had over 5000 views. It’s one of my favorite because it shows, with scientific evidence, that the trope pushed by the vaccine deniers that better sanitation, food, and medicine reduced the mortality from these diseases. But we know it’s the vaccines, and we have brilliant science to support that fact.
One of the tropes of the antivaccination world is that vaccines didn’t stop diseases. They give credit to everything from modern medicine to better food to better sanitation. Some of the credit they give is ironic since many vaccine deniers hate most aspects of modern medicine and believe that food was better 100 years ago. You can never get enough of the contradictions and hypocrisy of the antivaccine crowd.
I think it becomes easy to dismiss the value of vaccines in ending widespread disease because almost anyone writing today about vaccines has no memory of ubiquitous and deadly epidemics of diseases. We’re almost at a point in our culture that if Twitter doesn’t report it, it didn’t happen, so infectious diseases are something that happened back when humans lived in caves, prior to the advent of social media. I happen to have been born right near the end of widespread epidemics of infectious diseases, so I don’t remember any epidemics personally, though I recall a few classmates in high school who had a few effects from polio and other diseases. Culturally, we have forgotten our past with respect to diseases. Continue reading “Why we vaccinate–103 million cases of diseases averted since 1924”
