CHAPTER 1: Vaccine History 101

Introduction: Immunizations



Immunizations have been getting a lot of attention lately and it seems to be the trending topic at dinner parties. In this blog we will try to debunk the myths and fallacies of immunizations and look at the scientific facts. It is important that as a population we join together and educate people on the truth and importance of vaccines. Although it is true that some vaccines have caused sickness and fatality in the pass, we have to remember that like all medical procedures there is always a risk. And the likelihood that something bad might happen, is so minimal it does not outweigh the good.
We will hopefully find answers to questions like; should I delay vaccination for my infant? Does a vaccine really cause autism? Is it mandatory to immunize my child? But before we delve deeper into debunking myths about vaccines, we must first learn a little history on vaccines see how they have developed over the century.

A little lecture on vaccine history


In the early 1900s humans were dying of infections and diseases. Over the course of 100 years, right after the introduction of vaccines into the world, we have been able to significantly reduce death caused by a preventable infection. 


The concept of a vaccine was introduced to the world by a man named Edward Jenner. Edward Jenner was the first to successfully use cow pox as a form of inoculation against small pox.  And his method was used in developing a vaccine that completely eradicated small pox from the world some 200 years later.  Here is a timeline of the history of vaccines.

1798Edward Jenner published his work on the development of a vaccination that would protect against smallpox.
1879Louis Pasteur created the first live attenuated bacterial vaccine (chicken cholera)
1885Louis Pasteur first used rabies vaccine in humans.
1896Cholera and typhoid vaccines were first developed.
1945Inactivated influenza vaccine was first licensed in the U.S.
July 18, 1973Measles and mumps virus vaccine, live (M-M-Vax by Merck) was licensed.
1981The first hepatitis B viral vaccines, developed by Merck and also by the Pasteur Institute, were licensed. Both had independently developed plasma-based hepatitis B viral vaccines.
June 8, 2006FDA licensed the first vaccine developed to prevent cervical cancer (Gardasil by Merck)

So recapping a bit on the timeline and history of vaccines we notice that over the course of a century or so. We have come up with vaccines for a lot of infectious diseases.  And with the visual up top we see that for the most part, the majority of these diseases that were once the leading cause of death a century ago are no longer an issue. Drawing up a  conclusions on the visual above, it seems that after the introduction of vaccines our leading cause of diseases are no longer of an infectious origin.  Learning the truth about vaccines is very important, over the years we forget how horrible these diseases really are. Lets not get caught up in all the frenzy of "parents against vaccines" lets make educated decisions and protect ourselves from deadly diseases.

  1. Karen, this is an excellent introduction to the controversies surrounding vaccinations. Your brief history of vaccines is presented in a concise and organized format; the graphical comparison between ‘pre-vaccine era morbidity’ and ‘most recent reports of cases’ really accentuates the impact that vaccination has on public health. Also, the decision to use an entertaining PSA video that depicts popular archetypes (zombies) shows that you’re ‘marketing’ to the masses, which is a great way to disseminate scientific information. I look forward to reading your next chapter.

  4. I like your background! The blog is easy to read, follow and is very well organized. I like that you started out your blog introduction with some history to see how far vaccines has developed over the years. The pre-vaccine era vs the vaccinated chart is a great way to show how vaccine has done good for humanity. This was very informative.

  5. This is amazing. The way this blog is organized is extraordinary; however, I would like to know more what really caused this sudden rise in the fall of vaccination - basically the recent Andrew Wakefield controversy. The main question that made vaccines a controversial topic is: why are parents fearful to vaccinate their children, or even to a great extent get vaccinated themselves, is it because they don't trust science or they want to just be on the safe-side. I think it will be great to address the current solutions that the medical / public health organizations are trying to take to tackle this problem.
