Today I would like to share MY WORD on vaccinations. First, I believe you should know to appreciate my credentials and whether I can speak on this subject authoritatively. For many years I was a Research Scientist in the field of Virology and Infectious Diseases at the National Institutes of Health, eventually reaching the position of a Branch Chief of the Laboratory of Virology and Rickettsiology. I had already completed my training as a pediatrician and to this day remain Board Certified in Pediatrics. I practiced General Pediatrics in Frederick, Maryland for 7 years. Following that I founded an Holistic Health Center and ran that for 6 years until the community force me to close my doors. Unfortunately, the medical community of Frederick Maryland remains to this day in the Dark Ages when it comes to non conventional approaches to therapy and prevention of disease. And I am not afraid to say this to my Frederick readers!

So I have been cross trained in several different disciplines of the medical profession. I have mentioned before that my approach to evaluating knowledge employs the disciplines of Logic and application of the principle of Uccum’s Razor. I have prided myself in being able to evaluate the pros and cons of a particular argument and extract what I think might be a position closer to what might be considered “Truth.” Now I fully well realize that this is my own opinion, but the fact that I have some credentials and apply the two principles mentioned above should give some value to my opinions. Well, enough of my credentials. The reader is referred to my Curriculum Vitae in the main body of the web site; www.drtauraso.com.

Let us begin by saying that I do not think most people would want to return to the days when the scourges of smallpox, polio, dysentery, measles, scarlet fever, and even Yellow Fever plagued our country. We are now enjoying the benefits if considerably improved health status both because of public health matters AND vaccines.

When I went to medical school in 1956, it was just after some of the greatest polio epidemics we ever encountered in the US, I was able to observe hospital wards containing left over Iron Lungs which were used in individuals suffering with advanced polio. Within a year of two these Iron Lungs disappeared because they were not needed anymore. Why? Because the polio vaccine completely eradicated polio from the scene. The relative effectiveness and value of the inactivated Salk and the live Sabin vaccines can be the subject of a future Blog. But, we must realize that the polio vaccine eradicated polio from the United States and most of the world.

The smallpox vaccine was very effective in preventing smallpox until the smallpox virus was ENTIRELY eradicated from the entire world.

Yellow Fever was eradicated not because of the Yellow Fever Vaccine but rather from the elimination of the mosquito vector carrying the virus. It may be interesting to note that although most of us do not ever think of Yellow Fever as being a problem in the Northern Hemisphere, in the mid 1850's one of the largest epidemics of yellow fever killing thousands of people occurred in Philadelphia.

Other diseases, such as measles, mumps, whooping cough, and diphtheria, and now chicken pox were eradicated by vaccines. Scarlet Fever which killed so many and left yet another group of people with permanent heart disease was eventually eradicated with the widespread use of antibiotics which killed the streptococcus bacterium causing scarlet fever..

Be that as it may, now we worry about heart disease and cancer when our not-to-distant ancestors were dead by their 20's not getting old enough to get these diseases of older age.

As a result, we have gotten complacent and we in the US are noted for having short memories and attention spans. So since we forget about the scourges of the past, we embark upon protestations to eliminate vaccines because some believe vaccines may cause problems of their own. Although there are some complications of all vaccines, these complications do not reach the level of destruction cause by the diseases which they prevented and cured.

Many are concerned about the use of Thimerosal, a mercury-containing substance used in vaccines as a preservative. These concerned individuals are trying to relate the use of Thimerosal in the increased incidence of ADHD and Autism. The fact that Thimerosal has been used for many years and recently has been removed from most vaccines with the incidence of these diseases continuing to rise appears to elude the critics of Thimerosal. Table 1 lists those vaccines still containing Thimerosal

Table 1. Thimerosal Content of Vaccines Routinely Recommended for Children 6 Years of Age and Younger - (updated 7/18/2005*)
*Since this update, a biologics license application was approved for Rotavirus Vaccine, Trade name-RotaTeq (Merck), that is thimerosal free and never contained thimerosal.

** Thimerosal is approximately 50% mercury (Hg) by weight. A 0.01% solution (1 part per 10,000) of thimerosal contains 50 µg of Hg per 1 mL dose or 25 µg of Hg per 0.5 mL dose.
*** The term "trace" has been taken in this context to mean 1 microgram of mercury per dose or less.
1 HibTiITER was also manufactured in thimerosal-preservative containing multidose vials but these were no longer available after 2002.
2 Children 6 months old to less than 3 years of age receive a half-dose of vaccine, i.e., 0.25 mL; children 3 years of age and older receive 0.5 mL.
3 A trace thimerosal containing formulation of Fluzone was approved on 9/14/02 and has been replaced with the formulation without thimerosal.
4 FluMist is not indicated for children less than 5 years of age.

This Table was updated on 7/18/05 and so it is a bit outdated.

If one is really concerned, one can eliminate those vaccines containing Thimerosal, but my personal belief and scientific judgment does not support the belief that Thimerosal is a problem.

It is my belief that ADHD and Autism a expressions of Cerebral Allergies. Our studies and treatment confirms this. Readers are referred to what is written in the main www.drtauraso.com web site.

It is unfortunate that when groups are formed with one narrow goal that the groups with their vested interests, no matter how unfounded they may be, continue. These groups begin to have a life of their own and all the logic and application of the Principle of Occum’s Razor cannot and, more importantly, WILL not deter them from their goal. Money begins to go into these scientifically deprived projects and they begin to grow as more money supports them.

So I appeal to those who still retain a logical mind to evaluate the importance of vaccines in their lives, especially in the lives of their children. I do not quarrel with the removal of Thimerosal from vaccines because, if we can eliminate the use of a toxic substance – and mercury is a toxic substance – and find a better alternative to make vaccines safer, let us do it.

The few who do not allow their children to get vaccinated are enjoying the benefits of the herd immunity created by all those who do vaccinate. As long as those who refuse vaccination are in small numbers the herd immunity protects them even though they do not contribute to this herd immunity. But, if the majority decide not to vaccinate there will not be the protective herd immunity and we will regress to the times when the diseases we mentioned will again be rampant.
