I know for a fact that thimerosol can affect some people--it bothered me greatly when I first used contact lenses over 30 years ago. The first day I used them, the whites of my eyes turned very red and painful. The doctor told me that it was the preservative (thimerosol) in the solution and that 1 in 5 people had problems with it. I changed to a non-preservative single use solution and was fine after a round of treatments with cortisone to get my eyes calmed down.
So, imagine injecting that stuff into some children who are very sensitive to it and in multiple doses. If a little would do that to my eyes in my early 20s, what might it do to infants' brains when they are small without well developed immune systems?
At the very least, this deserves more consideration and research. We do need vaccinations, but there must be a less potentially harmful preservative.
Excellent point.
Some researchers have not grasp the concept that people are genetically diverse and the argument that something "does not affect everyone" is bogus.
