From this article about thimerosal:

Although reliable numbers are hard to come by, autistic disorders also appear to be soaring in India, Argentina, Nicaragua and other developing countries that are now using thimerosal-laced vaccines. The World Health Organization continues to insist thimerosal is safe, but it promises to keep the possibility that it is linked to neurological disorders "under review."

Be careful what you let doctors put into you. The "First, do no harm" principle should be a key assumption about vaccines. Developing countries should be very wary about vaccines. There is often a double standard in vaccine manufacture. Notice the: Vaccine manufacturers had already begun to phase thimerosal out of injections given to American infants

What about infants who aren't in America? Do they deserve any less?
