What is the vaccine actually vaccinating against?
See comment# 7. Drug companies used thimerosal as a preservative in a number of common childhood vaccines that used to be distributed as multiple dose vials of each vaccine, e.g. 100 doses of MMR or DPT or inactivated polio, etc. MMR means the combined measles, mumps and rubella vaccine, and DPT means the combined diptheria, pertussis and tetanus vaccine. Now these combined vaccines are only administered as one single dose from a single vial for each kid.
