⁣This referenced commentary by Barbara Loe Fisher, co-founder and president of the National Vaccine Information Center, describes recent efforts by the vaccine industry to discredit the acellular pertussis vaccine (DTaP) in order to bring back the more toxic old whole cell pertussis vaccine (DPT) that has not been given to babies in America for 20 years. She documents how the B. pertussis bacterium started mutating in the 1950s to become more vaccine resistant.
