1 Pertussis: Vaccine Failure, Not Failure to Vaccinate • Children's Health Defense
This is the latest peer reviewed science-not "vaccine misinformation." These studies show that the Pertussis (whooping cough) vaccine has now failed. Studies show that by five years after completion of the DTaP series, children were up to 15 times more likely to acquire pertussis compared to the first year after the series. California schools are now suffering a Pertussis outbreak (3,455 cases in 2018 compared to 14 Measles cases) affecting primarily vaccinated children.
