Newborns and infants have the highest rates of death from pertussis and need extra protection from the Tdap shot that their mother got during her third trimester.
Influenza and Tdap vaccination rates among pregnant women are still much lower than they should be, putting these moms and their babies at risk to get a vaccine preventable disease.
Herd immunity is not junk science or a false theory. Herd immunity is real, it works, and explains how people in a community are protected from a disease when vaccination rates are above a certain threshold.
Pertussis cases and deaths are down from the pre-vaccine era.
