the worst year for pertussis in over 50 years
You'll hear this will be the worst year for pertussis in over 50 years...DESPITE vaccination of kids and adolescents.
This raises suspicions about whether there's a problem with the vaccine. And in fact, that is the concern.
About 15 years ago, CDC recommended switching to ACELLULAR pertussis vaccine instead of the WHOLE CELL vaccine for infants.
