Tdap vaccine best given at 28-32 weeks pregnant

In the first months of life, newborns rely on their mothers’ immune systems to protect them from infections like pertussis. Pertussis infection, known as whooping cough, has become more common in infants who are too young to be vaccinated and thus protected against the illness. For these infants, their best defense is the Tdap vaccine given during the third trimester of pregnancy. Given the rising incidence of pertussis in newborns, OBGYNs have become interested to know exactly when during pregnancy is the best time to give the Tdap vaccine.
