Correct answer: E — Offer Tdap vaccination during this pregnancy

Tdap in each pregnancy helps protect the newborn against pertussis through passive antibody transfer. Delaying until postpartum misses this neonatal protection window. Live vaccines such as MMR and intranasal live influenza vaccine are avoided in pregnancy. Inactivated vaccines indicated in pregnancy are safe and important.
