Medical Experts Outlines Safe and Unsafe Vaccines During Pregnancy

Obstetricians note that inactivated influenza, Td/Tdap, and recommended Covid-19 vaccines are considered safe during pregnancy to protect mothers and pass antibodies to babies.

Live attenuated vaccines such as MMR and varicella are generally avoided during pregnancy due to containing weakened live organisms.

Accidental administration of a live vaccine before knowing of a pregnancy is not an indication for pregnancy termination, though patients should consult their doctor.
