Which vaccine can be given to a pregnant woman?

• A. Hep A/B/polio/meningococcal
• B. Influenza vaccine
• C. Measles, mumps, rubella (MMR) vaccine
• D. Varicella vaccine

Answer: (A)

The key idea is that vaccines given during pregnancy should be inactivated, so they cannot cause infection in the mother or fetus. Live vaccines are generally avoided in pregnancy because of theoretical risks to the developing baby.

The option that groups vaccines known to be inactivated and safe for use during pregnancy includes Hepatitis A, Hepatitis B, the inactivated polio vaccine, and meningococcal vaccines. These can be administered when there's a clear medical indication, under a clinician’s guidance.

Live vaccines like MMR and Varicella are typically deferred until after delivery due to their live components. Influenza vaccine is also inactivated and commonly recommended during pregnancy, but the option highlighted is the one that aligns with the safe-in-pregnancy, inactivated-vaccine principle.
