Which vaccine is contraindicated in pregnancy:
Show Hint
Live attenuated vaccines are avoided in pregnancy.
Updated On: Jun 23, 2026
- Chicken pox
- Rabies
- Tet toxoid
- Hepatitis B
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: When deciding vaccine safety in pregnancy, classify each one: live attenuated agents are off-limits, while killed, subunit, and toxoid vaccines are permitted.
Step 2: Varicella (chicken pox) vaccine is live attenuated and therefore cannot be given to a pregnant woman.
Step 3: Rabies (inactivated), hepatitis B (recombinant subunit), and tetanus toxoid (toxoid) carry no live organism, so they are acceptable - tetanus toxoid is even part of routine antenatal care. The single contraindicated choice is the chicken pox vaccine.
