Which vaccine is recommended for pregnant healthcare personnel?

• A. Tetanus, diphtheria, and acellular pertussis (Tdap)
• B. Herpes zoster (shingles)
• C. Varicella
• D. Measles, mumps, and rubella (MMR)

Answer: (A)

The important idea is protecting both the pregnant person and the newborn by using vaccines that are safe in pregnancy and that reduce disease risk in early infancy. The vaccine that is recommended for pregnant healthcare personnel is the Tdap. It is safe to administer during pregnancy and is given in each pregnancy, typically in the late second or third trimester, to maximize the transfer of protective antibodies from mother to baby. This maternal antibody protection helps shield newborns from pertussis during the first months of life, when they are most vulnerable and too young to be vaccinated themselves. At the same time, receiving Tdap also protects the mother against tetanus and diphtheria.

The other vaccines listed are not routinely given during pregnancy: varicella and MMR are live vaccines and are contraindicated in pregnancy; the herpes zoster vaccine is also not routinely given during pregnancy due to safety concerns with vaccines of this type. In a healthcare setting, keeping up to date with Tdap during pregnancy is a key way to reduce risk for both patient and staff.
