Can Getting Immunizations Affect My Unborn Baby?

My workplace expects its employees to get several immunizations regularly. But I’m pregnant and scared of what the vaccines might do to my baby. Should I be concerned?

It's best to be vaccinated before your pregnancy when possible, but some immunizations can be given during pregnancy. These include vaccines like the inactivated flu shot (be sure not to get the nasal vaccine spray), hepatitis B, meningococcus, rabies, and tetanus, diphtheria, and pertussis (Tdap) vaccine. Both the Tdap vaccine and the flu vaccine are recommended during each pregnancy.

Some vaccines should not be given during pregnancy:

  • Measles, mumps, and rubella vaccine (MMR)
  • Human papillomavirus (HPV) vaccine
  • Chickenpox (varicella) vaccine

A doctor might recommend that a pregnant woman get immunized during pregnancy if all of the following are true:

  • there's a good chance that she could be exposed to a particular infection
  • the infection would pose a risk to her or the baby
  • the vaccine is unlikely to cause harm

For example, flu shots are recommended for everyone during flu season, and especially for pregnant women, because:

  • during flu season, exposure to flu viruses is high
  • pregnant women — especially those in late pregnancy — are at increased risk for severe symptoms from the flu
  • the vaccines are safe for pregnant women

Before you get any vaccines during pregnancy, check with your doctor to make sure they are right for you.
