The Tdap vaccine, which protects against tetanus, diphtheria, and pertussis, is recommended for administration during pregnancy because it helps protect both the mother and the baby from whooping cough, a serious illness that can be particularly severe in infants. By receiving the Tdap vaccine during pregnancy, women can transfer antibodies to their unborn child, thus providing early immunity.

This vaccination is especially important since the CDC advises that pregnant women receive the Tdap vaccine during the third trimester of each pregnancy, ideally between 27 and 36 weeks. This timing ensures that maximum antibodies are passed to the fetus before birth, helping to provide newborns with protection during their early months when they are most vulnerable and too young to be vaccinated themselves.

In contrast, other vaccines such as the HPV vaccine, the live attenuated influenza vaccine (LAIV), and the MMR vaccine carry considerations or contraindications for use during pregnancy. The HPV vaccine, for example, is generally not administered during pregnancy due to the lack of enough safety data. The LAIV, which is made with live viruses, is contraindicated for pregnant women because of potential risks associated with the live virus. Similarly, the MMR vaccine is not recommended during pregnancy because of the live components in
