Which vaccine is contraindicated during pregnancy?

The correct answer is the live attenuated vaccines, such as the MMR (measles, mumps, and rubella) vaccine, which are contraindicated during pregnancy due to the potential risk to the developing fetus. Live attenuated vaccines contain a weakened form of the virus, and although they are generally safe for healthy individuals, there is a concern that these live viruses could potentially cause infection in a pregnant woman and, in turn, affect the fetus.

In contrast, other vaccines like the influenza vaccine and the tetanus vaccine are inactivated or not live, making them safe to administer during pregnancy. The flu vaccine is recommended for pregnant women to protect both the mother and the unborn child from complications related to influenza. Similarly, the tetanus vaccine is crucial for preventing tetanus infections in mothers, which can lead to severe complications for both the mother and newborn.

COVID-19 vaccines have also been studied extensively and are recommended for pregnant individuals, as the potential benefits of vaccination in preventing severe illness outweigh the risks. Current health guidelines support the use of these vaccines during pregnancy to provide immunity against COVID-19 and reduce the risk of adverse pregnancy outcomes associated with the disease.

Therefore, live attenuated vaccines remain the only category that is explicitly contraindicated for
