What is one of the reasons for using inactivated vaccines during pregnancy?

Inactivated vaccines are favored during pregnancy primarily because they do not pose a risk to the developing fetus. Unlike live vaccines, which contain a weakened form of the virus or bacteria, inactivated vaccines are made from killed pathogens or components of pathogens that cannot replicate or cause disease. This means that they are considered safer for pregnant individuals, minimizing the risk of any negative effects on fetal development.

Using inactivated vaccines can help protect both the pregnant person and the fetus from preventable diseases, as the pregnant individual can generate an immune response and pass on protective antibodies to the fetus. This protection can be particularly important during pregnancy when the body’s immune system is naturally altered, making the individual more susceptible to certain infections.

Other options do not accurately reflect the reasons for using inactivated vaccines during pregnancy. For instance, the effectiveness of an inactivated vaccine compared to a live vaccine is not the primary concern in this context, and requiring multiple doses, while sometimes true, is not an inherent characteristic that justifies their use during pregnancy. Similarly, production cost does not influence their selection during pregnancy; safety for both the mother and the fetus is paramount.
