Abstract
Immunization during pregnancy is a simple and effective way to protect the mother and child from certain infections. The immunological changes occur during pregnancy which may be responsible for the susceptibility of certain infectious diseases that increases the risk of more serious outcomes. Vaccination of pregnant women can protect to mother against vaccine-preventable infections, and in so doing potentially protect the fetus. Immunization during pregnancy can also directly protect the fetus and infant via transferred of antibodies from the mother to the fetus. This is why vaccinations during pregnancy are so important. Vaccination during pregnancy is a cost-effective strategy to improve pregnancy outcomes in India. Globally, no scientific study exist which shows the risk of fetus after vaccination of pregnant women with inactivated vaccines or bacterial vaccines or toxoids. Even live vaccines causing risk to fetus is theoretical. Vaccination with inactivated virus, bacterial or toxoid in pregnancy is risk to a developing fetus during pregnancy is theoretical. But definitely the live vaccine poses a theoretical risk to a developing fetus. Therefore, all live vaccines should be avoided during pregnancy. The developing country like India where the people can't afford these vaccines, the government should be included these vaccines in routine immunization program.
