Clinical trials and observations on whether the New Crown vaccine affects the health status of the fetus in the abdomen in women during pregnancy are limited. Because the data are not yet comprehensive, it is not possible to state with certainty whether Neocrown vaccination has an effect on fetal intelligence. For women who have become pregnant after vaccination or who have received the New Crown vaccine in the context of an unknown pregnancy, special medical treatment of the fetus, such as termination of pregnancy, is not recommended solely because of the New Crown vaccine. It is recommended to discontinue subsequent doses of the vaccine, and at the same time to do pregnancy checkups and follow-up examinations, and to pay attention to testing the physical condition and various indicators of the fetus such as fetal heart and lungs in daily life. For fetuses that are clearly found to have abnormalities that seriously affect the life of the pregnant woman after examination, the pregnancy can be terminated after medical evaluation. For women who know they are pregnant, it is not recommended to receive the vaccine because there are few clinical data available, and in order to ensure the health of the pregnant woman and the normal growth and development of the fetus, the state requires that the vaccination be given after the pregnancy is over.
