It is not clear whether the New Crown Vaccine has any effect on the fetus if you are pregnant. There is a lack of clinical observation data on the safety of New Crown Vaccine for pregnant women, which makes it difficult to determine whether there will be any significant effect on the fetus. The vaccine is inactivated and may cause discomfort such as pain at the injection site and low-grade fever, but has no significant adverse effects on the body. However, due to the limited use of the vaccine, there is no authoritative information to determine whether the vaccine has any effect on the fetus. It is generally recommended that the vaccine should not be injected after pregnancy for the sake of eugenics. If the vaccine is injected during pregnancy, the pregnancy can be continued, but in the later stage, attention should be paid to regular obstetric examination, follow-up of fetal development, and stop vaccination, if abnormal adverse conditions occur, the pregnancy should be terminated in time.
