If you are pregnant and do not know that you are pregnant and have received the New Crown vaccine, it is recommended that you suspend subsequent vaccinations and wait until the pregnancy is over to receive the vaccine. It is not recommended to terminate the pregnancy directly because of the new coronavirus vaccine. You can decide whether to continue the pregnancy under the guidance of your doctor after completing the relevant examinations. Neocoronavirus vaccine is a new type of coronavirus vaccine that helps the body to fight against neocoronavirus infection by causing the body’s immune system to develop an immune memory. Pregnancy is a contraindication to vaccination with the new coronavirus vaccine. There is a lack of large data on vaccination with the new coronavirus vaccine during pregnancy, so the effects of the new coronavirus vaccine on pregnant women and the fetus are not yet very clear, and through the study of the limited data, it has not been found that there are any obvious adverse consequences or risks associated with the vaccination with the new coronavirus vaccine during pregnancy. Therefore, if you do not know whether or not to continue your pregnancy and have received the new coronavirus vaccine, it is recommended that you go to the hospital in time to complete the ultrasound and other examinations, and if there is no abnormality, you can go to the doctor’s guidance. If there is no abnormality, you can continue the pregnancy under the guidance and advice of the doctor, pay attention to regular obstetrical examination, and closely observe the condition of pregnancy; if the obstetrical examination reveals abnormalities in the fetus, you can terminate the pregnancy under the advice of the doctor if necessary. In addition, breastfeeding is not a contraindication to vaccination, and the vaccine can be replenished at the end of pregnancy. Pregnant women are susceptible to the new coronavirus and are more likely to develop severe disease after infection, and newborns born to mothers infected with the new coronavirus are also at higher risk of complications than ordinary newborns. Therefore, pregnant women should take precautions to prevent infection by wearing masks and minimizing visits to crowded places.
