Termination of pregnancy is not necessary when the pregnancy is detected just after the third dose of the new CAPV vaccine, and proper pregnancy checkups and follow-up visits are recommended. There is no evidence to suggest that the third dose of CKPV has adverse effects on the body and embryo development. If pregnancy is detected after vaccination with Neocoon vaccine, abortion is not recommended and observation can be continued. As long as the pregnancy is checked at the right time and no obvious fetal abnormalities are found, there should be no cause for concern. Of course, the New Crown Vaccine is after all a newly produced vaccine, and there is a lack of extensive clinical data and studies to say with certainty that it does not have any adverse effects on embryonic development. Therefore, try not to receive the New Crown vaccine during pregnancy. Vaccination should be carried out under the guidance of a doctor, and when symptoms of discomfort occur after vaccination, prompt medical attention should be sought.
