It is possible to prepare for pregnancy and get pregnant normally after a booster shot of the New Crown Vaccine. The new crown vaccine is an inactivated virus vaccine. The vaccine cellular immunity is weak and has no infectious activity. Multiple vaccinations are needed to ensure the immunization effect, and the antibody concentration in the body will gradually decrease over time, so the inactivated vaccine in general needs to be booster vaccinated on a regular basis. According to medical experiments, the New Crown vaccine does not produce toxic effects in pregnant animals. However, due to ethical implications, there is no evidence of pregnancy and lactation, so the new crown vaccine instruction manual is contraindicated for vaccination of pregnant and lactating women. According to the Technical Guidelines for Neocoronavirus Vaccination, it is clearly stated that preparation for pregnancy is not a contraindication to vaccination and that it is not necessary to postpone preparation for pregnancy solely because of Neocoronavirus vaccination. Pregnant women who have received a booster dose of the new coronavirus vaccine can have a normal pregnancy, or if they are really worried, they can get pregnant after 3 months of vaccination, as in the case of other inactivated vaccines.
