How long it takes to get pregnant after the third vaccination depends on the type of vaccine. In the case of the HPV third vaccine, it is recommended to consider pregnancy after three to six months of vaccination. If it is the third vaccination for New Crown, you can consider pregnancy after you have resumed one menstrual period after vaccination. Some vaccinations require about three to six months after vaccination before pregnancy can be considered, such as the HPV vaccine, to avoid adverse effects on pregnancy preparation. If you need to receive the third dose of the New Crown vaccine, it is recommended that you wait for the resumption of your menstrual period after the vaccination, and you can consider getting pregnant after your period is cleared. If you become pregnant unexpectedly without exceeding the required window of time after the third vaccination, you do not need to worry too much. The pregnancy can be continued with regular follow-up labor and delivery tests.
