The HPV vaccine is a small amount of HPV virus that will produce antibodies after planting in the body, and the body will have certain side effects after the vaccination. You can start taking folic acid tablets after the HPV vaccination, and the best time to get pregnant is three months after both husband and wife take them together, which can effectively prevent the occurrence of fetal neural tube abnormalities. If you get pregnant during the HPV vaccination, you need to stop the vaccination and wait for the baby to be born before injecting the rest of the shots. Although the vaccine does not have a significant impact on the health of the baby, it is important to do all the screening tests during pregnancy, and amniocentesis, or non-invasive DNA testing can be done directly during the fourth and a half to fifth and a half months of pregnancy.
