The HPV vaccine is an inactivated vaccine. If you have intercourse on the day of HPV vaccination, it is recommended that you take protective measures such as oral contraceptives if you are planning to have a pregnancy in the near future, because some studies have found an increased risk of spontaneous abortion in people who received the HPV vaccine before conception or within 30 days after conception. In addition, if you have intercourse on the day of HPV vaccination, you should also observe whether you have any uncomfortable symptoms, as some people may experience dizziness, nausea and other uncomfortable symptoms after vaccination, and redness and swelling at the vaccination site, which may be aggravated by intercourse. The main way of transmission is through sex. Be careful not to do activities in public places such as sauna, swimming and hot springs during the entire vaccination period.
