Is it okay to have protected sex on the same day after receiving the HPV 9-valent vaccine?
Generally, after receiving the HPV 9-valent vaccine, if there is no adverse reaction on the same day, it is acceptable to have sexual intercourse with a condom. However, if any adverse reactions occur, sexual activity should be avoided. The explanation is as follows:
Most people do not experience severe side effects after receiving the HPV 9-valent vaccine; some may only experience temporary reactions such as mild pain, redness, or swelling at the injection site, or fever. If the recipient feels well after vaccination without any discomfort, and uses a condom to prevent other sexually transmitted diseases, sexual intercourse is generally permissible.
If severe adverse reactions such as persistent fever, rash, or difficulty breathing occur after vaccination, medical attention should be sought immediately, and sexual activity should be avoided during this time to prevent worsening of symptoms or interference with the observation of the condition.
After receiving the HPV 9-valent vaccine, individuals should remain at the vaccination site for 30 minutes for observation to monitor for any adverse reactions. Personal hygiene should be maintained before and after sexual intercourse, keeping the affected area clean to avoid bacterial infection.
