Is it okay to have sexual intercourse the night before receiving the HPV 9-valent vaccine?

Generally speaking, "engaging in sexual activity" refers to having sex, and "nine-valent" refers to the nine-valent recombinant human papillomavirus (HPV) vaccine. It is acceptable to have sexual intercourse the night before receiving the nine-valent recombinant HPV vaccine. The detailed explanation is as follows:

The nine-valent recombinant HPV vaccine is primarily used to prevent HPV infection and thereby reduce the risk of related diseases, such as cervical cancer. Sexual activity itself does not directly affect the effectiveness of the vaccine or increase the risk of adverse reactions following vaccination. Therefore, having sexual intercourse the night before receiving the nine-valent recombinant HPV vaccine will not negatively impact the vaccination process.

If symptoms such as fatigue, fever, or local infection occur before vaccination, it is recommended to postpone the vaccination until full recovery. These symptoms may interfere with the observation and assessment of post-vaccination reactions. Additionally, after vaccination, it is important to follow medical advice and pay attention to any bodily reactions.
