Introduction
It is not recommended to engage in excessive or frequent sexual activity before and after receiving the 9-valent vaccine; however, moderate intercourse generally does not affect the vaccine's preventive efficacy. Women who are sexually active should undergo routine cervical cancer screening, including TCT (liquid-based cytology) and HPV testing, prior to vaccination. If any abnormalities are detected, they should receive appropriate treatment under the guidance of a healthcare professional before proceeding with standard vaccination.

It is not recommended to engage in excessive or frequent sexual activity before and after receiving the HPV nonavalent vaccine. Occasional intercourse generally does not affect the vaccine's preventive efficacy.

The nonavalent vaccine refers to the 9-valent HPV (human papillomavirus) vaccine. Sexual activity usually does not interfere with the effectiveness of the nonavalent vaccine, so it is acceptable to have sex before and after vaccination. Receiving the nonavalent vaccine does not impact sexual life; however, proper protective measures must be taken. This is because, during the initial period following vaccination, women’s bodies have not yet produced sufficient levels of antibodies. Therefore, it is advisable to use condoms before sexual intercourse to prevent HPV infection. Only after the body has generated adequate specific antibodies against the nine targeted HPV strains can effective protection against HPV transmission through sexual contact be achieved, thereby helping prevent cervical cancer.

Women who are sexually active should undergo routine cervical cancer screening—TCT (liquid-based cytology) and HPV testing—before receiving the nonavalent vaccine. If any abnormalities are detected, they should receive appropriate treatment under the guidance of a healthcare professional prior to proceeding with standard vaccination.
