Dr. Lü Lizheng reply Obstetrics and Gynecology

The response is that vaccination can still be administered.
However, if one has already contracted the papillomavirus, the treatment may not be effective.
The vaccine can prevent 85% of viral infections.

Yes, you can still receive the cervical cancer vaccine (HPV vaccine) even if you have had sexual intercourse. The HPV vaccine is designed to protect against certain strains of the human papillomavirus (HPV) that are known to cause cervical cancer and other related diseases. It is most effective when administered before the onset of sexual activity, but it can still provide benefits even after you have become sexually active.

The HPV vaccine is effective in preventing approximately 85% of HPV infections, particularly the high-risk types that are most commonly associated with cervical cancer (such as HPV types 16 and 18). If you have already been exposed to a specific type of HPV, the vaccine will not be able to treat or prevent diseases caused by that particular strain. However, it can still protect against other strains that you have not yet encountered.

It is important to complete the full vaccination series, which typically consists of three doses. The full protective effect of the vaccine is achieved after completing all doses, and it is recommended to follow the vaccination schedule as advised by your healthcare provider. If you have concerns about your sexual history or potential exposure to HPV, discussing these with your healthcare provider can help you make informed decisions about vaccination and any necessary screenings.

In terms of sexual activity after vaccination, there is no evidence to suggest that having sex after receiving the vaccine diminishes its effectiveness. Therefore, if you have received the vaccine, you can engage in sexual activity without worrying about affecting the vaccine's efficacy. However, it is always advisable to practice safe sex, including the use of condoms, to reduce the risk of sexually transmitted infections (STIs) and unintended pregnancies.

Additionally, regular cervical cancer screenings, such as Pap smears, are essential for sexually active individuals, regardless of vaccination status. These screenings help detect any abnormal changes in cervical cells early on, allowing for timely intervention if necessary. The HPV vaccine does not replace the need for regular screenings, and it is crucial to maintain a routine check-up schedule as recommended by your healthcare provider.

In summary, receiving the HPV vaccine after having sex is not only possible but also beneficial. It can provide protection against HPV strains that you may not have been exposed to yet. Always consult with your healthcare provider for personalized advice and to address any concerns you may have regarding sexual health and vaccination.
