A member asked:

If a young woman who received the gardasil9 hpv vaccine is exposed to high risk hpv viruses about 40 years later, will she develop cervical cancer?(because the immune memory acquired by the vaccine is lost after about 40 years?

Even without vaccination, under 1% of high risk HPV infections lead to cancer. Whether someone would be protected after 40 years is impossible to know, since the vaccine has been available and in widespread use for only 15 years. But it really doesn't matter anyway, because new HPV infections are very rare over age 40.
