Some women experience reactivation of HPV infection in their 50's due to weakened immune system and weakened immune memory. Is it outside the realm of possibility that giving the HPV vaccine to those already infected by the vaccine types could prevent/control future virus reactivation. Isn't that essentially what the Shingles vaccine does?
Let's say someone tests positive for hpv18 in their 20's and decides to get the HPV vaccine to prevent against getting other hpv strains that the vaccine protects against. In theory, wouldn't this person also have a lowered risk of hpv18 reactivating when they're older? There should be some residual benefits of the vaccine against already infected hpv types.
