She still might want to think about it since she’s in the right age group to receive it. It’s not a slur on her sexuality, but she could be exposed to HPV even in marriage. I caught it from my fiance (now-husband) who apparently caught it from his exW and harbored the virus for awhile with no symptoms. I wish the vaccine had been available back then (in the early 80s).
Can you be too old to receive the HPV vaccine?
