While the FDA initially approved the vaccine for young girls, based on the earliest studies available on its effectiveness, we know now that everyone can benefit from being vaccinated. The HPV vaccine helps protect against penile, anal, genital, head, and neck cancers, Dr. Chalas explained, making it just as essential for young boys. And while the risk of contracting HPV is relatively small for those who have been vaccinated, the best way to prevent the spread is to ensure that both partners are equally protected.
The vaccine also isn't just for children, though it's most effective before a person becomes sexually active. "Children also have a stronger immune response to the vaccine because the immune system becomes less potent as we age," Dr. Chalas told POPSUGAR. Still, "the vaccine is now approved until the age of 45." She recommends the vaccine for anyone having sex outside of a relationship.
