Hpv 18

Women born in the 1990s had a significantly lower HPV infection rate compared with those born a decade earlier — a finding that allowed researchers to connect greater HPV vaccination coverage with direct protection and herd immunity.

The immunogenicity of two doses of the quadrivalent HPV vaccine is comparable to that of the traditional three-dose schedule in adolescents up to 120 months after the last dose is given, according to a follow-up of a randomized control clinical trial.
