We have adolescents in our practice who have received the first 2 doses of the HPV series 1 or 2 months apart according to the 3-dose schedule. Can we consider their HPV vaccine series to be complete or do we need to give these patients a third dose?

People who have received 2 doses of HPV vaccine separated by less than 5 months should receive a third dose 6–12 months after dose #1 and at least 12 weeks after dose #2, regardless of their age at the time of the first dose. The recommended interval for the second dose in the 2-dose schedule (indicated when the first dose is given before age 15) is 6 months and the minimum interval is 5 months.
