We’ve been giving HPV vaccine to girls for several years now, but recently the AAP’s immunization experts have recommended that boys also start to receive it. HPV is the name for a group of viruses that cause dangerous and unsightly genital warts; the warts are a known cause of cancer. We usually start offering this vaccine at the 11 year checkup visit. It is a three-shot series. While OHP and most insurances are covering it, we advise you to verify coverage with your own insurance company before the vaccine is given. We charge $143 for each dose and the cost does become patient responsibility if not covered by insurance.
