Long-lasting Protection: HPV Vaccine's One Dose Prevents Infection for 3+ Years
A single dose of the HPV vaccine is highly effective at preventing infections over three years, lowering rates of cervical cancer and other diseases linked to the virus, according to a new study in Kenya. A single-dose strategy would extend supplies of the vaccine, lower costs, and simplify distribution, making vaccination a more viable option in countries with limited resources. The W.H.O. estimates that if widely deployed, a single-dose strategy could prevent 60 million cervical cancer cases and 45 million deaths worldwide over the next 100 years.
