Study Shows One HPV Shot Provides Strong Protection

Researchers from the U.S. National Cancer Institute and Costa Rica's Agency for Biomedical Research found a single Human Papillomavirus vaccination is as effective as two doses in preventing cervical cancer.
A trial with over 20,000 girls aged 12-16 compared two HPV vaccines with a delayed second dose and five-year follow-up against an unvaccinated group.
The study published in the New England Journal of Medicine showed a single HPV shot provides about 97% protection, confirmed for five years.
