- HPV vaccination is crucial for preventing cervical cancer in adolescent girls, but many are under-vaccinated due to cost and logistics.
- Research indicates that a single dose of the HPV vaccine may be as effective as two doses, which led to a large trial comparing the effectiveness of one versus two doses of bivalent and nonavalent vaccines.
- The ESCUDDO trial, involving over 20,000 girls in Costa Rica, aims to evaluate vaccine efficacy through follow-up visits and comparisons with unvaccinated women.
