CHIC Technical Brief on Country Decision-Making Factors: Expanding the Target Population for HPV Vaccination
This CHIC technical brief synthesizes evidence and programmatic considerations to guide country decision-making on expanding HPV vaccination beyond the primary target of girls aged 9–14, in response to a growing number of African countries adopting or considering vaccination of older girls (15–18), young women up to age 26, or boys. Grounding its analysis in WHO […]
Efficacy Of Quadrivalent Human Papillomavirus Vaccine Among Kenyan Adolescents And Young Adults Living With HIV Nine Years After Initial Vaccination
In Kenya, a nine-year follow-up of a cohort of 180 adolescents living with HIV who received three doses of the quadrivalent HPV vaccine at ages 9–14 found sustained vaccine-specific protection, with zero persistent infections detected for HPV types 11, 16, or 18 among 151 evaluable participants. Only two participants (1.3%) had any vaccine-genotype persistent infection, […]
Using Geographic information System mapping for Evidence-Based Planning to Reach HPV vaccine Target Girls and Zero-Dose Children: Experience from Jigjiga Town, Ethiopia.
In Ethiopia, a 20-day house-to-house GIS mapping exercise conducted in Jigjiga town (Somali region) between August and September 2024 revealed major discrepancies between projected and actual target populations: official estimates placed the HPV-eligible girl population at 6,770, while the headcount identified 11,300 — a 67% undercount — and 14,935 girls were ultimately vaccinated, representing 132% […]

Integrating School Engagement And Facility-Based Screening To Strengthen HPV Vaccination In Kenya.
In Kenya, a dual-strategy implementation study addressed two persistent barriers to HPV vaccination coverage — vaccine hesitancy and dependence on inconsistent school-based outreach — through complementary school engagement and facility-based OPD screening models. The Ministry of Education–led school engagement component deployed school health committees, teacher training, health club reactivation, and peer-led forums nationwide, generating qualitative […]
