Sierra Leone surpasses HPV vaccination targets and narrows cervical cancer gap

Sierra Leone vaccinated more than 1 million girls in a week-long multi-age HPV campaign, reaching 116% of its initial target and expanding eligibility to ages 11–18. The campaign is part of a national strategy that combines vaccination with expanded screening and treatment as the country advances toward the 2030 cervical cancer elimination targets.

Sierra Leone has exceeded its national target in a recent human papillomavirus (HPV) vaccination campaign, vaccinating more than one million girls. The campaign used a multi-age cohort strategy and expanded age eligibility to girls aged 11 to 18. It was led by the government with technical support from WHO and partners including UNICEF, UNFPA and Gavi. The effort is part of a broader national strategy that combines vaccination with expanded screening and timely treatment services to reduce cervical cancer. Key facts: - More than 1 million girls were vaccinated, achieving 116% coverage against an initial target of about 868,300. - The campaign expanded eligibility to girls aged 11–18 years and used a multi-age cohort approach to increase population immunity. - Of those vaccinated, 66% were in school and 34% were out of school; 64% of schoolgirls and 53% of out-of-school girls received the HPV vaccine for the first time. - Safety surveillance reported 514 adverse events following immunization, with two classified as serious; these events were investigated and managed. - Vaccine utilization reached 107%, and national vaccination coverage is reported to exceed 70%, contributing to progress toward global elimination targets. Summary: The campaign increased reach and equity in HPV vaccination across Sierra Leone and narrows gaps in protection that contribute to cervical cancer risk. WHO and other partners supported planning, training, safety monitoring and quality assurance during the campaign. Officials emphasize sustained investment and continued integration of vaccination, screening and treatment services as priorities for maintaining progress toward the 2030 elimination goals.
