With inequitable human papillomavirus (HPV) vaccine access globally and a programmatic focus on girls\u2010only school\u2010based delivery, many WLHIV in high HIV prevalence countries remain vulnerable to HPV and CC. We assessed the incremental impact of adding catch\u2010up vaccination for WLHIV in South Africa.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We used two independently developed HPV\/CC and HIV transmission models to predict the incremental impact of catch\u2010up HPV vaccination for WLHIV compared to routine\u2010only vaccination of girls aged 9\u221214 (90% cohort coverage) from 2020 onwards using a nonavalent vaccine (lifelong 100% protection). We assessed catch\u2010up scenarios vaccinating WLHIV aged 15\u221224 or \u226515 (attaining 90% cohort coverage), maintaining baseline CC screening. We report the predicted median annual prevalence of vaccine\u2010type high\u2010risk HPV (VT HR\u2010HPV), CC incidence and cumulative fraction of CC cases averted compared to routine\u2010only vaccination among WLHIV overall (age\u2010standardized) and by age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>With routine\u2010only vaccination, overall coverage among all WLHIV remained substantially (&gt;50%) lower than in all women for 35\u221240 years, with gaps persisting even after 80 years. Adding catch\u2010up vaccination for WLHIV aged 15\u221224 increased coverage and benefits mainly among young WLHIV, with the largest annual reductions (relative to routine\u2010only vaccination) in VT HR\u2010HPV prevalence and CC incidence for WLHIV &lt;30 years, reaching up to 36%\u201352% across models within 15 years and 38%\u2013100% after 15\u221225 years, respectively. If catch\u2010up included WLHIV aged \u226515, overall vaccination coverage among WLHIV would immediately increase to 90%, extending benefits to older WLHIV\u2014reducing peak annual relative reductions in CC incidence among WLHIV \u226550 by an extra 19% points compared to catch\u2010up vaccination of WLHIV aged 15\u221224, and shifting the peak 25 years earlier. Over 55\u221260 years, catch\u2010up vaccination of WLHIV aged 15\u221224 and \u226515 could avert up to 3%\u20138% and 14% of CC cases among WLHIV, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Catch\u2010up vaccination of WLHIV can reduce their CC burden in the short to medium term, even in the presence of girls\u2010only routine vaccination programmes with high cohort coverage.
