Vaccine strategies and coverage rates

Assumed vaccine coverage rates (VCRs) for the scenarios assessed in this analysis were 1) 70% VCR for 9vHPV FOV (12-year-old girls only), 2) 70% VCR for 9vHPV routine GNV (12-year-old girls and boys), and 3) 70% VCR for 9vHPV routine GNV (12-year-old girls and boys) and 30% VCR for catch-up vaccination (13- to 18-year-old females and males). The 70% VCR was chosen for 9vHPV FOV and 9vHPV routine GNV vaccination strategies because these routine strategies were assumed to be carried out in a school-based manner. Furthermore, an interim target VCR of 70% was set by the Hong Kong government after the introduction of the female school vaccination program.⁵³ The 30% VCR was chosen for the catch-up vaccination strategy because the HPV catch-up program is more likely to be a public-private partnership with private clinics rather than school-based, and as a result, a lower vaccine uptake rate is expected.
