Researchers involved in the initiative reported thatuptake rates of 64.8%, 62.7% and 48.2% were achievedfor doses 1, 2 and 3, respectively, in 1254 girls aged11–15 years who presented for vaccination, with ratesbeing highest in girls aged 14–15 years (81.0–90.7%).The high uptake rates of the regional initiative resulted inthe subsequent launch (from 2011) of a nationwideclinic-based HPV vaccination programme, jointly fundedby national and regional governments. The researchersattributed the success of the trail-blazing regionalprogramme primarily to the step-by-step strategy usedto obtain consensus among the relevant stake-holders.

School provision underway in TanzaniaHigh uptake rates in a cluster-randomised study that

compared two different methods of school-based HPVvaccination in northwest Tanzania supported theinclusion of HPV vaccination in Tanzania’s nationalimmunisation programme, according to the authors ofthe study.2

A total of 5532 girls were enrolled from 134 schoolsthat were randomly allocated to either class-based orage-based delivery using the quadrivalent HPV vaccine.Overall vaccine uptake rates were 84.7%, 81.4% and76.1% for doses 1, 2 and 3, respectively, with higheruptake rates achieved for class-based than for age-basedvaccine delivery (86.4 vs 82.0% for dose 1; 83.8% vs77.8% for dose 2; 78.7% vs 72.1% for dose 3). Based ontheir estimate that population coverage was 65–70% forthe age-based and > 70% for the class-based delivery,the researchers concluded that class-based delivery wasthe superior delivery method. HPV vaccination will berolled out via primary school provision as part of thenational immunisation programme from 2012.

Screening-programme provision proposed inHong Kong

Chinese researchers, who identified low uptake andacceptance of HPV vaccination among females in HongKong, have recommended that HPV vaccination shouldbe integrated into the current national cervical screeningprogramme.3

The researchers conducted telephone interviews withmothers of daughters aged ≤ 18 years and recruited girlsfrom secondary schools to complete a self-administeredquestionnaire. Of the 1022 mothers interviewed, 27%said that they were willing to vaccinate their daughtersand, of the 2252 girls who completed the questionnaire,6% had been vaccinated and 27% of those not yetimmunised said they were willing to receive HPV
