Background Human Papillomavirus (HPV) is the leading cause of cervical cancer. HPV vaccination among girls (ages 9–14) is an effective way to prevent infection. Since 2012, Brunei Darussalam has implemented the National School-based HPV Vaccination programme which aims to vaccinate all female school students of 10–17 years old. This study was conducted to calculate and descriptively compare the coverage rates of all private and government secondary school students at both national and district levels, along with the parental consent rate. Methods HPV vaccination records of all female students between January 2012 and December 2015 were retrospectively extracted from the School Health Services, Ministry of Health. Descriptive statistics were used to report the overall and annual vaccination coverage rate (by district, class year, nationality and type of school) and parental consent rate. Results A total of 27,178 female students were recorded during the study period, with an overall complete dose coverage rate of 85.8% (95% CI: 85.4%, 86.2%) and 90.8% (95% CI: 90.4%, 91.2%) for all and Bruneian female students, respectively. A similar trend could be observed each year, where there is a decrease in the coverage rate from the first, second and complete doses. Brunei-Muara had the lowest vaccination coverage and parental consent rates among the country's four districts. We also observed higher HPV vaccination coverage rate for government students. Parental consent rate of Bruneian students were considerably higher than that of non-Bruneian students. Conclusion Overall, the national school-based vaccination programme has achieved a high complete dose coverage rate in its first 4 years of implementation. Issues identified for this programme are vaccine cost and difficulty to reach students who have missed their scheduled vaccination in schools. The programme can be further improved by identifying other barriers of accepting and completing their HPV vaccine dose schedule.
