These women were older, and were high throughput screening assay not all in school and inequalities in coverage have been observed and reported [21]. Bowyer et al. quantitatively assessed the knowledge and awareness of HPV and the vaccine, amongst schoolgirls who had already been offered the HPV vaccine in the targeted UK vaccination programme [23]. In this cohort, knowledge about HPV infection was relatively

low, and only 53.1% participants were aware that HPV could cause cervical cancer. Approximately half of the participants were aware that cervical screening was still required after HPV vaccination. In our data analyses, although the women studied were from the catch-up arm of the programme, we observed approximately half of the vaccinated cohort attending cervical screening (55.2%). Analysis of factors potentially affecting uptake

of health services available for primary cervical cancer prevention VE 822 in the UK, highlighted that women who originate from more socially deprived areas are less likely to engage with the services available. Moreover, 9758/30,882 (31.6%) had neither attended for screening nor received the HPV vaccine. However, although social deprivation affected the initial engagement, once women engaged, at least in this age group, there was no significant difference in clinical outcome. Cervical cancer rates are higher in women from more socially deprived backgrounds [24]. However, data from

our study suggests that this is a consequence of women from more socially deprived areas not Dipeptidyl peptidase engaging with the current primary cervical cancer prevention strategies in the UK. In women offered HPV vaccination through the catch-up arm of the programme, this study shows a protective effect with a reduction in cytological abnormalities from 16.7% in unvaccinated women to 13.9% in vaccinated women. However, the level of abnormalities detected in the vaccinated women is still relatively high, potentially reflecting acquisition of the virus prior to vaccination. This data suggests that the catch-up arm of the vaccination programme has not had a substantial protective effect and a higher impact on cytological abnormalities is anticipated in the target group, who may not have been exposed to the virus prior to vaccination. Women who have chosen to receive the HPV vaccination and attend for cervical screening may be more health conscious, and this may be reflected in their sexual behaviours. It is therefore possible that they may be less likely to become infected with HPV, accounting for the reduction seen in the proportion of cytological abnormalities.
