May 16 2024BMJ The human papillomavirus vaccination programme in England has not only been associated with a substantial reduction in cervical disease, but has done so in all socioeconomic groups, finds a study published by The BMJ today.
In England, the HPV vaccination programme began in 2008, with catch-up vaccination for 14-18 year olds from 2008-10. But because cervical cancer rates have always been higher in the most deprived groups, there is concern that HPV vaccination could benefit those at greatest risk of cervical cancer the least.
Between 1 January 2006 and 30 June 2020 there were 29,968 diagnoses of cervical cancer and 335,228 of grade 3 precancerous cervical lesions in women aged 20-64 years. The highest rates remained among women living in the most deprived areas, but the HPV vaccination programme had a large effect in all five levels of deprivation.
For women offered catch-up vaccination at age 14-18, CIN3 rates decreased more in those from the least deprived areas than from the most deprived areas. However, for cervical cancer, the strong downward gradient from high to low deprivation seen in the older unvaccinated cohort was no longer present among those offered the vaccine.
As such, they conclude: "The HPV vaccination programme in England has not only been associated with a substantial reduction in incidence of cervical neoplasia in targeted cohorts, but also in all socioeconomic groups."
