Hundreds of women have been saved from cervical cancer thanks to a national vaccination campaign, new research has found.
The study by King’s College London and published in The Lancet noted that women who were vaccinated with human papillomavirus (HPV) between the ages of 12 and 13 had an 87 percent cervical cancer rate compared to non-vaccinated women. was less.
Among women aged 14 to 16, cancer rates were 62 percent lower and 34 percent lower among women aged 16 to 18.
Researchers say these results prove the benefits of the HPV vaccine. According to estimates from the University of Oxford, 10 million women received a single dose of the vaccine between 2009 and 2018.
Experts looked at data from the vaccination program using the vaccine Cervarix, which was given to girls on the NHS from 2008 to September 2012. A different vaccine, Gardasil, is now used and is given to girls and boys between the ages of 12 and 13.
The study estimated that as of June 2019, among those vaccinated in England, there were 450 fewer cervical cancer cases and 17,200 fewer pre-cancer cases than expected.
Dr Kate Solden of the UK Health Security Agency said the study provides the first direct worldwide evidence of cervical cancer prevention using a vaccine for two types of HPV, the virus that can trigger cervical cancer.
She said: “This represents an important step forward in the prevention of cervical cancer.”
Professor Peter Sassiani, who led the work, said: “It has been incredible to see the impact of HPV vaccination and we can now prove that hundreds of women in England can be prevented from developing cancer.
“We have known for many years that HPV vaccination is very effective in preventing particular strains of the virus, but seeing the real-life impact of the vaccine has been really beneficial.
“Assuming that most people continue to receive the HPV vaccine and go for screening, cervical cancer will become a rare disease.
“This year we have already seen the power of vaccines in controlling the COVID-19 pandemic. These data suggest that vaccination works to prevent some cancers.”
Cancer Research UK, which funded the work, said the findings were better than expected and that cervical cancer could become a rare disease thanks to vaccines combined with screening.
HPV vaccination has been introduced in 100 countries so far as part of the World Health Organization (WHO) efforts to eliminate cervical cancer.
Professor Maggie Cruickshank from the University of Aberdeen: “The scale of HPV vaccination impact reported by this study should encourage vaccination programs in low- and middle-income countries where the problem of cervical cancer is a far greater public health problem than well-established ones.
