UK offers HPV vaccines to boys, aims to stop 100,000 cancer cases

HPV is a sexually transmitted virus linked to more than 99% of cervical cancers, as well as 90% of anal cancers, about 70% of vaginal and vulvar cancers and more than 60% of penile cancers.

PHE said that from September this year boys aged 12 and 13 in Britain will be offered the shots as part of a government health programme.

Since UK girls began getting the HPV vaccine in 2008, studies have shown that infections with some key types of the virus have fallen by 86% in 16 to 21 year-olds in England. A Scottish study also showed the vaccine had reduced pre-cancerous cervical disease in women by up to 71%.

Robin Weiss, a professor of viral oncology at University College London, said the extension of the HPV programme "should be a win-win situation".

"The HPV vaccine has enjoyed 10 years of success in protecting girls from acquiring cervical cancer as women," he said in an emailed comment. "It appears clear ... that vaccinated boys will themselves benefit from not getting cancer of the penis, anus, and a diminished risk of head and neck cancer."
