LONDON, July 9, Xinhua News Agency (Xinhua) - The British government announced that from September this year, the coverage of HPV vaccination program will be extended from girls to boys. It is estimated that tens of thousands of cancer cases will be avoided in the next 40 years.
HPV vaccine, also known as cervical cancer vaccine, can prevent the occurrence of related cancers by preventing HPV infection, including cervical cancer, penile cancer, anal cancer, some head and neck cancer, etc. According to a model established by the University of Warwick in Britain, by 2058, 50 years after the launch of the HPV vaccination programme in the UK, the vaccine could prevent more than 64,000 cervical cancers and nearly 50,000 other related cancers in the UK, the British Public Health Agency said in a Bulletin released on the same day.
Mary Ramsay, head of immunization at the British Public Health Agency, said in a communique that full coverage of HPV vaccine gives us an opportunity to make HPV-related diseases a thing of the past based on the successful implementation of the girlsvaccination program. Vaccinating boys not only protects themselves, but also prevents girls from developing more HPV-related cancers, which will reduce the overall burden of these cancers on men and women in the future.
Our mathematical predictions and economic analysis fully support the inclusion of boys in the HPV vaccination program. Its cost-effective... Our work clearly shows how effective it is to continue vaccination programmes for girls, and the addition of boys will have additional protective effects against a range of cancers in both sexes.
HPV is believed to be responsible for more than 99% of cervical cancer, 90% of anal cancer, about 70% of vaginal and vulvar cancer, and more than 60% of penile cancer. More than 100 types of HPV are known, a few of which are high-risk, such as type 16 and 18 HPV, which cause about 70% of cervical cancer and precancerous lesions. HPV is mainly transmitted through sexual contact. Both men and women may be infected. Most carriers have no symptoms and are not easily detected.
The HPV vaccination programme was launched in 2008 in the UK, starting free vaccination for girls aged 12 to 13. According to guidelines posted on the official website of the National Health System, boys receive the same HPV vaccination procedure as girls. From September this year, all boys aged 12 to 13 will receive the first dose of vaccination and the second dose within 6 to 24 months. Teenagers who miss school vaccinations are free until they are 25 years old.
