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.
