Girls aged 12 to 13 are offered the jab to help protect them from cervical cancer as part of the NHS childhood vaccination programme.
But girls can opt out and boys are not entitled to it – leaving them at risk of catching the virus from an unvaccinated partner during oral or penetrative sex.
“Only a gender neutral vaccination programme can offer all our children the best defence.” Mary Ramsay, head of immunisation at Public Health England, said: "Evidence from around the world suggests that the risk of HPV infection in males is dramatically reduced by achieving high uptake of the HPV vaccine among girls.
"While there are some additional benefits to vaccinating both males and females, the current models indicate that extending the programme to boys in the UK, where the uptake in girls is consistently high, would not represent a good use of NHS resources." HPV is linked to cervical, vulval, vaginal, penile, anal, head and neck cancers.
The Joint Committee on Vaccination and Immunisation, which advises health officials on immunisation, considered widening the programme to include boys.
