LONDON (Reuters) - A single dose of human papillomavirus (HPV) vaccine is enough to protect against cervical cancer, a World Health Organization group of experts has said.

At the moment, two- or three-dose regimens are recommended, but following a meeting on immunization pratices last week (, the WHO's Strategic Advisory Group of Experts on Immunization said the evidence showed one dose is as effective.

"This could be a game-changer for the prevention of the disease; seeing more doses of the life-saving jab reach more girls," the WHO said in a statement.
