At the moment, two- or three-dose regimens are recommended, but the WHO's Strategic Advisory Group of Experts on Immunization said the evidence showed that one dose was 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.
