The smallpox vaccine used for monkeypox will be offered in smaller doses in efforts to stretch limited supplies.
Three NHS sites will begin administering 'fractional doses' to space out the constrained number of doses in a method that will protect up to five times more people.
Under the approach, eligible people aged 18 and over will be offered a 0.1ml dose of the smallpox Jynneos vaccine, instead of the 0.5ml dose which is typically administered for monkeypox.
