Scotland has “limited supplies” of the vaccine used to protect against monkeypox amid a steady increase in cases.
Ten new cases of the condition have been reported across the country over the past two-and-a-half weeks, taking the total number to 79.
Public Health Scotland (PHS) has warned a “limited global supply” of the smallpox vaccine, which is also used to treat the disease, means stocks are low worldwide.
However the health body said work was under way to boost quantities.
Medical director Dr Nick Phin said: “As we know, there is a limited global supply of the smallpox vaccine which offers protection against monkeypox, and remaining available doses are being administered at pace in Scotland as this gives the greatest opportunity to contain spread while numbers are still relatively small.
“PHS continues to work with colleagues across the UK to ensure additional vaccinations are available, and is closely following the work of the pilot sites in England looking at the use of intradermal administration of the vaccine.”
PHS experts also stressed that “most cases in Scotland are in men who are gay, bisexual or have sex with men” and “primarily associated with recent travel to London or Europe”.
Dr Phin encouraged those who believe they are at risk to get vaccinated as soon as possible.
He said: “If you are currently unvaccinated, please ensure you are aware of the signs and symptoms, take steps to reduce your risk of exposure to monkeypox and seek medical advice if you think you may have the infection.”
PHS has previously said anyone with an unusual blister-like rash or small number of blister-like sores on any part of their body, including their genital area, should avoid close contact with others and seek medical advice via telephone if they have any concerns.
