Gonorrhoea vaccines will be widely available from today in sexual health clinics across the UK, in a bid to tackle record-breaking levels of infections.
The jabs will first be offered to those at highest risk - mostly gay and bisexual men who have a history of multiple sexual partners or sexually transmitted infections.
NHS England say the roll out is a world-first, and predict it could prevent as many as 100,000 cases, potentially saving the NHS almost £8m over the next decade.
The Terrence Higgins Trust, who campaigned for the vaccine to be introduced in the UK, told the BBC it was "a huge win" for sexual health.
Gonorrhoea is a bacterial infection that is transmitted through unprotected sex.
