Middlesbrough Football Club Foundation's bus has been converted into a vaccine centre to encourage more young people to get a Covid jab.
It is offering appointment-free slots on Tuesday and Wednesday to try to lower Redcar and Cleveland's virus rates, which are the highest in the UK.
The charity's bus has been parked up at the Asda store in Skelton in a bid to attract as many under 40s as possible.
Across the borough there are 18,500 adults who have not had a single jab.
Leader of Redcar and Cleveland Council Mary Lanigan said: "What the young people have got to understand - and what we've got in East Cleveland with the 18 to 39-year-olds - [is that] there's only 50% that have had a vaccination.
