A former footballer joined vaccination volunteers at a football ground as adults in England were offered the chance to "grab a jab".
Ex-Watford and England striker Luther Blissett encouraged over-18s to take the Pfizer vaccine at the "Super Sunday" clinic.
More than 1,000 people were vaccinated at Watford's Vicarage Road stadium.
Blissett said people had a "moral responsibility" to do as they were asked and protect the vulnerable.

The Pfizer vaccine is being offered to over-18s yet to receive their first jab, and to other age groups who can show they are awaiting their second.
