A walk-in Covid vaccination clinic is to be held at Downham Market Town Hall on Sunday from 9am to 2pm.
No appointment is needed for people in the priority groups who have not had their first jab.
A Norfolk and Waveney Clinical Commissioning Group spokesman said those in priority groups under the age of 30 could not attend the walk-in clinics due to changes in national guidance.
If you had your first vaccination at a GP site or hospital hub, you will be contacted for your second dose.
People who booked via the national booking system should already have a second dose date.
On Wednesday the government announced people over the age of 45 were now eligible for the vaccine and can book via www.nhs.uk/coronavirus or call 119 or via their GP practice.
