The Cliffs Pavilion in Southend will open as a Covid-19 mass vaccination centre this week.
The theatre is one of six new vaccine sites opening across Essex and Suffolk as the NHS rapidly accelerates the number of places it can give the crucial first dose of the vaccine.
Rochford and Southend East MP James Duddridge welcomed the announcement.
The Cliffs will have the capacity to vaccinate hundreds of people a day and thousands of people each week.
Those in the top four priority groups - including people aged 70 years old and over, and those who are clinically extremely vulnerable - are being invited to book an appointment at the vaccination centres through the national booking service.
The centres will also be vaccinating health and care staff who are being urged to get their first dose as soon as possible to protect themselves and others.
The six new large-scale vaccination centres planned to go live over the coming week:
- Chelmsford City Racecourse
- Colchester United Jobserve Community Stadium
- The Cliffs Pavilion, Southend-on-Sea
- Former Riverwalk School, Bury St Edmunds
- Clacton Hospital
- Alastair Farquharson Centre, Thurrock Community Hospital
