Queues stretched back across Westminster bridge by daybreak as people waited in line for a booster at St Thomas’s hospital.

It came as all bookable slots for the next five days at the Science Museum, in South Kensington, were snapped up in advance of its reopening on Wednesday.

However the museum, used by the Duke and Duchess of Cambridge to get inoculated, will accept walk-ins – though long queues are expected and people with a booking will be prioritised.

Guy’s and St Thomas’s NHS trust said it administered 3,500 jabs yesterday, including first and second doses – of which about 2,000 were given at its two vaccine hubs at St Thomas’s.

West Middlesex and Hillingdon hospitals became the latest to open vaccination centres, with Gordon hospital, in Pimlico, also offering jabs.

Demand will further increase on Wednesday when the NHS booking system opens to the 18-29 age group – adding to the need for volunteer vaccinators to return to the front line.

St John Ambulance trained 30,000 volunteers, including 20,000 vaccinators, earlier this year and is asking them to help again.
