Vaccines the Cause of Britain’s Drop In Covid Cases, Not Lockdown, Says KCL Epidemiologist

A King’s College London epidemiologist has said that Britain’s “exemplar vaccine programme” – which has seen almost 40 million first and second doses administered – is behind the drop in Covid cases since January. Professor Tim Spector’s view contrasts with that of the Prime Minister who believes lockdown – not the vaccine – has delivered “this improvement in the pandemic“. The Mail has the story.

Vaccines are behind Britain’s sharp drop in coronavirus cases since January, top experts claimed today – despite Boris Johnson insisting lockdown was the reason for the fall.  

Professor Tim Spector, a King’s College London epidemiologist who runs the UK’s largest Covid symptom tracking study, said the epidemic had “mainly” been squashed by the “exemplar vaccine programme”.

With more than 60% of the population jabbed with at least one dose and up to 10% protected due to prior infection, Professor Spector added Britain was “starting to see herd immunity take effect”.

His comments come after data from his symptom-tracking app showed a 17% drop in daily cases last week, with an estimated 1,600 new symptomatic infections a day across the country – down from 60,000 at the peak in January.

Separate Test and Trace figures showed new cases in England had dipped by 34% last week, with 19,196 positive tests recorded in the seven days to April 7th – compared to 29,178 at the end of March. 

Professor Spector said: “As the UK slowly exits lockdown, I’m encouraged to see Covid cases continue to fall with our rates among the lowest in Europe. 

“In fact, the UK closely mirrors cases in Israel with its exemplar vaccine programme. Based on our data and countries like Israel, I believe the fall in cases since January is mainly thanks to the vaccination programme and less about the strict lockdown the UK has been under since late December. 

“With up to 60% of the population vaccinated and around five to 10% with natural immunity due to infection, we’re starting to see herd immunity take effect. This should prevent future large-scale outbreaks.”

Professor Spector warned it was inevitable cases would pick up again as restrictions are eased over the coming months. But he said any outbreaks would be “smaller” and “manageable” and among groups yet to be vaccinated.

The Prime Minister has been underplaying the impact of the vaccine for some weeks. As well as pinning the fall in Covid cases on lockdown rather than on the vaccine rollout, he recently said that vaccinated people must not meet indoors because jabs “are not giving 100% protection” – this despite the fact that the risk of catching a symptomatic Covid infection for two people who have been vaccinated is about one in 400,000. His confidence in lockdowns has, however, stood firm, despite an increasing number of studies showing they’re ineffective.
