Professor Tim Spector OBE, lead scientist on the ZOE COVID Symptom Study app and Professor of Genetic Epidemiology at King’s College London said: “The data should reassure many people that in the real world, after-effects of the vaccine are usually mild and short-lived, especially in the over 50’s who are most at risk of the infection.
“Rates of new disease are at a new low in the UK according to the ZOE app, due to a combination of social measures and vaccination and we need to continue this successful strategy to cover the remaining population.
“The results also show up to 70 percent protection after three weeks following a single dose, which is fantastic news for the country, especially as more people have now had their second jabs.”
But, crucially, the total number of side effects in the general public were fewer than seen in the initial clinical trials for the vaccine.
