“The study published by the U.K.’s Office of National Statistics (ONS) looked at more than 8,000 positive coronavirus tests across Britain between May and August, when delta was the dominant variant.”
“During this time, people who had previously recovered from Covid-19 were about 71% less likely to contract it a second time, the analysis found.”
“The overlap in confidence intervals meant there “was no evidence” that full vaccination was any more effective in preventing Covid-19 than previous natural infection, the researchers concluded.”
