New research has found that double vaccinated people were three times less likely than unvaccinated people to test positive for the coronavirus.
These results from the Imperial-led REACT-1 study, a major coronavirus monitoring programme, are based on swab tests taken by almost 100,000 people in England between 24 June and 12 July. During this period, 0.63% of people were infected, or 1 in 158. This represents a 4-fold rise compared with the study’s previous report, when 0.15% or 1 in 670 had the virus as of 7 June. These findings confirm our previous data showing that both doses of a vaccine offer good protection against getting infected. Prof Paul Elliott School of Public Health, Imperial
