Coronavirus infections three times lower in double vaccinated people [Imperial College London news report.] People who were unvaccinated had a three-fold higher prevalence than those who had received both doses of a vaccine, at 1.21% compared to 0.40%. However both of these represent more than a five-fold increase compared to the previous round (0.24%, 0.07%, respectively). Based on these data, the researchers estimate that fully vaccinated people in this testing round had between around 50% to 60% reduced risk of infection, including asymptomatic infection, compared to unvaccinated people. In addition, double vaccinated people were less likely than unvaccinated people to test positive after coming into contact with someone who had COVID-19 (3.84% vs 7.23%).
