Brief19: Coronavirus MRNA Vaccines Reduce The Risk Of Asymptomatic Infection

Brief19: Coronavirus MRNA Vaccines Reduce The Risk Of Asymptomatic Infection. “This research, conducted by the Mayo Clinic health system across its hospitals in Minnesota, Arizona, and Wisconsin, recruited patients requiring covid-19 testing 48 to 72 hours ahead of planned procedures and surgeries. The patients were divided into two cohorts: those who had received at least one dose of either vaccine and those who hadn’t had a shot yet at the time of the testing. Of the nearly 40,000 patients who were tested, 3.2 percent of the unvaccinated group tested positive, while only 1.4 percent of the protected group was found to have contracted SARS-CoV-2. This was a statistically notable difference and suggests a relative risk reduction of 44 percent after getting vaccinated for asymptomatic disease.”
