Now that the Moderna and Pfizer-BioNTech coronavirus vaccines have been utilized in millions of people for a few months now, health professionals are looking at actual real-world data which shows both are indeed highly effective at preventing COVID-19 infections.
From the New York Times:
Consistent with clinical trial data, a two-dose regimen prevented 90 percent of infections by two weeks after the second shot. One dose prevented 80 percent of infections by two weeks after vaccination.
There has been debate over whether vaccinated people can still get asymptomatic infections and transmit the virus to others. The study, by researchers at the Centers for Disease Control and Prevention, suggested that transmission may be extremely unlikely, as infections were so rare.
There also has been concern that variants may render the vaccines less effective. The study’s results do not confirm that fear. Troubling variants were circulating during the time of the study — from December 14, 2020 to March 13, 2021 — yet the vaccines still provided powerful protection.
In related news, President Biden will announce today that 90% of adults will be eligible to get a coronavirus vaccine within the next three weeks, which moves up his earlier deadline. Plus, the number of pharmacies distributing the vaccines will double soon.
