BioNTech-Pfizer and Moderna vaccines 90% effective at preventing infections study shows

A study from the US Centers for Disease Control and Prevention (CDC) has shown that both BioNTech-Pfizer and Moderna vaccines are 90% effective at preventing infections, including asymptomatic infections, with the first dose showing 80% efficacy.

“Reducing the risk for transmissible infection, which can occur among persons with asymptomatic infection or among persons several days before symptoms onset, is especially important among health care personnel, first responders, and other essential and frontline workers given their potential to transmit the virus through frequent close contact with patients and the public,” the report concluded.
