Just one dose of the Moderna and Pfizer two-shot coronavirus vaccines is seemingly nearly as good two.
In a study published Thursday in the New England Journal of Medicine, a pair of Canadian-based researchers suggested an amendment to the determined efficacy of the Pfizer vaccines after just one shot. While Pfizer and BioNTech reported their vaccine was just 52.4 percent effective at preventing infection after the first dose, the researchers noted that this data includes results from within the first two weeks after inoculation, “when immunity would have still been mounting.” After two weeks, that efficacy mounted to 92.6 percent, matching the first-dose efficacy of 92.1 percent reported from the Moderna vaccine as well. After two doses, the Pfizer vaccine is 95 percent effective, and Moderna’s is 94 percent.
