Moderna reported yesterday that its COVID-19 vaccine offers protection against variants of the virus that are being reported. Last week, Pfizer and BioNTech announced that their COVID-19 vaccine was probably just as effective against the variant strain of the virus, B.1.1.7, found in the U.K. The variant was believed to have emerged in the U.K. in September 2020 and is noted to be more infectious, and possibly more deadly. British scientists suggested last week that the U.K. variant may be approximately 30% more lethal than the most common strain that came out of China. But they’re not completely sure of this yet.
