“The study by Pfizer and scientists from the University of Texas Medical Branch, which has not yet been peer-reviewed, indicated the vaccine was effective in neutralizing virus with the so-called N501Y mutation of the spike protein.”
Good news, from the company that sells the vaccine. The study is Pfizer’s own lab work and nobody has peer-reviewed it. The mutation that worries Pfizer’s own scientist, E484K in the South African variant, wasn’t in this test. Believe it when someone without a stake confirms it.
