Pfizer's COVID-19 Vaccine Slightly Less Effective Against Key South African Mutations, Study Shows
📝@COVID19Up: Pfizer Inc and BioNTech’s COVID-19 vaccine appeared to lose only a small bit of effectiveness against an engineered virus with three key mutations from the new coronavirus variant found in South Africa, according to a laboratory study conducted by the U.S. drugmaker.
The study by Pfizer and scientists from the University of Texas Medical Branch, which has not yet been peer-reviewed, showed a less than two-fold reduction in antibody titer levels, indicating the vaccine would likely be effective in neutralizing a virus with the so-called E484K and N501Y mutations found in the South African variant.
The study was conducted on blood taken from people who had received the vaccine. Its findings are limited because it does not look at the full set of mutations found in the new South African variant. SOURCE
