A comprehensive study conducted by the University of Texas Medical Branch (UTMB) suggests that the Pfizer vaccine is still effective against the COVID-19 mutation found in South Africa.
The results do not indicate a potential need for formulating a new vaccine and are pending further scrutiny by relevant authorities.
As per reports, tests were conducted on blood samples extracted from patients who had been vaccinated. The researchers observed less than a two-fold decrease in their antibody counts, therefore, indicating that more doses of the vaccine periodically would neutralize the so-called E484K and N501Y COVID-19 mutations.
The research team leading the study is currently experimenting with a full set of mutations and plans on arriving at definitive results in the coming weeks.
Team lead, Pei Yong Shi, who is also a professor at UTMB, said in a statement that the experiment also reveals promising results against the highly transmissible UK variant of the virus. Shi added the team is working on a full set of mutations from that variant as well.
Although these findings do not indicate much, Pfizer and BioNTech are well equipped to respond if a SARS-CoV-2 mutation shows evidence of evading the vaccine.
