TNI Bureau: Pfizer and its German partner BioNTech have claimed that their vaccine seems to be effective against the new mutation that have spread widely in Britain, UK. The new mutation has increased the transmissible rate of the virus amongst the human.

There was an air of speculation that the vaccine may not be effective against the virus. The new mutation may result in escaping the antibody neutralisation produced by the vaccine. However, one of the top experts of Pfizer’s vaccine, Phil Dormitzer, said that the vaccine has been effective against 16 mutations. He further added that the study was conducted on the blood samples taken from the vaccinated people. The results are limited as it does not reflect upon the full set of mutation found in the new variants.
