Pfizer confirm vaccine works against two mutant strains

The pharmaceutical giant Pfizer and researchers from the University of Texas have confirmed the Pfizer/BioNTech vaccine does protects against two new mutant variants.

In the new study, blood samples were taken from 20 people who received the Pfizer vaccine and it was found that the samples had neutralising levels of antibodies which worked against the new strains.

Pfizer has now confirmed it has tested 16 different mutations in the strains and none of them have had any significant impact on how the vaccine works. However, further studies are planned on other mutations.
