BioNTech's CEO
says he is confident the vaccine will work against a new strain of COVID-19.
The virus
variant has been found in the United Kingdom and other countries.
CEO Uğur Şahin
says he has confidence in the Pfizer vaccine because "the proteins on the
variant are 99% the same as the prevailing strains."
He says further
studies are needed to be completely sure.
Moderna says it
believes its vaccine would protect against the mutation but they are also doing
additional tests to confirm that.
COVID-19 has mutated
before and both companies say their vaccines worked against those variations.
