BioNTech SE said on Friday it expects more data on a worrying new coronavirus variant detected in South Africa within two weeks to help determine whether its vaccine produced with partner Pfizer Inc would have to be reworked.
Pfizer and BioNTech said that if necessary they expect to be able to ship a new vaccine tailored to the emerging variant in approximately 100 days.
"We understand the concern of experts and have immediately initiated investigations on variant B.1.1.529," BioNTech said in a statement when asked to comment.
"We expect more data from the laboratory tests in two weeks at the latest. These data will provide more information about whether B.1.1.529 could be an escape variant that may require an adjustment of our vaccine if the variant spreads globally," it added.
Moderna Inc said in a statement it is working to advance a booster candidate tailored to the new variant and has also been testing a higher dose of its existing booster and to study other booster candidates designed to protect against multiple variants.
