BioNTech working to adapt its Covid-19 vaccine for Omicron variant

BioNTech is working to adapt its Covid-19 vaccine to address the Omicron variant and expects to have a new version ready within 100 days if necessary.

The company has started development to move as quickly as possible, BioNTech said in a statement. The first steps of developing a new vaccine overlap with the research necessary to evaluate whether a new shot will be needed — a process that began last Thursday as soon as news of the new variant began to spread around the world.

The German biotech and its Covid-19 vaccine partner Pfizer put plans into place months ago to ensure a new version of their shot could ship within 100 days if necessary. The omicron variant has raised concerns around the world, with countries implementing travel bans to buy time as researchers race to study whether it will evade vaccines and spread more rapidly. It will probably take weeks to understand the full impact of the variant, scientists have said.

Vaccinated people should still be protected, depending on how long ago they got their shots, and for now the best advice is to take one of the current Covid-19 vaccines, Moderna chief medical officer Paul Burton said on Sunday on the BBC’s “Andrew Marr Show.”
