US FDA advisers meet to discuss design of future Covid vaccines

Outside advisers to the US Food and Drug Administration are meeting on Tuesday to discuss whether to change the design of Covid-19 vaccines in order to combat future variants of the coronavirus.

The updated shots are likely to be redesigned to fight the Omicron variant of the coronavirus, experts say. The exact composition of the retooled shots and whether they also will include some of the original vaccines alongside new components will be considered at the meeting.
