Novavax Inc said on Thursday it could begin commercial manufacturing of a Covid-19 vaccine tailored for the Omicron coronavirus variant in January next year, while it tests whether or not its current vaccine works against the variant.
Laboratory data expected in the coming weeks will show whether antibodies from individuals who have previously received Novavax's Covid-19 shot can neutralise the variant, according to the company.
Novavax also said it has started developing an Omicron-specific spike protein antigen and will begin laboratory tests of a new vaccine to target the variant in a few weeks.
The Omicron coronavirus variant has shaken up markets and caused global alarm over concerns about whether it could evade protection provided by widely used vaccines and prolong the public health crisis.
Other vaccine makers including Moderna and Pfizer have also begun working on Omicron-tailored Covid-19 shots.
Novavax's Covid-19 vaccine received its first emergency use approval in Indonesia in early November followed by the Philippines.
