Moderna has ramped up efforts to make a booster vaccine to combat new corona variants, including Omicron.
As the virus evolves, vaccine makers have started efforts to combat the new strain by designing and testing new booster shots. Moderna has announced a three-pronged strategy to address SARS-CoV-2 variants of concern and is working on a new variant-specific vaccine candidate against Omicron. It tests adults with a higher dose of 100 µg dose of mRNA-1273 to determine if it can provide higher immunogenicity against the new variant. The company has said that if a new vaccine is to be made, it will be ready by early 2022.
