(CNN) – Modern tests a new kind of COVID-19 booster.
It is a bivalent booster that combines an omicron-specific vaccine with the company’s original COVID-19 vaccine.
The company says there may be data for the booster sometime in March.
Pfizer has also been working on an omicron-specific vaccine and a bivalent vaccine, though FDA officials say it is unclear whether an omicron-specific vaccine will be needed.
Daily COVID-19 cases have dropped 90% in the U.S. since mid-January, according to new data from Johns Hopkins University.
