Yes.
The National Advisory Committee on Immunization—and Dr. Matthew Tunis is here with us—made a recommendation to preferentially use the bivalent vaccine, both Moderna and Pfizer now that we have them, because it contains both the original virus strain and the omicron variant strain. That helps not only to boost your antibody level when you get the booster—if you haven't had it in the last six months, go get one—but to broaden the repertoire of your immune response.
It does more than just boost levels of antibodies. The way that these bivalent vaccines are constructed, we believe it will increase the repertoire of the immune response itself.
