In comparison, men and women in the same age team experienced a 2.9-fold increase in antibodies one particular month subsequent administration of the primary vaccine.
In folks age 18-55, the bivalent booster led to a 9.5-fold enhance in antibodies. Pfizer and BioNTech failed to supply a comparison for that age group following acquiring the unique vaccine. So, the advantage for younger older people is significantly less crystal clear.
Right now, the BA.5 sub-variant even now leads cases in the U.S., accounting for additional than 39%. But BA.4 accounts for much less than 1% of all circumstances. In the meantime, the more recent BQ.1 and BQ.1.1 sub-variants are climbing in the circumstance rankings.
