..."Pfizer and BioNTech also report that they expect to start a human study on the safety and immunogenicity of the BA4/BA5 bivalent vaccine this month.
Earlier this year, vaccine makers presented U.S. and European regulatory authorities with an option for a bivalent vaccine that targeted an earlier version of the omicron variant, BA.1. While the plan was accepted in the U.K., U.S. regulators instead asked the companies to update the vaccines to target the newer subvariants.
Scientists say the development of COVID-19 vaccines may go the way of flu vaccines, which are changed every year to try to match the strains that are likely to be circulating."
