XBB.1.5 strain as soon as JulyInc. said it’s capable of making shots targeting Covid-19’s XBB.1.5 strain by the end of July if government regulators recommend it, while another version under consideration would take longer.
Pfizer and its partner BioNTech SE would need until August to deliver a vaccine targeting the other strain, called XBB.1.16, Kena Swanson, Pfizer’s vice president for viral vaccines, said Thursday at a meeting of US Food and Drug Administration vaccine advisers.
The panel of outside experts is gathering to vote on a recommendation for formulating Covid vaccines to be distributed later this year.
The vaccines have been designed to fight the original strain that was first seen in Wuhan, China. However, the latest data suggest that shots targeting a single strain of XBB, a version of the highly infectious omicron variant, would be most effective, according Pfizer’s company’s presentation.
