During the dialogue, although, questions arose in regards to the June goal date. Given the manufacturing schedule for some vaccines, that date would possibly must shift, stated Jerry Weir, PhD, director of the division of viral merchandise at FDA’s Center for Biologics Evaluation and Research.
“We’re all simply going to have to take care of flexibility,” Weir stated, including that there’s not but a “good sample” established for updating these vaccines.
