Throughout the dialogue, although, questions arose in regards to the June goal date. Given the manufacturing schedule for some vaccines, that date may must shift, mentioned Jerry Weir, PhD, director of the division of viral merchandise at FDA’s Middle for Biologics Analysis and Analysis. 

“We’re all simply going to have to take care of flexibility,” Weir mentioned, including that there’s not but a “good sample” established for updating these vaccines.
