The Food and Drug Administration extended the shelf life for the Johnson & Johnson single-dose vaccine, pushing back the expiration date by six weeks. The Pennsylvania Department of Health says it had over 6,700 doses of Johnson & Johnson that were set to expire by the end of June, but due to the extension, those doses can be used through August 7.
