FDA Pfizer Vaccine Storage Update

FDA Pfizer Vaccine Storage Update

On May 19th, the FDA announced the Pfizer COVID-19 Vaccine can now be stored at normal refrigerator temperatures for up to a month (30 days). This is much longer than was previously allowed under the FDA’s emergency authorization and will make storage and distribution of the vaccine easier.

The FDA is now authorizing undiluted, thawed Pfizer-BionTech COVID-19 vaccine vials to be stored in the refrigerator at 2°C to 8°C (35°F to 46°F) for up to 1 month (30 days). Previously, thawed, undiluted vaccine vials could be stored in the refrigerator for up to 5 days.

The FDA says the change should make the vaccine more widely available by making it easier for doctors’ offices to receive, store and administer the vaccine. “Making COVID-19 vaccines widely available is key to getting people vaccinated and bringing the pandemic to an end,” says Dr. Peter Marks, director of the FDA’s Center for Biologics and Research. PDPH hopes that this change will help providers vaccinate more patients in Philadelphia.
