FDA has authorized 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 one month. This is a change from previous guidance which stated that thawed, undiluted vaccine vials could be stored in the refrigerator for up to five days. See the factsheet for healthcare providers administering vaccine for more information. This will make it easier for doctors offices to order and administer the Pfizer vaccine.
