Welcome to the official website of the Government of Saint Vincent and the Grenadines.

The United States Food and Drug Administration (USFDA), has approved a request from Pfizer, Inc. to extend the shelf-life of the Pfizer COVID-19 vaccine for an additional three months - from six to nine months - when the vaccine is stored at a temperature of -90 to -60 degrees celsius.

On August 22, 2021 the USFDA issued a concurrence letter approving Pfizer Inc’s request, and on August 23, 2021, the agency revised the Fact Sheet for healthcare providers Administering Vaccines to provide updates on expiration dates for the authorised Pfizer-BioNTech COVID-19 Vaccine.

According to the fact sheet, cartons and vials of Pfizer COVID-19 Vaccine with an expiry date of August 2021 through to February 2022 printed on the label may remain in use for 3 months beyond the printed date, as long as approved storage conditions between -90 degrees celsius to -60 degrees celsius have been maintained.
