U.S. FDA extends shelf life of Johnson & Johnson COVID-19 vaccine
Johnson & Johnson said on Thursday the U.S. Food and Drug Administration has extended the shelf life of its single-shot COVID-19 vaccine from three months to four-and-a-half months, as millions of unused doses nationwide near expiration.

Safety concerns about J&J s shot and flagging demand for vaccinations have left close to half of the 21 million doses the company has produced for the United States sitting unused.

The health regulator s decision was based on data from ongoing studies, which demonstrated that the vaccine is stable at 4.5 months when refrigerated at temperatures of 36 to 46 degrees Fahrenheit (2 to 8 degrees Celsius), the drugmaker said.

Reuters reported on Monday that at least 13 lots of J&J shots have expiration dates of June 27 or earlier. It is not clear how many doses that reflects. J&J has another 100 million doses on hand but shipment timing is uncertain.

A top White House official on Tuesday urged state governors to work with the FDA to extend the shelf life of J&J s COVID-19 vaccine.

J&J said vaccine providers should visit its website to check expiration dates of vaccines currently available in the country.
