Federal health regulators have again extended the expiration dates on Johnson & Johnson’s COVID-19 vaccine by another six weeks.
Federal health regulators once again extended the expiration dates on Johnson & Johnson’s COVID-19 vaccine, providing health workers with six more weeks to use millions of doses of the shot.
The Food and Drug Administration said in a letter to J&J that the shots remained safe and effective for at least six months when properly stored and refrigerated. Wednesday’s action was the second time the FDA hadsince June, when the agency said they could be used for up to 4½ months. When first authorized in February, the FDA said the vaccines could be stored for three months at normal refrigeration levels.
Health authorities in many states recently warned that they could be forced to throw out thousands of doses of the one-shot vaccine without an extension.The change gives health providers more time to use remaining shots sitting at pharmacies, hospitals and clinics. After plateauing earlier this summer,again as the highly transmissible Delta variant of the coronavirus surges across many parts of the country.
Vaccine expiration dates are based on information from drugmakers on how long the shots stay at the right strength. J&J previously stated that it continued to conduct stability testing with the aim of further extending the shelf life of the shots.
