Vaccine expiration dates are based on information from pharmaceutical companies about how long an injection will maintain its proper strength. J & J said the FDA added 6 weeks based on data from an ongoing study assessing vaccine stability.
The FDA is considering the expiration dates for all three US-approved vaccines as companies have been testing batches for several months since the vaccine was first released. The Pfizer and Moderna vaccines approved in December have a shelf life of 6 months.
J & J’s extensions help maintain a supply of vaccines even when the number of Americans vaccinated decreases. Last week, the country received an average of about 800,000 new injections per day.

According to the CDC, about 10 million more J & J doses were sent to the state.
J & J’s vaccine use has been hit by a rare association with thrombotic disorders. Due to this issue, US health officials “Pause” the use of shots for an 11-day reviewAuthorities lifted the hold in late April after concluding that the benefits of the vaccine outweigh the risks.
J & J’s deployment has also been delayed by pollution issues at its Baltimore factory, which is useful for filming. The facility was closed after an FDA examination revealed unsanitary conditions and other problems in April. Vaccines made there are not distributed.
