Washington (AP) — Johnson & Johnson said Thursday that US regulators have extended the expiration date of millions of COVID-19 vaccines by six weeks.
The company said a Food and Drug Administration review concluded that Shot was safe and effective for at least four and a half months. In February, the FDA initially approved the J & J vaccine for up to three months when stored at normal refrigerated levels.
The announcement on Thursday will come after state officials warn that many doses in storage will expire by the end of the month.
Vaccine expiration is based on information from pharmaceutical companies about how long shots stay at the right intensity. 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 continue to test batches for months after Shot was first deployed. The Pfizer and Modana vaccines approved in December are valid for 6 months.
J & J expansion helps maintain vaccine supply even if the number of Americans firing is reduced. The country made an average of about 800,000 new injections per day last week. This is down from a high of nearly 2 million shots per day two months ago. Government officials and businesses are looking to incentives to encourage shots, such as paid vacations for a $ 1 million lottery prize.
Due to the delay in vaccination, it has become clear that the United States is unlikely to meet President Joe Biden’s goal of partially immunizing 70% of adults by July 4. Control and prevention.
J & J’s vaccine was highly anticipated due to its one-time prescription and easy-to-ship refrigeration. The shot was expected to play an important role in vaccination campaigns in rural areas and low-income countries where medical infrastructure is limited.
However, rival pharmaceutical companies Pfizer and Moderna, which began shipping shots a few months ago, have already supplied enough to meet US demand. Over 129 million Americans have been fully vaccinated with two company vaccinations. By comparison, only 11 million Americans have been vaccinated with J & J Shots. According to the CDC, about 10 million more J & J doses were sent to the state.
The use of J & J vaccines has been hurt by the association with rare thrombotic disorders. Due to this issue, US health officials have “suspended” the use of shots for an 11-day review. Authorities lifted the hold in late April after concluding that the benefits of the vaccine outweigh the risks.
J & J’s deployment has also been slowed down by pollution issues at the Baltimore plant, which helps to create shots. The facility was closed after an FDA examination revealed unsanitary conditions and other problems in April. None of the vaccines made there have been distributed.
