The American pharmaceutical company said on Thursday that Johnson & Johnson’s vaccine against covid-19 can now be refrigerated in the United States for four and a half months instead of three months.
This change is urgently needed in the country because it extends the shelf life of hundreds of thousands of doses, which may expire soon if they are not used.
According to Johnson & Johnson, the extension has been approved by the U.S. Drug Administration (FDA).
Johnson & Johnson said in a statement: “The decision is based on data showing that if stored at 2 to 8 degrees Celsius, the vaccine is stable after 4.5 months.”
According to the US Centers for Disease Control and Prevention (CDC), more than 21 million doses of the vaccine have been distributed to US states, and only more than 11 million doses have been consumed.
On Monday, Ohio Governor Mike DeWine warned that the June 200 expiration date for the 200,000 doses of Johnson & Johnson vaccine in his state will expire.
He called on residents of his country to get vaccinated as soon as possible, and criticized the lack of legal possibilities for sending these vaccines to other states or abroad.
Due to the small number of women with severe thrombosis and low platelet counts, Johnson & Johnson suspended vaccination for 10 days in April.
Health authorities ultimately estimate that the benefits of vaccination outweigh the risks.
