The U.S. Food & Drug Administration (FDA) has authorized an extension of the shelf life for the Johnson & Johnson single-shot COVID-19 vaccine from 3 months to 4.5 months, according to a news release from the company.
Johnson & Johnson says decision is based on data from ongoing stability assessment studies, which have demonstrated that the vaccine is stable at 4.5 months when refrigerated at temperatures of 36 – 46 degrees Fahrenheit (2 – 8 degrees Celsius).
