AstraZeneca delays filing for US authorization of COVID shot
LONDON — AstraZeneca said Friday that it intends to seek U.S. authorization for its COVID-19 vaccine in the “coming weeks,” acknowledging a delay in the much-anticipated filing that had been expected by mid-April.
The Anglo-Swedish drugmaker revealed the new timetable as it released first-quarter financial results, which showed that the company delivered 68 million doses of the vaccine to the U.K., European Union and other countries in the first three months of the year.
The company said it was continuing to work on its application to the U.S. Food and Drug Administration, noting the “substantial size of the file” that will include data from U.S. trials as well all other studies completed so far and real-world data collected from use of the vaccine in other countries.
Among the issues that will likely be addressed are indications that the vaccine is linked to rare blood clots, particularly in younger people. Several countries have recommended that the shot be given only to older people because of the potential side effect. Vaccine experts say the blood clots are very rare, less than the blood clot risks of women taking birth control.
