Denmark on Wednesday became the first country to plan to permanently stop administering the AstraZeneca vaccine, a month after suspending its use following reports that a small number of recipients had developed a rare but serious blood-clotting disorder.
The director general of the country’s health authority, Soeren Brostroem, said Denmark was able to halt use of the vaccine because it had the pandemic under control and could rely on two other vaccines, from Pfizer and Moderna.
The Danish announcement is another setback for the AstraZeneca shot, which is easy to store and relatively cheap, and was expected to be the foundation of vaccination campaigns around the world.
The country initially suspended the use of the vaccine on March 11, along with Iceland and Norway. Several other European countries, including France, Germany and Italy, followed suit last month.
later recommended that countries keep using the vaccine, saying its benefits far outweighed any potential risks for most people.
Last week, though, the European regulator listed blood clots as a potential very rare side effect of the vaccine.
Several countries that had paused and restarted use of the vaccine have since said they would stop using it in younger people. Britain, which has administered around 20 million AstraZeneca doses, said it would offer alternative vaccines to people under 30.
“Based on the scientific findings, our overall assessment is there is a real risk of severe side effects associated with using the Covid-19 vaccine from AstraZeneca,” Dr. Brostroem, the Danish health official, said in a statement. “We have, therefore, decided to remove the vaccine from our vaccination program.”
“If Denmark were in a completely different situation and in the midst of a violent third outbreak, for example, and a health care system under pressure,” he added, “then I would not hesitate to use the vaccine, even if there were rare but severe complications associated with using it.”
