The vaccination break in the United States that applies to the corona vaccine from pharmaceutical company Johnson & Johnson has been extended for one week.
An expert panel from the American Center for Disease Prevention (CDC) says it will take more time to assess the possible link between the vaccine and rare cases of blood clots.
The CDC panel met a day after US authorities reported that six women developed blood clots in the brain and low platelet count within two weeks of administering the Johnson & Johnson vaccine. One of the women died of the consequences.
The vaccine, developed by the biotechnology company Janssen from Leiden, has already been administered to 7.2 million Americans. When the panel met on Wednesday, members were informed that a seventh blood clot case has now been found in one of the vaccinees, a 28-year-old woman.
The panel could have decided on Wednesday to only give the Janssen vaccine to specific age groups with a low risk of health damage, but most panel members want to see more data before making such a choice.
The next meeting of the CDC panel is not yet scheduled but is expected within a week to 10 days.
