Norway and Denmark have temporarily suspended the use of the AstraZeneca vaccine.
Both countries say it's over concerns about patients developing post-jab blood clots.
The manufacturer and the European Medicines Agency insist the vaccine is safe.
Meanwhile, the use of the AstraZeneca vaccine for the 70s and older has been approved for use here.
The National Immunisation Advisory Committee has updated its advice which previously stated that the vaccine should not be given to anyone over 65.
