The Norwegian Medicines Agency has received several adverse event reports about younger vaccinated people with bleeding under the skin (tiny dots and /or larger blue patches) after coronavirus vaccination. This is serious and can be a sign of reduced blood platelet counts.

Who should seek medical attention?

People who have received the AstraZeneca vaccine and feel increasingly unwell more than three days after vaccination, and who notice larger or smaller blue spots in the skin (skin haemorrhages) must consult a doctor or out-of-hours medical service as soon as possible.

Notification of blood clots and brain haemorrhages after vaccination with the AstraZeneca vaccine

Yesterday, the Norwegian Medicines Agency and the Norwegian Institute of Public Health (NIPH) informed about an unexpected death from a brain haemorrhage in Tynset after vaccination with COVID-19 Vaccine AstraZeneca.

Today (March 13), we received three more reports of severe cases of blood clots or brain haemorrhages in younger people who have received the AstraZeneca vaccine. These are now receiving hospital treatment.

Common to these patients is that they have had a reduced number of blood platelets. Blood clots and subsequent brain haemorrhages are a rare condition.

- It has not been concluded that there is any link between the vaccine and these cases , but due to the seriousness, these cases are being thoroughly investigated. We ask healthcare professionals to be aware of these symptoms after vaccination, says Steinar Madsen, medical director at the Norwegian Medicines Agency.

Similar cases in other countries

Similar incidents have been reported in other European countries, and the European Medicines Agency (EMA) is considering whether there may be an association with the coronavirus vaccines. So far, no conclusion has been reached.

Looking closely at side effects with reports of blood clots and haemorrhages

The NIPH and the Norwegian Medicines Agency have initiated analyses to investigate the association between the vaccine and various forms of blood clots, such as stroke and blood clots in the lungs. These analyses will take time.

The Norwegian Medicines Agency will now look extra closely at reports of blood clots and bleeding for all coronavirus vaccines. We ask healthcare professionals who suspect side effects after vaccination to report them as soon as possible.

The European Medicines Agency (EMA) has also launched its own investigations into the vaccine.

How to report side effects

Healthcare professionals are obliged to report suspected new, unexpected and severe side effects. The staff at NIPH is increased and RELIS is assisting NIPH in handling notifications so they can be processed faster.
Members of the public can report side effects via, but are encouraged to contact a doctor or other healthcare professional if they suspect severe or unexpected side effects after vaccination.
