All reports of suspected adverse drug reactions, regardless of whether they are reported by healthcare professionals or patients or received from vaccine manufacturers, end up in the Norwegian ADR Registry.

The weekly updates summarize all suspected adverse reactions that have been assessed and processed.

The adverse reaction reports are assessed on a continuous basis. Reports of suspected serious adverse reactions are prioritized for assessment. The weekly updates will therefore give a skewed picture of the distribution between serious and nonserious reports.

The adverse reaction statistics for the different covid-19 vaccines are not directly comparable because they have not been used in the covid vaccination program for the same length of time, and because the vaccines are administered to different numbers of people and to different age groups.

Adverse reactions are reported on suspicion and the reports describe events that have occurred after vaccination. Even though an event has been reported, this does not necessarily imply that a causal relationship has been established between the event and the vaccines. The known adverse reactions of the vaccines are listed in the product information.
