Adverse reaction reports summarise all reports of suspected adverse reactions that we have assessed. Events following vaccination are reported on the basis of suspicions, which means that there is not necessarily any causal relationship. The challenge is to distinguish symptoms and medical conditions which occur randomly from those which could be linked to vaccination. All reports are included in the report, regardless of whether or not an event is believed to be linked to vaccination.
Reports of serious events are given priority and assessed first. The figures therefore do not give a true picture of the distribution between serious and non-serious events.

Reports of suspected adverse reactions in the 12-17 age group
The monitoring of adverse reactions amongst children and adolescents is given a high priority. We are closely monitoring the situation and are particularly alert to reports of serious events following vaccination. Almost 100,000 doses have so far been administered to children and adolescents aged between 12 and 17. During the period December 2020 to 7 September 2021, we received and assessed 15 adverse reaction reports concerning this age group. Six of these are classified as serious.
Adolescents normally experience the same common and transient adverse reactions as adults following vaccination. Amongst the more rarely known adverse reactions are inflammation of the heart muscle (myocarditis) and inflammation of the heart lining (pericarditis). No reports of these adverse reactions have so far been received concerning this age group. Look out for symptoms such as chest pain, wheezing or rapid or irregular heart rate in vaccinated people. Fever and cough may also occur.
Contact a health professional, such as a public health nurse or a doctor, for an assessment and advice if a child or adolescent is experiencing troublesome adverse reactions. Health professionals are obliged to report serious, new and unexpected reactions which they suspect may be caused by a vaccine.
Report adverse reactions on behalf of children
Children under 16: Parents and guardians can report adverse reactions on behalf of their child.
Children over 16: Young people over the age of 16 can report adverse reactions themselves, but they will need an electronic ID, such as Bank-ID. Parents can report adverse reactions if a power of attorney has been set up. Power of attorney can be set up digitally via helsenorge.no.

Reports of menstrual disorders
We are still receiving many reports of menstrual disorders and unexpected vaginal bleeding following vaccination.
“Little is known about this issue and we do not yet understand the mechanism involved, so we are unable to rule out a link. Factors such as stress, surgery, illness and weight loss are known to affect the menstrual cycle. It is therefore not inconceivable that an immune response following vaccination could disrupt the menstrual cycle,” says Senior Consultant Sigurd Hortemo.
How to report adverse reactions

Please remember to include the following information when reporting adverse reactions:
- name of the vaccine and date of vaccination
- detailed description of the sequence of events
- when the adverse reaction first started
- whether the reaction is persistent or has passed
- other current medical conditions and medication
- if/when a COVID-19 test has been taken, and the result
- whether the reaction occurred after the first or second dose
- whether a different type of vaccine was given as the second dose
- the results of any blood tests or other medical investigations
- whether a doctor has been contacted (for those submitting a “patient report” via helsenorge.no)
It is particularly important to report reactions where any of the following are suspected:
- new adverse reactions not referred to in the patient information leaflet
- unexpected adverse reactions
- serious adverse reactions
- vaccine failure (severe COVID-19 following full vaccination)
