“There is no need to prove that the medicine caused the adverse reaction, just the suspicion is good enough.”
Dr. June Raine, Chief Executive Officer of the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA), quoted in The Guardian
What is an adverse reaction or event, and why should I report it?
An adverse reaction or event is any negative change in your health or new illness that happens during or after treatment with a medicine.
Adverse reactions include physical events such as headache or an allergic reaction, a psychological symptom such as brain fog, a change in clinical measurements, such as reduced blood platelet levels, or a worsening of a pre-existing medical condition, such as diabetes. These reactions can happen at any time – shortly after using a medicine or even many years later.
Individuals and their health care provider must report adverse events so that regulatory authorities can monitor a medicine’s safety and identify any problems that have not been discovered yet. It also helps the authorities to change advice for healthcare workers and the public.
How do I report a Covid-19 vaccine adverse event or side effect?

Covid-19 vaccines are a new type of therapy and their safety is unknown; therefore it is especially important to report serious side effects. Depending on where you are in the world, there are various databases set up to record adverse drug reactions:
