Vaccination against Covid-19: here’s how to report your side effects

Pain at the injection site, fatigue, flu-like state… Vaccination against Covid-19 can cause adverse effects. While most are mild, it is important to report to the health authorities those that seem more serious to you. Here’s how to do it.

When a drug is placed on the market, it is automatically subject to a pharmacovigilance investigation. We then monitor the various side effects that can occur after taking it, in the more or less long term, in order to better inform consumers.

The National Agency for the Safety of Medicines and Health Products (ANSM) has mobilized the regional pharmacovigilance centers (CRPV) to monitor the adverse effects of vaccines against Covid-19.

It’s up to them, via this dedicated portal, which you can contact in case of trouble. Since March 2017, the procedure has been simplified. You do not need the approval of your doctor or other healthcare professional. Explanations in four steps.

Applicant Status

Start by setting your status first. The portal for reporting adverse health events, deployed by the Ministry of Health, offers three.

If you are unsure of yourself, click on “You are an individual”.

Choice of the drug concerned

Several types of drugs and medical procedures are then offered: vaccines, including against Covid-19, food supplements, bone marrow transplant, IVF, radiotherapy, etc.

Once you have made your choice, you can move on to the next steps and continue with your declaration.


Description of side effects

This is the key moment in your statement. Enter all the information requested, your medical history, and the vaccine concerned by the declaration.

For Pfizer, this is the “COMIRNATY BioNTech-Pfizer” 10 or 30 micrograms. For Moderna, “SPIKEVAX – COVID-19 Vaccines Moderna”. Specify the mode of injection (most of the time, intramuscularly).


Regarding the description of side effects observed, it is important to be brief, but precise. You can report several different side effects at the same time.

Summary and sending of the report

Check the accuracy of the information provided. They will be studied by the CRPV according to your place of residence.

They may need to contact you again. If necessary, your report will be processed anyway and can improve the management of these adverse effects.

In case of doubts or really serious effects, you should contact your doctor or 15.
