Some people fear a lack of perspective and research on vaccines against Covid-19. So months after the beginning of their use, what about the side effects associated with the four vaccines authorized in France nationwide?

Over 33,000 cases of adverse reactions deemed not to be serious

This Friday, July 16, the National Agency for the Safety of Medicines and Health Products (ANSM) provided its update on the side effects of vaccines against Covid-19.

Since the start of the vaccination, ANSM has put in place a pharmacovigilance system. Thus, with the French network of Regional Pharmacovigilance Centers (CRPV), the Agency analyzes the statements made by health professionals, vaccinated people and their families. The aim is to prevent unwanted effects from vaccines in France.

In total, of the 45,779,000 injections carried out against Covid-19 until July 8, 2021, 33,296 cases of adverse reactions have been identified. However, the ANSM believes that “The majority of side effects are expected and not serious. “So there is no picture: the risk-benefit balance is largely in the direction of vaccination.

What are the side effects of vaccines?

The Pfizer vaccine

  • 45,799,000 French people  received it.
  • 64 cases of myocarditis(0.0001%)
  • 111 cases of pericarditis(0.0002%)

The Moderna vaccine

  • 5,566,000 doses have been injected.
  • 7 cases of myocarditis (0.0001%)
  • 13 of pericarditis (0.0002%).
  • Three severe cases of rheumatoid arthritis(0.00005%)
  • three cases of glomerular nephropathy(0.00005%) 


  • 7,210,000 injections were performed
  • 53 cases of thromboembolic disorders(0.0007%) have been identified, including 13 fatal.


  • 609,000 injections have been made
  • In total, 243 cases of side effects were detected, including 4 Guillain-Barré syndromes.

In view of this large study, we can assume confidently that vaccines against Covid-19, especially using the ARN messenger, are highly effective for an extremely low risk.
