INNational Agency for the Safety of Medicines Therefore, on July 16, 2021, a report was drawn up listing all the side effects of the vaccines reported by the French. Pfizer, AstraZeneca, Moderna and Janssen : All vaccines approved in France have been analyzed.

  • Rheumatoid arthritis (RA): 3 severe cases, including one positive re-injection.
  • Glomerular nephropathies: 3 cases of glomerular nephropathies, including 2 positive re-dosing after dose 2 and one case after dose 2. These cases occurred in patients aged 20 to 80 years, all within a short period of time (<2 days).
  • Skin bleeding of the mucous membranes (menstrual irregularities): 15 severe cases. In the absence of further assessment of reported cases, it is impossible to foresee the role of the vaccine in their occurrence.

  • Amnesic attack (transient amnesia)
  • Hearing problems (deafness, hearing loss, and tinnitus)

AstraZeneca

Observed side effects:

  • Mucocutaneous bleeding (mainly bruising and nosebleeds)
  • Shingles and herpetic reactivation
  • Increased blood pressure
  • Shortness of breath and asthma associated with flu-like syndromes

  • Facial nerve palsy
  • Central demyelinating pathology
  • Erythema nodosum
  • Deafness and hearing loss
  • Ischemic colitis
  • Vasculitis
  • Myocarditis / pericarditis
  • Influenza-like syndromes: These are still the most commonly reported and new data collected confirms the results of previous weeks.
  • Thromboembolic Disorders: In order to harmonize French monitoring of thromboembolic disorders analyzed at a European level, it was decided to focus monitoring on the following events:
    • cerebral thrombosis
    • internal thrombosis
    • multipoint thrombosis
    • any thrombosis associated with thrombocytopenia
    • isolated internal combustion engines.

Faced with the risk of thrombosis, ANSM ” Recommends to anyone with persistent side effects for more than 3 days, such as dizziness, headache, visual disturbances, nausea / vomiting, shortness of breath, sharp pain in the chest, abdomen or limbs, or who have bruises on the skin (petechiae) outside the site vaccination, seek medical attention immediately… “

    • Venous and / or arterial thrombosis of unusual localization (localization, clinical context, possibly multiple sites, sometimes sequentially), in particular cerebral vein thrombosis and internal vein thrombosis.
  • Capillary Leak Syndrome: The effect has been reported worldwide, no cases have been reported in France to date

Generally, no serious side effects absolutely related to Covid-19 vaccines have not been found in France, among pregnant or lactating women… Very good news for young parents who may be worried about the consequences of this epidemic for their child or themselves.
