What about the AstraZeneca and Janssen vaccines? A slight increase in cardiovascular risk has been observed. More specifically, this refers to an increased risk of myocardial infarction and pulmonary embolism in adults within two weeks of receiving these vaccines. However, the study authors point out that “COVID-19 itself is strongly associated with a risk of cardiovascular complications . “
What are the reactions associated with the Moderna vaccine?
Since November 2021, the Moderna vaccine (or Spikevax) has been reserved for French citizens over 30 years of age. 22,332,200 Moderna vaccine injections have been administered since its inclusion in the vaccination campaign.

During the period from December 31, 2021 to January 13, 2022, the ANSM identified new events to monitor, namely cases of thyroiditis, musculoskeletal disorders, systemic vasculitis with anti-neutrophil cytoplasmic antibodies (ANCA) and cerebral venous thrombosis.
She notes that confirmed adverse events include painful, erythematous, and pruritic local reactions at the injection site, vascular disorders such as hypertension, myocarditis, and pericarditis, as well as erythema multiforme. She also points out that potential adverse events or those already under surveillance include cardiac arrhythmias, shingles, rheumatoid arthritis, hearing problems, and menstrual disorders.
