Regarding the product of Modern, diarrhea and local delayed-onset reactions have been incorporated into the data sheet and package leaflet as possible adverse reactions. Immune thrombocytopenia cases continue to be studied, pending analysis of additional data to determine if there is any causal relationship with the administration of the vaccine.

Most of these cases were not serious, resolved within a few days, and mostly affected young men (under 30 years of age), with symptoms beginning a few days after the vaccine was administered (almost all after receiving the second dose of the Pfizer vaccine).

“In the countries of the European Economic Area (EEA), notifications of myocarditis and / or pericarditis have also been received for the different vaccines that are being administered.
