Among the 9,396 reports, 2,845 were recorded in the European pharmacovigilance database EudraVigilance. The vast majority of reported side effects were fever, muscle pain, malaise and injection site reactions. “These are known side effects and are described in the package leaflet (of the vaccine). These reactions are normal and indicate activation of the immune system. They usually go away after about two days“, emphasizes the FAMHP.
Increase confidence in vaccines
“Adverse reactions were more frequently reported after administration of the second dose with Pfizer / BioNTech and Moderna vaccines, whereas with AstraZeneca vaccine they were more frequently reported with the first dose“, adds the federal agency.
A total of 1,683 other reports are listed as serious since they resulted in temporary incapacity for work or inability to leave home due to fever, muscle pain, malaise and injection site reactions. The figures were counted until March 29, when 1,236,430 people had received at least one dose of Covid-19 vaccine in Belgium. The FAMHP also stresses that this information concerns suspected adverse effects, that is to say medical effects observed after inoculation of a vaccine, but which are not necessarily linked or caused by the vaccine. The FAMHP publishes a weekly overview of the adverse reactions reported following the administration of a Covid-19 vaccine in Belgium, its objective being to increase confidence in vaccines by being transparent.
