evidence: According to data by the CDC, Moderna’s COVID-19 vaccine induces rare anaphylactic reactions in a small number of people, similar to that found in recipients of the Pfizer/BioNTech vaccine. Reported by STAT, the CDC estimated a prevalence of 2.1 cases of anaphylaxis per million doses of the Moderna vaccine and 6.2 cases per million doses of the Pfizer vaccine. [...] Moderna will test 2 COVID-19 booster shots designed to be more effective against emerging variants, with one targeting the South African variant and the other to fight new mutations. The move comes amid reports that its approved vaccine was less potent against the variant identified in South Africa. [...] A small number of people who received Moderna’s COVID-19 vaccine experienced delayed, large, localized skin irritations around the injection site. Although the symptoms were reported to have cleared up in a median of 8 days, physicians should be made aware about the potential adverse effect in order to navigate proper treatment and guidance, according to researchers.
