Before vaccination, providers should counsel mRNA COVID-19 vaccine recipients about expected local (e.g., pain, swelling, erythema at the injection site, localized axillary lymphadenopathy on the same side as the vaccinated arm) and systemic (e.g., fever, fatigue, headache, chills, myalgia, arthralgia) post-vaccination symptoms. Depending on vaccine product (Pfizer vs. Moderna), age group, and vaccine dose, approximately 80–89% of vaccinated persons experience at least one local symptom and 55–83% experience at least one systemic symptom following vaccination.
Most systemic post-vaccination symptoms are mild to moderate in severity, occur within the first three days of vaccination, and resolve within 1–3 days of onset. These symptoms are more frequent and severe following the second dose and among younger persons compared with older persons (i.e., ages >55 or ≥65 years [for Pfizer-BioNTech or Moderna vaccines, respectively]). Unless persons experience a contraindication to vaccination (see below), they should be encouraged to complete the series even if they experience local or systemic symptoms following the first dose to optimize protection against COVID-19.
In clinical trials, hypersensitivity-related adverse events were observed in 0.63% of participants who received the Pfizer-BioNTech COVID-19 vaccine and 1.5% of participants who received the Moderna COVID-19 vaccine, compared with 0.51% and 1.1%, respectively, in the placebo groups.

Moderna COVID-19 Vaccine, codenamed
mRNA-1273, is a COVID-19 vaccine developed by the United States National Institute of Allergy and Infectious Diseases, the Biomedical Advanced Research and Development Authority, and Moderna. It is administered by two 0.5 mL doses given by intramuscular injection given four weeks apart.
BioNTech CEO Ugur Sahin, M.D., Ph.D., led research showing an
mRNA vaccine based on technology similar to that used for the Pfizer-partnered COVID-19 vaccine BNT162b2 worked in mouse models
