It is normal to have certain reactions after the vaccination. Most 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. There may be redness, swelling or pain around the injection site. Fatigue, fever, headache and aching limbs are also not uncommon in the first three days after vaccination. These symptoms are more frequent and severe following the second dose and among younger persons compared to older persons (i.e., >55 or ≥65 years). If symptoms start 3 days after vaccination or symptoms last longer than 2 days, Covid-19 testing is recommended.
After receiving your vaccine, please register for V-Safe, a smartphone-based tool that provides personalized check-ins so you can quickly tell the Centers for Disease Control and Prevention (CDC) if you have any side effects or report and side effects through the CDC Vaccine Adverse Reporting System (VAERS).
