A healthcare worker in Wallowa County, Oregon, has had a severe allergic reaction to the Moderna vaccine that required hospitalization.
According to the Oregon Health Authority, the individual experienced anaphylaxis after receiving their first dose of the Moderna vaccine in the week of December 25. They are currently recovering at a hospital.
The Centers for Disease Control and Prevention have reported that this is not the only case of a person experiencing severe allergic reactions after getting a COVID-19 vaccine.
COVID-19 vaccines can cause mild to moderate side effects in some people, including pain and swelling on the arm, and sometimes fever, chills, tiredness, and headache. These are normal signs that the body is building an immune response against the virus, and while they may affect ability to do daily activities, they should subside in a few days.
