PORTLAND, Ore. (AP) --An Oregon health care worker has been hospitalized after having a severe allergic reaction to the Moderna COVID-19 vaccine.
The Oregon Health Authority says the employee at Wallowa Memorial Hospital experienced anaphylaxis after receiving a first dose of the vaccine this week.
The health authority said vaccines for COVID-19 can cause mild to moderate side effects in some people. This can include pain and swelling on the arm and sometimes fever, chills, tiredness and headache.
In rare cases, some people have experienced severe allergic reactions.
Health officials will continue to track adverse reactions. So far, 38,698 doses of the COVID-19 vaccines have been administered in Oregon since the week of Dec. 13.
