A health care worker in Oregon was hospitalized after having a severe allergic reaction to the Moderna COVID-19 vaccine, according to the Oregon Health Authority.
The worker, an employee at Wallowa Memorial Hospital, experienced anaphylaxis after receiving a first dose of the vaccine this week, officials said.
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.
“The Centers for Disease Control and Prevention has reported that in rare cases, some people have experienced severe allergic reactions after getting a COVID-19 vaccine,” health officials said in a press release. “An allergic reaction is considered severe when a person needs to be treated with epinephrine or EpiPen, or if they must go to the hospital.”
Health officials will continue to track adverse reactions to the COVID-19 vaccines.
So far, 38,698 doses of the COVID-19 vaccines — 26,639 of Pfizer-BioNTech and 12,054 of Moderna — have been administered in Oregon since the week of Dec. 13, officials said.
