[Asia Economy Reporter Hyunwoo Lee] The U.S. Centers for Disease Control and Prevention (CDC) announced that patients who experience severe allergic reactions after receiving the novel coronavirus disease (COVID-19) vaccine are prohibited from receiving the second dose. In the United States, out of approximately 270,000 people vaccinated so far, six have reported adverse reactions.

According to foreign media including CNN on the 19th (local time), the CDC stated in a press release, "We have received reports of severe allergic reactions in some vaccine recipients," and "Those who experienced such reactions after the first dose should not receive the second dose." The CDC defines 'severe allergy' as a physical reaction requiring treatment with the allergy medication epinephrine or hospitalization.

The CDC recommends consulting with a primary care physician before receiving the COVID-19 vaccine if one has previously experienced severe allergic reactions to other vaccines. However, it added that individuals with a history of severe allergies unrelated to vaccination may still receive the COVID-19 vaccine. According to the CDC, since the start of Pfizer vaccine administration in the U.S. on the 14th, a total of 272,001 people have been vaccinated, with six reporting adverse reactions.

Prior to the U.S., the United Kingdom, which began administering the Pfizer vaccine on the 8th, reported two cases of severe allergic reactions, and the UK health authorities have prohibited the second dose for individuals who experience such reactions. Pfizer's vaccine requires a second dose three weeks after the first. The day before, the U.S. Food and Drug Administration (FDA) announced that it is jointly investigating the causes of severe allergic reactions reported after Pfizer vaccination with the CDC and UK health authorities. Peter Marks, director of the FDA's Center for Biologics Evaluation and Research (CBER), explained, "The cause of the allergic reactions is not certain," adding, "A chemical component called polyethylene glycol included in the Pfizer and Moderna COVID-19 vaccines may be the cause."
