3 people experienced severe allergic reaction to COVID-19 vaccine (Singapore)
SINGAPORE: Three cases of anaphylaxis - or rapid onset of severe allergic reactions - were reported out of the more than 113,000 people who have received the COVID-19 vaccine to date, the Ministry of Health (MOH) said on Thursday (Jan 28).
“The individuals, in their 20s and 30s, developed multiple symptoms such as rash, breathlessness, lip swelling, throat tightness and giddiness,” said MOH.
“All three individuals had a history of allergies, including allergic rhinitis and food allergy such as to shellfish, but none had a history of anaphylaxis which would have precluded them from receiving the vaccine.”
It added: “Anaphylaxis can be controlled when detected and treated in a timely manner. As all vaccinated persons in Singapore are closely monitored, the symptoms in these three individuals were promptly detected and treated."
All three have recovered from the episode and were discharged from the hospital after a day’s observation or treatment.
