SINGAPORE (The Straits Times/ANN): There are some groups of people who should wait to receive a Covid-19 vaccine, including those with a history of severe allergic reactions, said a panel of experts on Thursday (Dec 17).
Serious allergies usually refer to people who, in response to a specific stimulus such as a bee sting or medication, experience swelling around the mouth, eyes or face, have difficulty breathing or experience a serious drop in blood pressure, said Associate Professor Lim Poh Lian, the director of the high-level isolation unit at the National Centre for Infectious Diseases.
