An Israeli study of 429 'highly allergic' people who received the Pfizer COVID-19 vaccine found 98 per cent of them (420 people) had no allergic reaction to the jab, 1 per cent (six people) had a mild allergic reaction, and 0.7 per cent (three people) had anaphylactic reactions. The rate of allergic reactions to the Pfizer vaccine is higher among patients with allergies than among those without, the researchers say. They used artificial intelligence to select 'highly allergic' people based on questionnaire responses, and say the same method could be used to select vaccination candidates who are most at risk of an allergic reaction, and who should therefore be supervised while receiving the jab.
