Severe allergic reactions to COVID-19 vaccines are exceedingly rare according to health authorities in the US, where more than 11 million people have now received at least one dose of a COVID-19 vaccine.
At that point, 1.9 million people had been vaccinated, putting the rate of severe allergic reactions at 11.1 cases per 1 million doses of vaccine used.
Since the report was finalised, at least eight more cases of vaccine-related anaphylaxis have been confirmed in the US, as millions more Americans receive their first COVID-19 jab.
