Table 2. Allergic risk assessment for COVID-19 vaccination. Modified from Worm et al., MMW 2021 [19].

Vaccination unproblematic from the current allergological point of view	Vaccination with increased risk awareness* or preceding allergic workup	No vaccination according to summary of product characteristics and from an allergological point of view
- Allergic asthma - Allergic rhinoconjunctivits - Atopc eczema - Food allergy - Insect venom allergy - Allergic contact eczema - Urticaria - History of drug eruption - Delayed local reactions to vaccinations	Anaphylaxis treated by a physician - during a vaccination or medical procedure like coloscopy, surgical intervention under general anesthesia - after (repeated) drug intake - of unclear pathogenesis	History of severe allergic reactions to one or several of the vaccine ingredients

*Whether mastocytosis per se is associated with an increased risk of vaccination has not been clearly established to date.
