Background: Vaccination of the population is required to combat the COVID‐19 pandemic. Allergy testing could reduce anxiety towards COVID‐19 vaccination and thereby may increase vaccination rate, however, its effectiveness remains unclear. Methods: One hundred and thirty prospective real‐life patients in need of but not daring to get vaccinated asked for allergy workup for COVID‐19 vaccine hypersensitivity in 2021/2022. Characterization of patients, identification of anxieties, decrease of patient's anxiety levels, overall vaccination rate and adverse reactions after vaccination were assessed. Results: Tested patients were characterized by being female (91.5%) and having a high rate of previous allergies (e.g. to food 55.4%, drugs 54.6%, or previous vaccinations 50%) and dermatological disease (29.2%) but not always had medical contraindications for COVID‐19 vaccination. Sixty one patients (49.6%) were highly concerned (4‐6, Likert scale 0‐6) about vaccination and 47 (37.6%) expressed resolving thoughts about vaccinaion anaphylaxis (3‐6, Likert scale 0‐6). However only 35 patients (28.5%) were scared of getting COVID‐19 within 2 months (4–6, Likert scale 0–6) and only 11 (9%) patients had high expectations of getting COVID‐19 (4–6, Likert scale 0–6). Allergy testing significantly (p < 0.01 to p < 0.05 respectively) reduced the median anxiety of allergic symptoms following vaccination: dyspnoea (4.2–3.1), to faint (3.7–2.7), long‐term consequences (3.6–2.2), pruritus (3.4–2.6), skin rash (3.3–2.6) and death (3.2–2.6). After allergy testing, most patients (108/122, 88.5%) let themselves be vaccinated within 60 days. Revaccinated patients with previous symptoms experienced a reduction of symptoms (p < 0.05) upon revaccination. Conclusions: Patients not daring to get vaccinated have more anxiety towards vaccination than to acquire COVID‐19. For those, allergy testing excludes vaccine allergy, and is a tool to increase vaccination willingness and thereby helps to combat vaccination hesitancy. [ABSTRACT FROM AUTHOR]
