Have a history of severe allergies to any component of the research vaccine, including aluminum preparations, such as: anaphylactic shock, allergic laryngeal edema, allergic purpura, thrombocytopenic purpura, local allergic necrosis (Arthus reaction); or any previous History of serious side effects of vaccines or drugs, such as allergies, urticaria, skin eczema, dyspnea, angioedema etc. 7.

For corticosteroids, this will mean prednisone 0.5 mg/kg/day, or equivalent. Inhaled and topical steroids are allowed; 11. Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination 12.
