This is a prospective study enrolling a total of approximately 120 subjects, 18-55 years old.', 'detailedDescription': 'Background: Allergic rhinitis (AR) is a disorder caused by hypersensitivity of the immune system to harmless allergens in the environment, which represents a global public health problem affecting up to 20-50% of the population. Allergen immunotherapy (AIT) is the only effective treatment that not only has disease-modifying property but also confers long-term clinical benefit after cessation of treatment for AR patients. Vaccination is one of the most powerful interventions for reducing disability and death caused by infectious disease. Immunization with the inactivated SARS-CoV-2 Vaccine remains the most effective strategy to combat COVID-19 infections. Nevertheless, the influences of allergic rhinitis and allergen immunotherapy on SARS-CoV-2 vaccination are still unknown.\n\nObjectives: To investigate if AR and AIT will influence the humoral response to SARS-CoV-2 vaccination in adults.\n\nDesign and trial size: This is a prospective study. A total of approximately 120 subjects, 18-55 years old, including 40 healthy subjects, 40 patients with AR without AIT, and 40 patients with AR with AIT for more than 1 year, will be enrolled in this study.\n\nIntervention and duration: All of the study participants will be vaccinated with an 2 doses inactivated vaccine against SARS-CoV-2 (COVILO). Peripheral blood samples will be collected at baseline (prior to vaccinate), 7 and 30 after first vaccine, and, 7 and 30 after second vaccine. One-month additional data analysis leads to the trial duration of 3 months.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': '18-55 years; healthy subjects, patients with AR without AIT, or patients with AR with AIT for more than 1 year', 'eligibilityCriteria': 'Inclusion Criteria:\n\n18-55 years; healthy subjects, patients with AR without AIT, or patients with AR with AIT for more than 1 year\n\nExclusion Criteria:\n\n1. who infected with COVID-19 previously\n2.
