At present, allergic rhinitis and asthma show a high incidence. According to the figures published by the World Health Organization, there are about 500 million rhinitis patients among more than 6 billion people in the world, and there are nearly 50 million allergic rhinitis patients in China, and its incidence is increasing year by year, especially in children. It seriously affects the growth, development and learning of children. At present, many hospitals are using nasal spray hormone. The national rhinology expert group in the latest allergic rhinitis diagnosis and treatment guidelines clearly pointed out that anti-allergic drugs or hormones can only relieve the disease, sometimes using intranasal, intramuscular injection method, which is not beneficial to the treatment of the disease, its side effects are very large, causing harm to the growth and development of children. Immunotherapy (i.e., desensitization) is the treatment that the group of experts has promoted, i.e., the vaccine treatment method, which, after 2-3 years of regular treatment, can significantly improve the patient’s allergic constitution, thus achieving the goal of less or no allergic rhinitis. For patients with simple allergic rhinitis, immunotherapy can also prevent the occurrence of asthma.
