The period of rhinitis attack can be divided into acute rhinitis attack period, chronic rhinitis acute attack period and chronic rhinitis non-acute attack period. The first two cases are not recommended for vaccination with the new crown vaccine, while the latter can be vaccinated. It is recommended that the attack period be treated in a timely manner and vaccinated after stabilizing the disease: I. Acute and chronic rhinitis attack period: 1. Aggravation: During the rhinitis attack period, it can be mostly manifested as dryness, burning sensation and itching in the nasal cavity. The nasal congestion, frequent sneezing, runny nose, clear watery nose and even rhinorrhea may occur. In case of severe symptoms, fever and malaise may occur. Since the body has an inflammatory reaction and the immune function is in a state of decline, vaccination at this time may aggravate the condition. Since the vaccine is a foreign substance to the body, the immune system automatically responds to it, which may lead to the aggravation of the symptoms of rhinitis, or the appearance of concurrent respiratory symptoms, such as coughing and coughing, making the treatment and recovery more difficult. 2. It can also aggravate the adverse reactions of the vaccine, with local redness, swelling, pain and hard nodules at the vaccination site, and in serious cases, systemic symptoms such as malaise, fever and headache, as well as allergic reaction to the new crown vaccine. II. Non-acute attack period of chronic rhinitis: The non-acute attack period of chronic rhinitis is characterized by mild nasal congestion and loss of smell.
