Avoid vaccination with CAPV during a cold or flu and wait until the disease has fully recovered. If the vaccine is given during a cold, it may increase the number of adverse reactions and may even cause the vaccine to be ineffective. Most colds are caused by viral infections. Since the body’s immune system is relatively weak during a cold, vaccination with CKPV during a cold can aggravate the condition and symptoms of the cold. Colds are usually characterized by a runny nose, sneezing, coughing and even fever, and people with fever are contraindications to vaccination with the CKP vaccine. Secondly, some people may experience fever and localized pain after vaccination with the CKP vaccine, which may aggravate and overlap the occurrence of the adverse reactions. Injection of the new crown pneumonia vaccine needs to be evaluated by a professional physician after injection, patients in the acute phase of the disease state, prohibit injection of the vaccine.
