Whether a runny nose can be vaccinated depends on the cause of the runny nose. If there is a cold, immunization is usually not recommended. If it is caused by chronic rhinitis and the patient does not have other symptoms such as fever, vaccination is possible. A runny nose is usually caused by bacteria or viruses attacking the respiratory tract, which is one of the manifestations of a cold, and vaccination is usually not recommended for patients with colds. Currently, vaccines are mainly classified into live attenuated vaccines and inactivated vaccines, which will stimulate the human immune system to produce specific antibodies to protect the body. When the body’s resistance is weak during a cold, vaccination may aggravate the condition and increase the risk of adverse reactions, so vaccination should be avoided. In addition, patients with chronic rhinitis can also have a runny nose, usually the symptoms of a runny nose alone, and last for a long time, these patients are not caused by infection, can be vaccinated. Before vaccination, it should be noted that if there is fever and other acute infections, the vaccination should be delayed; those who are allergic to vaccine components should not be vaccinated. After vaccination, alcohol consumption and strenuous exercise should be avoided, and wounds should be kept away from water for 24 hours.
