You can’t get vaccinated if you are already infected with influenza. During the period of influenza, the body’s resistance is weaker, and the vaccine may aggravate the symptoms of influenza such as cough, sore throat, and runny nose, which is not conducive to the recovery of the patient; secondly, it is difficult to detect the adverse effects of the vaccine during the period of influenza, and the vaccine’s adverse effects and the similarity of the symptoms of influenza are easy to delay the condition, resulting in serious adverse effects. In addition, it is often necessary to take medication during the influenza period, and the medication will affect the production of immune antibodies in the body, thus affecting the effectiveness of the vaccine. Therefore, vaccination is not recommended for patients with influenza. Patients suffering from influenza should go to the hospital in a timely manner, under the guidance of the doctor to carry out regular treatment in a timely manner, and then receive the vaccine after their condition has recovered.
