Try not to get vaccinated when you have a cold, but postpone the vaccination until your cold has cleared up. Influenza vaccine is a vaccine used to prevent the influenza virus from infecting the body, and after vaccination, it can induce the body’s immune system to produce humoral and cellular immune responses. When receiving the influenza vaccine, it is important to be aware of any contraindications to the vaccination. Contraindications to influenza vaccination include allergy to the vaccine and any of its active ingredients, acute or chronic disease exacerbation, and fever. Colds are contraindications to influenza vaccination because they are part of an exacerbation. In this case, it is recommended that the flu vaccine be given after the cold has cleared up. After receiving the flu vaccine, you should pay attention to rest and eat a light diet to avoid discomfort.
