What is the harm of a mild cold vaccine?

A mild cold vaccine will reduce the effect of the vaccine. During the cold period, the body's resistance is relatively poor. Vaccination may cause adverse reactions of the vaccine to worsen. It is recommended that the vaccine should be injected after the cold recovers. Patients with cold should drink more water and rest more. When the symptoms are more serious, they should also be treated with paracetamol tablets according to the doctor's advice.
