Babies with bronchitis are not allowed to get vaccinations. When a baby has bronchitis, he or she will have fever, cough, phlegm, loss of appetite, and even nausea, vomiting, and diarrhea. At this time, the body’s immunity is relatively low. If vaccination is given, as the vaccination will stimulate the immune system to produce an immune response, forcing the immune system to produce specific antibodies, fever will appear, aggravating the original fever of the baby’s bronchitis, and high fever may occur, aggravating the condition and detrimental to disease recovery. The process of treating bronchitis in babies with medication affects the formation of vaccine antibodies and the effectiveness of vaccination. It is recommended that parents actively treat bronchitis first and then give the vaccination to the baby after the disease has been cured.
