If you have a cough after vaccination, you should first find out the cause of the cough, and carry out different treatments according to different illnesses. You should not treat blindly without determining the specific cause of the illness, so as not to aggravate the condition. If the cough is not particularly serious and the body temperature is below 37.5℃, there is no need to be particularly nervous, which may be due to the body’s rejection reaction after vaccination. If the cough is particularly severe, you need to go to the hospital immediately for treatment. If the cough is caused by a bacterial infection, it can be treated with antibiotics. If the cough is due to a viral infection, it can be treated with antiviral medication.
