Diarrhea is also known as diarrhea. During diarrhea, temporary postponement of the New Crown vaccination may be considered. Simple manifestations of diarrhea are not strictly contraindicated for New Crown vaccination, but vaccination at this time may induce or add to adverse reactions to New Crown vaccination, such as nausea and dizziness, or poor immune function that may affect the effectiveness of New Crown vaccination. You can consult with the doctor at the New Crown vaccination unit to assess the severity of diarrhea before deciding whether or not to vaccinate. Diarrhea can usually be recovered in a short period of time, so you can pay attention to personal protection during diarrhea, and postponing vaccination for a short period of time will generally not cause serious consequences; and when diarrhea is more serious, it usually requires medication, especially diarrhea caused by infection, which is often accompanied by fever and other symptoms and requires oral antibiotics and other medication. In addition, vaccination with the New Crown vaccine may cause local or systemic reactions of varying degrees while inducing an immune response in the body, and common adverse reactions include gastrointestinal symptoms such as bloating and diarrhea, which may aggravate diarrhea symptoms and affect the effect of the New Crown vaccine if the body’s immune status is poor. If you have diarrhea, you need to replenish water and electrolytes in time, and you need to go to hospital for treatment in time to avoid serious dehydration and actively look for the cause of the disease.
