Whether or not the Neocon vaccine can be given for mild diarrhea depends on the individual patient’s situation. If there is only mild diarrhea, no other abnormal symptoms, and no allergy to the vaccine, the vaccine is generally acceptable. However, if mild diarrhea is accompanied by abdominal pain, nausea, vomiting, fever, etc., then the vaccine is not recommended. When only mild diarrhea is manifested, it may be related to poor diet and no inflammatory infection has occurred in the organism, and the vaccine can be given at this time without usually affecting the vaccination effect or aggravating the diarrhea. However, for insurance purposes, it is still advisable to report your personal situation to the medical staff in a timely manner, and if it is possible to adjust the vaccination schedule, it is still recommended to wait until the diarrhea symptoms have completely subsided before receiving the New Crown vaccine. If there is mild diarrhea, accompanied by abdominal pain, nausea, vomiting or even fever, it is mostly related to viral, bacterial and other pathogenic infections. At this time, the organism may be in a period of acute inflammatory infection, and the Technical Guideline for Vaccination of New Coronavirus (First Edition) issued by the Health Care Commission clearly stipulates that such cases cannot be vaccinated with the New Coronavirus vaccine in order to avoid reducing the immune response effect of the vaccine and may also aggravate gastrointestinal discomfort and adverse reactions to vaccination.
