It is best not to eat barbecue for a week after vaccination. Barbecue is generally a spicy and stimulating food, which may affect the effect of vaccine absorption by the body and is not conducive to maximizing the effect of the vaccine in the body. Also, some patients may have adverse reactions, such as fever and rash, within a week after vaccination. Barbecue may further stimulate the organism and aggravate gastrointestinal reactions, such as acute enteritis and gastritis, nausea, vomiting, diarrhea, etc., due to the addition of more spicy and irritating excipients or the lack of hygiene requirements, which may aggravate the discomfort after vaccination and endanger the health. In addition there is also a possibility that it may be mistaken for an adverse reaction to the vaccine, resulting in a false positive result. You can stay in the hospital for a period of observation after the vaccination to make sure there are no adverse reactions before leaving. You need to pay attention to eat less oil, less salt, easy to digest food and drink more water. If you want to eat barbecue after vaccination, you can choose a regular restaurant that meets hygiene requirements and has a license to operate, and avoid adding spicy and irritating auxiliary ingredients such as chili powder. In addition, choose fresh meat as much as possible and make sure it is well cooked before eating, eat less fatty meat and try not to eat burnt meat.
