Most people can eat popsicles after the New Crown vaccine, but for people with poor gastrointestinal function and those who experience headache, fever, nausea, diarrhea and other uncomfortable symptoms after New Crown vaccination, eating popsicles after New Crown vaccination is not recommended. Eating popsicles is not a contraindication after New Crown vaccination. Eating a little popsicle after New Crown vaccination will not affect the activity and effect of the vaccine, but it is not recommended to eat popsicles or other cold drinks immediately or in large quantities after vaccination. Eating popsicles at this time may aggravate the discomfort of the digestive tract and cause abdominal pain and diarrhea in people with poor gastrointestinal function. Some people may experience headache, fever, nausea, diarrhea and other gastrointestinal adverse reactions after receiving the vaccine. Eating popsicles at this time may aggravate the discomfort on the one hand, and may cover up other adverse reactions after receiving the vaccine and delay treatment on the other. For a short period of time after vaccination, it is recommended to eat a light diet, eat more fresh fruits and vegetables to ensure balanced nutrition, do not drink alcohol or eat stimulating foods such as too spicy and cold, ensure sufficient rest, avoid staying up late and straining, and maintain good living habits.
