It is possible to eat ice-cream after rabies vaccination, and eating ice-cream usually does not affect the effect of rabies vaccination. However, attention should be paid to moderation to avoid gastrointestinal discomfort caused by excessive consumption. Rabies vaccine is a preparation used to prevent the body from being infected with the rabies virus. After receiving rabies vaccine, the body’s immune system will react and generate antibodies, but at the same time, other organs and systems of the body may also have some adverse reactions, such as mild fever, joint and muscle pain, dizziness and headache, as well as gastrointestinal tract dysfunction, and so on. As gastrointestinal disorders may occur after rabies vaccination, ice-cream can only be consumed in small quantities after vaccination to avoid gastrointestinal discomfort due to coldness in the gastrointestinal tract, which is difficult to differentiate from the adverse reactions caused by vaccination. After vaccination, pay attention to a light diet and avoid spicy, stimulating and seafood and other foods that are easy to cause allergies.
