It is possible to eat leeks during rabies vaccination. Although it is forbidden to drink alcohol or strong tea or coffee during the rabies vaccination, the mechanism does not absolutely affect the effect of the rabies vaccine, only that drinking more alcohol may reduce the effect of the rabies vaccine, and drinking other than alcohol generally does not have too much effect on the effect of the vaccine. It is only that some people who have received the rabies vaccine will have adverse reactions, such as fever or a general feeling of exertion, which requires attention to rest, and drinking strong tea and coffee will lead to poor sleep and will affect rest, so these aspects should be avoided. Eating leeks will not affect rest or the effectiveness of the rabies vaccine, so you can eat leeks. However, people who usually do not have a good gastrointestinal tract should not eat leeks if they will stimulate their stomach and cause stomach pain or even lead to the appearance of stomach ulcers. People who usually have peptic ulcers may also eat leeks, which may aggravate their symptoms, and try not to eat leeks for this reason, but it has no effect on the rabies vaccine.
