Drinking carbonated beverages with rabies vaccination is allowed and usually does not have any effect on the production of rabies virus antibodies. Rabies vaccine is a biological agent used to prevent the rabies virus from infecting the body. After the body is vaccinated with rabies vaccine, it will stimulate the humoral and cellular immunity, which will lead to the production of antibodies against the rabies virus in the body. The body may have some adverse reactions such as gastrointestinal discomfort and mild fever after rabies vaccination. Drinking cola after rabies vaccination may aggravate the burden on the gastrointestinal tract and therefore may slightly aggravate the adverse reactions after vaccination, but there is no prohibition against drinking cola after rabies vaccination. Drinking cola will not affect the efficacy of rabies vaccine, so as long as there is no gastrointestinal discomfort, you can drink cola in moderation.
