You can eat fish during rabies vaccination. Fish is a good food source to supplement protein, so fish can be eaten completely when vaccinated with rabies vaccine, which will not have any adverse effects or affect the efficacy of rabies vaccine. During the period of rabies vaccination, some people may have adverse reactions, such as mild fever or nausea due to loss of appetite. At this time, you should eat light food. If eating fish will not aggravate nausea, you can eat fish. If it causes slight nausea and indigestion, you can choose to eat less fish or not, but eating fish will not affect the effect of rabies vaccine. The fish eaten during rabies vaccination should be slightly light, and don't let go of spicy peppers. After the rabies vaccine is injected, you can't eat fish even during the rabies vaccine injection. Fish is a high-quality source for human body to ingest protein, and the fat content in fish is generally less, which can supplement human body's protein. Fish should be part of the diet. Don't eat too much fish, because eating too much may lead to indigestion. As long as this person is not allergic to the ingredients in the fish and eats a proper amount of fish, it will not cause gastrointestinal discomfort. Eating fish during or after rabies vaccination will not have a corresponding impact on rabies vaccine, that is, it will not affect the effect of rabies vaccine. So you can eat fish after rabies vaccine, but avoid putting spicy spices when cooking fish. Because during and after rabies vaccination, try not to eat too spicy food, don't drink alcohol, and don't drink strong tea.
