If you are not allergic to beef or protein-based foods, you can eat beef in moderation after the new vaccine. Beef has more protein, minerals and other nutrients, which are beneficial for improving resistance. When consuming beef, attention should be paid to the cooking method of beef, with as little oil and salt as possible, avoiding deep-frying, stir-frying, salt baking and other cooking methods, as well as the need to choose fresh beef to prevent food spoilage and burden on the organism. In addition, care needs to be taken to avoid consuming too much beef to avoid burdening the gastrointestinal tract and causing abdominal pain, diarrhea, nausea, vomiting, belching and other gastrointestinal symptoms, which may induce or aggravate adverse reactions to vaccination and indirectly affect the performance of the vaccine in the body. In addition, within one week of vaccination, avoid eating spicy and allergy-prone foods, such as seafood, and eat meat, eggs, milk, soy products and fresh vegetables and fruits to replenish the nutrients needed by the body, which will help the vaccine to function as well as reduce the adverse reactions of the body.
