After vaccination, it is not recommended to eat hot pot within 1 week. Because hot pot is usually greasy, most of the ingredients or soup contain spices such as chili, pepper, onion, ginger, garlic, cumin, and Chinese herbs, which are irritating and may cause gastrointestinal discomfort after consumption, and may be confused with adverse reactions to the vaccine, thus affecting post-vaccination observation and subsequent vaccination. After vaccination, it is important to ensure a healthy diet and good living habits, try to eat a light diet, and eat foods rich in protein, vitamins and carbohydrates, such as cereals, lean meat, vegetables and fruits in appropriate amounts, which are conducive to replenishing physical energy, ensuring the normal operation of the immune system and achieving a good immunization effect. In addition to hotpot, patients are also not recommended to drink alcohol, which can have an effect on various functions such as the brain.

At the same time, ensure sufficient sleep, avoid staying up late, sufficient rest is conducive to the smooth production of antibodies, so as to play a faster role in immunity.
