Booster shots are usually referred to as New Crown Vaccine booster shots, and spicy food is not recommended after the shot. The antibody titer in the body is decreasing over time after the new crown vaccination, and the defense is enhanced by another booster vaccination. In general, spicy food is not recommended after a booster shot of the new crown vaccine, mainly to avoid the occurrence or aggravation of adverse reactions. The booster shot may cause adverse reactions in some people, such as nausea, vomiting, stomach pain, loss of appetite, etc. Therefore, in principle, it is recommended to avoid spicy and irritating foods, especially ingredients such as chili peppers and ginger, in order to avoid aggravating the discomfort. In the short term after the booster injection, you should also pay attention to not drink alcohol, avoid strenuous exercise, and avoid rubbing and squeezing the eye of the needle; if there are serious adverse reactions such as fever, vomiting, or rash, you must consult a doctor as soon as possible, and a professional physician should make appropriate treatment to avoid adverse consequences.
