In general, on the day of vaccination with the new crown vaccine, a small amount of spicy food does not produce uncomfortable symptoms in the vaccine recipient and the vaccine does not expire. However, due to differences in individual constitution and absorption of the vaccine, excessive consumption of spicy food generally does not affect the immunization effect of the vaccine, but may aggravate the adverse reactions caused by the vaccine. Therefore, eating large amounts of spicy food on the day of vaccination is not recommended. The vaccine itself may cause redness and pain at the vaccination site and symptoms such as fever, weakness, nausea and loss of appetite in some people, while spicy food may stimulate the gastrointestinal tract and digestive system, which may lead to aggravation of uncomfortable symptoms, confusion with adverse reactions to vaccination, and affect normal life. Therefore, it is generally recommended to eat light, less irritating and easily digestible food for 2-3 days after vaccination, and you can drink more warm water and consume more fresh fruits and vegetables, etc. Usually, the diet can be gradually returned to normal after 1 week, and spicy foods can be consumed appropriately. If some patients have mild symptoms after eating spicy food on the same day, they can be temporarily observed, and if the symptoms continue to get better or worsen, they should actively contact the vaccination site to determine whether further treatment is needed. In addition to not recommending the consumption of spicy and irritating food, patients are also not advised to take a bath after receiving the new crown vaccine to avoid causing infection at the vaccination site. Exercise can be performed appropriately, but avoid strenuous exercise to avoid increasing blood flow and causing uncomfortable symptoms. If adverse reactions occur after vaccination with New Crown vaccine, you should not take medication to relieve yourself to prevent the interaction of different medications and vaccines.
