After vaccination, vaccinees need to stay and rest. At the same time, the vaccine can only play a preventive role and cannot treat the disease, nor can it guarantee a 100% protective effect for all vaccinees, so you should protect yourself in life. After vaccination, it is advisable to have a light diet and avoid greasy and high-sugar foods, such as cakes and fried foods, etc.: 1. Take a good rest and avoid overexertion and strenuous exercise; 5. If there are symptoms such as redness, swelling, pain, and transient fever at the vaccination site, they are normal adverse reactions to vaccination and can be observed at rest. If the symptoms are serious, it is necessary to seek medical attention promptly; 6. If you receive multiple doses of vaccination, you should keep in mind the next vaccination time to avoid delaying the vaccination and causing the vaccine to become invalid. Dietary advice: 1. Avoid spicy and stimulating food: eating spicy and stimulating food soon after vaccination may also induce or aggravate adverse reactions to the vaccine, so it is recommended to eat again after about 5 days; 2. Avoid alcohol: as alcohol may easily induce adverse reactions to the vaccine, it may also lead to aggravation of the degree of adverse reactions and affect the preventive effect of the vaccine at the same time, so it is recommended to drink again after about 5 days; 3. Avoid foods that are easily allergic: such as sea fish, sea shrimp, beef and mutton, etc., which can cause allergic reactions and affect the function of the vaccine in the body.
