Whether or not you can drink milk after the new crown vaccine depends on your own situation and varies from person to person. If you are not allergic to milk and you are not allergic to milk, you can usually drink milk after the vaccination, but if you are allergic to milk, it is not recommended. After the new crown vaccine, you should generally avoid foods that may cause allergies, such as milk, soy products, mangoes, seafood, etc. This is because once allergies occur, it will increase the chance of adverse reactions to the vaccine and aggravate the allergic reactions, and in severe cases, anaphylaxis and laryngeal edema can occur, which may be life-threatening if not seen in time. In addition, the occurrence of allergic reactions is also easily confused with the symptoms of adverse reactions to vaccines, making it more difficult to confirm the diagnosis and rescue of the disease. In addition, it is also necessary to avoid spicy and irritating foods, such as alcohol, chili peppers, scallions and garlic, because spicy and irritating foods are stimulating and can dilate blood vessels and increase the permeability of blood vessels, which may increase local adverse reactions after the injection, such as redness, swelling, hard nodes and pain at the injection site. After the vaccination, in addition to dietary attention, it is necessary to pay attention to more rest, avoid strenuous exercise, and keep the injection site dry and hygienic to avoid infection.
