Whether or not you can drink coffee after the New Crown vaccine needs to be analyzed on its own merits. If there is an adverse reaction after the New Crown vaccine, such as dizziness or headache, it is generally not recommended to drink coffee. If there are no uncomfortable symptoms, you are usually in good health and drink coffee regularly, you can drink coffee in small amounts at this time. After the injection of New Crown vaccine, the body’s immune system is activated and the corresponding antibodies are produced. At this time, patients may have some adverse reactions, such as weakness, dizziness, headache, etc. Since coffee is a stimulating drink, drinking it at this time may cause stimulation to the body and thus aggravate the adverse reactions of the vaccine. At the same time, caffeine contained in coffee can play a role in refreshing and promoting digestion to a certain extent, and some people may have headache and diarrhea after drinking it. If coffee is consumed after the injection of New Crown vaccine, it is difficult to identify whether it is caused by adverse reactions to the vaccine or coffee when the above symptoms occur. Therefore, if the vaccinated person is usually weak, it is recommended that he or she not drink coffee after the New Crown vaccine in order to avoid discomforting symptoms. If there are no uncomfortable symptoms after the New Crown vaccination, and if the person is usually in good health and drinks coffee regularly, he or she may drink coffee in moderation after the New Crown vaccination in order to improve the efficiency of study and work. In addition, you should pay attention to rest and avoid overexertion after the New Crown vaccination. Avoid getting water on the needle holes for a short period of time to avoid bacterial invasion, which may lead to infection.
