Generally, after vaccination, you need to stay for half an hour and leave without any obvious discomfort, after which you can go about your daily life normally without any special contraindications. However, there are some things that you should pay attention to, such as doctors usually advise you to take rest after vaccination, keep your wounds away from water and do not drink alcohol, etc. You should also pay attention to the adverse reactions after vaccination. The lighter transient reactions can be ignored, but if the symptoms are serious, you need to consult a doctor, so the main precautions can be referred to the following aspects: 1. During sleep, the body’s systems and organs will be in a relative state of rest, which will help the immune effect of the vaccine and help the body build an immune barrier; 2. Avoid getting wet: after vaccination, you should avoid contacting the wound with water and pay attention to keeping the vaccination site clean and dry, so that the germs carried in the water will not invade the body by the needle opening and eventually cause infection, and will also affect the immune effect of the vaccine; 3. Pay attention to diet: after vaccination, you should drink more water, although there is no absolute contraindication in diet, but also pay a little attention. For people with allergies, in addition to foods containing allergens, foods that may induce allergic reactions, such as alcohol and seafood, are not recommended for intake. This is due to the fact that it is not easy to distinguish between the vaccine and the allergic food in case of allergic performance; 4. Pay attention to adverse reactions: after vaccination, the human body may experience certain adverse reactions, such as muscle aches, body weakness, dizziness and headache. Minor discomfort can be temporarily observed and can basically recover on its own after a period of time. However, if the reaction is relatively severe, such as high fever, chills, etc., it is recommended to consult a doctor promptly and do not take medication on your own.
