You should not touch water within 24 hours after rabies vaccination to avoid local infection and even sepsis. Although the eye of the vaccine is small, it can also cause damage to the body, resulting in a decrease in the barrier function of the skin mucosa. After vaccination, it usually takes one day for the needle eye to recover, so it is best not to let the needle eye touch water during that period. After vaccination, patients need to stay in the hospital for 30 minutes to avoid adverse reactions to the vaccine and wait until they do not feel any discomfort before leaving. In addition, patients should pay attention to the local cleanliness of the eye of the needle, and if special circumstances make it necessary to touch water, the eye of the needle can be protected with a waterproof adhesive patch. The patient should pay attention to a light diet and avoid strenuous exercise, drinking alcohol and strong tea to help the body produce antibodies against rabies virus.
