It is not recommended to take a bath after vaccination. If you forget to take a bath after vaccination, you must closely and strictly observe the patient’s condition. When rubbing in the bath, it is necessary to pay attention to whether there is redness, swelling, heat and pain around the site of vaccination, and if the above symptoms appear, it proves that the site of vaccination is infected. In this case, the patient should be disinfected with iodophor, alcohol and saline and then dried naturally, and observe whether the patient has a fever.
