Can I take a shower after receiving a vaccination?

Whether or not one can take a shower after vaccination depends on the time elapsed since vaccination. Generally, showering is not recommended within 24 hours after vaccination; however, showering is usually permissible after 24 hours. Within 24 hours after vaccination, showering is generally not advised. If the injection site accidentally comes into contact with contaminated water, microorganisms may enter the subcutaneous tissue through the puncture site, leading to local infection and symptoms such as itching, redness, swelling, and pain. In severe cases, abscesses may occur. Within 24 hours after vaccination, it is important to keep the injection site clean and avoid contact with unclean substances. After 24 hours post-vaccination, the puncture site typically heals adequately, and showering generally does not cause infection at the injection site, so normal showering is acceptable. It is important not to vigorously rub the injection site, as this may cause further injury. After vaccination, it is important to take proper precautions and monitor your condition. If discomfort such as fever or pain occurs, seek medical attention immediately.
