Can I take a shower after getting vaccinated?

Under normal circumstances, if there are no abnormalities at the injection site and no physical discomfort after vaccination, it is safe to take a shower after 24 hours. However, if redness, swelling, hard lumps, or other discomfort occur, bathing should be postponed. If in doubt, it is recommended to consult a healthcare provider in advance. Detailed explanations are as follows:

If only mild numbness or soreness occurs at the injection site without redness, swelling, or discharge, and no systemic symptoms such as fever or headache appear, it is generally safe to bathe normally after waiting 24 hours. Avoid scrubbing the injection site with a bath towel; simply rinse gently with lukewarm water. After showering, gently pat the area dry with a soft towel to minimize the risk of infection.

If noticeable redness, pain, hard nodules occur at the injection site, or if systemic symptoms such as fever, fatigue, or nausea develop, bathing should be temporarily avoided. The skin at the injection site may have tiny breaks where pathogens could enter, increasing the risk of infection when exposed to contaminated water. Bathing while feeling unwell may also worsen fatigue. Wait until symptoms subside before resuming regular bathing.

After vaccination, closely monitor the injection site. Seek medical attention promptly if redness and swelling persist beyond three days or if fever exceeds 38.5°C. Additionally, if itching or fluid leakage develops at the injection site after bathing, contact a healthcare professional as soon as possible.
