Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Zostavax is a live vaccine used to prevent herpes zoster virus (shingles) in people aged 60 and older. Common side effects of Zostavax include: (i) Injection site reactions like redness, itching, swelling, warmth, bruising and pain (ii) Headache (iii) Diarrhea (iv) Joint or muscle pain (v) Skin rash. However, these side effects should subside with supportive treatment. In case the symptoms do not subside and become bothersome, kindly consult your doctor for evaluation and appropriate management. Hope I have answered your query. Let me know if I can assist you further.
