Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Shingles vaccine may cause Fever, lymphadenopathy and body aches. Rarely it may cause vaccine induced rashes. Other possibilities like folliculitis or boil etc. Until examination is done it is difficult to say what it is. Please consult your doctor he will examine and treat you accordingly. I hope I have answered your query. Let me know if you have any further questions. Regards, Dr. Penchila Prasad Kandikattu
