We will test the effectiveness of mesotherapy as a vehicle for influenza vaccination.We will use 1:10th of the amount of seasonal trivalent influenza vaccine in approx.50 HIV/AIDS patients.A control group of approx.50 matched patients for age ,treatment schedule and immune status will receive the regular injection of trivalent vaccine. We will follow patients clinically for symptoms compatible with seasonal influenza and for direct side effects of the vaccine.In addition we will measure anti influenza antibody in the two groups .Follow up will be for 6 months following vaccination.Anti influenza antibody will be measured at 1,3,6months using hemagglutination inhibition (HAI) test.
