The primary goal of the present review is to assess the limitations of current evidence and to provide I framework for additional research. RESULTS: There is a paucity of knowledge regarding the relative value of prophylactic influenza vaccination in HIV-positive adults compared with immunocompetent populations. There are shortcomings related to study methodology and temporal changes in the characteristics of patient baseline immune status, which limit the utility Of this information to Shape public health policy.
