Abstract
TB remains a global health challenge and, until now, only one licensed vaccine (the BCG vaccine) is available. The main goal of this work is to assess the progress in the development of new TB vaccines and highlight the research in nanovaccines. A review was conducted using a methodology with the appropriate keywords and inclusion and exclusion criteria. The search revealed 37 clinical trials that were further reviewed. The results available have reported good immunogenicity and safety profiles for the vaccines under investigation. Over the last five years, the vaccines, VPM1002 and Vaccae, have moved ahead to phase III clinical trials, with the remaining candidate vaccines progressing in phase I and II clinical trials. RUTI and ID93+GLA-SE involve the use of nanoparticles. This strategy seems promising to improve the delivery, efficacy, cost, and storage conditions of the existing TB vaccines. In conclusion, the use of nanovaccines may be an option for both prevention and treatment. However, further studies are necessary for the development of novel TB vaccines.
