I have to write a HIV vaccine research proposal for my assignment.

"Explain in detail the relevant results of the recent peer-reviewed key article(s) of your choice to understand the choice of the vaccine and the adjuvant. Select, show and explain only the relevant data from the article(s) of your choice. Explain why you think the vaccine and adjuvant of your choosing can lead (after further development as described in your plan of investigation) to a promising new or improved vaccine."

Any suggestions for promising vaccine strategy or candidate vaccines that needs improvements?
