How long will it take to develop a vaccine against HIV / AIDS?
Despite continued intensive research, experts believe it will be at least a decade before we have a safe, effective and affordable vaccine against HIV. Even after a vaccine is developed, it will take many years before the lakhs of people at risk of HIV infection worldwide can be immunized. Until then, other HIV prevention methods, such practicing safe sex and using sterile needles and syringes, will remain essential.
