Many current studies focus on developing vaccines that might not completely prevent HIV infection, but that still could slow the progression of HIV or make a person less likely to pass the virus on to others. But our ultimate goal is to develop a vaccine that can prevent HIV infection.
当前的许多研究集中在开发可能并不会完全预防HIV感染、但是仍然能够减缓HIV病毒的发展或者使一个人不那么可能把病毒传染给其他人的疫苗上。但是我们的终极目标还是开发出一种能预防HIV病毒感染的疫苗。要取得成功，我们必须解决怎样诱导人体产生保护性免疫反应的难题。
