如果疫苗通过刺激人体产生数百个温和的抗体,联合作用,或许我们将更好地抵御HIV。臭名昭著的艾滋病病毒(HIV)是整个医学界的顽固对手,其变异速度超过了人体免疫系统的承受能力。尽管该病毒在25年前就被发现了,但直到今天,我们依然未能研制出有效的艾滋病病毒疫苗。虽然科学家已经研制出多种防止病毒入侵的抗体(antibody),但能够启动批量产生这种抗体的疫苗仅能在猴子

If the vaccine works by stimulating the body to produce hundreds of mild antibodies, we may be better off fighting HIV. The infamous AIDS virus (HIV) is a stubborn rival throughout the medical community whose rate of mutation exceeds the capacity of the body’s immune system. Although the virus was discovered 25 years ago, we have not been able to develop an effective HIV vaccine until today. Although scientists have developed a variety of antibodies against virus invasion, vaccines that are capable of initiating such antibodies in batches can be administered only to monkeys
