Special antibodies could lead to HIV vaccine. Around one percent of people infected with HIV produce antibodies that block most strains of the virus. These broadly acting antibodies provide the key to developing an effective vaccine against HIV. Researchers have now shown that the genome of the HI virus is a decisive factor in determining which antibodies are formed. Source 9r.
Scientists unveil promising new HIV vaccine strategy. A new candidate HIV vaccine surmounts technical hurdles that stymied previous vaccine efforts, and stimulates a powerful anti-HIV antibody response in animal tests. The new vaccine strategy is based on the HIV envelope protein, Env. This complex, shape-shifting molecule has been notoriously difficult to produce in vaccines in a way that induces useful immunity to HIV. Source 9d.
It has been so long since the worry of AIDS broke out in the 80s and yet we are almost at 2020 and still trying to figure out a vaccine for it. This is slow progress to me considering the amount of time and resources pumped into it.
HIV vaccine protects non-human primates from infection. New research shows that an experimental HIV vaccine strategy works in non-human primates. In the study, rhesus macaque monkeys produced neutralizing antibodies against one strain of HIV that resembles the resilient viral form that most commonly infects people, called a Tier 2 virus.
