91% of HIV strains means we are 91% of the way to complete eradication.
That is inaccurate. Current antiviral agents remove most (as in over 90%) of the HIV viral particles from the blood of a patient. But then after weeks or months the viral load in blood is just as high. And any given patient has numerous strains within. Furthermore, most viral particles are not active: the virus saturates the immune system with defective particles (in a way it screens itself under noise). What's worse, HIV has long-term repositories like nervous system cells, from which particles are emitted at low rate. Killing your brain cells just to get rid of HIV defeats the purpose.
What this novel antibody will do is to remove 91% of the strains, meaning the remaining 9% will flourish enormously . RNA viruses mutate very fast and broadly (always being one step before crash-error).
What a good antibody can do is cut short the epidemics side of HIV: if a patient's HIV load is so low that it can't effectively and consistently pass on its infection to another person, the infection dies with the patient. This leads to a negative feedback loop that stops the epidemic. It's the same concept as vaccines: ensure that a sufficiently large proportion of the population is immune, so infections cannot spread when they inevitably appear in isolated individuals.
