there's a lot of genetic variation in HIV due to natural selection. in the process of replicating they make many different strains -- mostly very similar to one another. here is an HIV sequence database https://www.hiv.lanl.gov/content/index https://www.hiv.lanl.gov/content/index https://hivdb.stanford.edu/page/who-resistance-list/ https://hivdb.stanford.edu/page/who-resistance-list/ if you take medicine, get off them and try to get back on your medicine, you may find your medicine no longer works. that being said I don't quite know what "neutralize" means in this context, but the NIH seems to feel this result has wide applicability.
