With multiple coronavirus vaccines being produced as we speak, the COVID-19 pandemic appears to have an end in sight, though the HIV pandemic continues after more than 40 years. That might seem like a head-scratcher: why is HIV, a virus we’ve known about for decades, so much harder to cure than a virus discovered just last year? Part of the reason is that HIV, as a retrovirus, is a more complex virus to vaccinate against than SARS-CoV-2 — hence why a vaccine or other cure has eluded scientists for decades. 

Now, a surprising new study on a related retrovirus shows incredible promise for the potential to develop a cure for HIV, or human immunodeficiency virus. In an article published in the scientific journal Nature Communications, scientists revealed that they had used CRISPR – a genetic technology that can alter DNA and whose developers won the 2020 Nobel Prize in Chemistry — to successfully edit SIV (simian immunodeficiency virus), a virus […]
