For the approximately 37 million people worldwide who are infected with HIV (human immunodeficiency virus), the newest cocktails of anti-retroviral drugs have come a long way in beating back the retrovirus and keeping an infection in check. Still, those drugs are no cure. While the treatments snarl the viral assembly line and thwart new infectious particles from invading the body’s cells, HIV itself is still there, hunkered in the DNA of a patient’s genome until there’s an opportunity for a comeback—say, when a patient goes off their medication.

I wonder if this means if we can eventually cure all those pesky viruses that hides in cells. Shingles, Herpes, and the whole bunch.
With genetic tweaks and snips, researchers created cancer-busting immune cells that, so far, seem to have wiped out a life-threatening form of leukemia in a one-year-old girl.
The new cells are one-size-fits-all, beating out earlier cell-based cancer therapies that required custom engineering of each patient’s own immune cells. If proven effective in more trials, the new, generic cells could offer an easy, off-the-shelf treatment for life-threatening forms of leukemia.

Fingers crossed. Nobody – and certainly no child – should have to suffer cancer.
