CRISPR may not work in some people

CRISPR, the precision gene-editing technology researchers hope can be used to treat genetic illnesses, may be ineffective or even dangerous for a large subset of humans, according to STAT news. A new paper reports many people may be immune to the two most commonly used types of CRISPR. However, some scientists told STAT it may be possible to work around this problem.

Why it matters: We're moving closer to using CRISPR in human trials, but if the results of this paper are confirmed (it hasn't been peer reviewed yet) it's possible the treatment could be stopped by the immune system, or worse, trigger a dangerous inflammatory immune response.
