Is Gene Drive Research Losing Traction? [PDF]

open access: yesAm J Trop Med Hyg
ABSTRACT. Significant progress has been made in developing gene drives, especially for mosquito vectors of malaria. It is widely agreed that a critical next step in advancing this technology is to evaluate it through small-scale field trials. However, obtaining permission to move forward with these trials has stalled, threatening this potentially ...
