What could be another reason [they] so scared of hydroxychloroquine?

Nanoparticles are used in DARPA and Gates funded Moderna's RNA human gene editing VACCINES 👀

"It has been demonstrated that chloroquine is a broad-spectrum inhibitor of nanoparticle endocytosis by resident macrophages. Therefore, chloroquine decreases the accumulation of synthetic nanoparticles of various sizes (14–2,600 nm) and shapes (spherical and discoidal) in cell lines, as well as in the mononuclear phagocyte system of mice in response to clinically relevant doses of chloroquine"
