Rapid development of an inactivated vaccine for SARS-CoV-2

I posted this here, although it's a preprint, because it mentions that the inactivated vaccine does not seem to cause antibody-dependent enhancement (ADE), which was one of the unknowns of the development of SARS-CoV-2 vaccines.

From the preprint:

> No antibody-dependent enhancement of infection (ADE) was observed for any vaccinated macaques despite the observation that relatively low NAb titer existed within the medium dose group before infection, offering partial protection.
