Only now on April 9, 2020, after pushed by President Trump and after cases peak in the US, does the NIH begin a hydroxychloroquine clinical trial, but they only target hospitalized COVID-19 patients.

To date success with HCQ has been shown by frontline doctors in very early treatment with zinc, plus in 2005 NIH trial on SARS virus showed early in vitro treatment was necessary for Chloroquine to be effective.

On April 5, 2020, “Vice President Pence announced that a 3,000-person study on the effectiveness of hydroxychloroquine as a COVID-19 treatment would take place at Henry Ford Hospital.”  Which turned out to have a mortality benefit.

This is on the backlash over the promotion of HCQ.
