This protocol utilized HCQ, zinc, and azithromycin. The study reports a very low fatality rate of 0.71% in treated patients with confirmed positive cases of COVID-19.

The existence and efficacy of this protocol should have invalidated any application for emergency use authorization of experimental vaccines. Dose of HCQ in the Zelenko Protocol was 200mg twice a day, which is a normal dosing level. Compare with dosing of WHO study, which used 5 to 10 times that amount.
