IDK. All I know is India dropped HCQ and ivermectin months ago because there was no benefit in treating covid patients.
India was providing it to nearly everyone prophylactically ... and their case rate was the lowest in the hemisphere. oh wait, you're a flat earther ... ah ... the lowest in their part of the disc.
Ivermectin may not be as effective when given on the timeline of treatment by the US Govt. I know nebulized budesonide protocol has been administered to folks on ventilators for weeks ... successfully. many times.
