i haven't done exhaustive research on this and I'm not a doctor, but...i think the common link between these is that the antiparasitics suppress the oppotunistics pathogens that gain control while your body is fighting off the primary SARS viral load. if you look back at research papers dating back to SARS and the conclusions about HCQ back then, i believe this was basically the conclusion about why it was effective against that variant and would logically be effective against SARS-Cov-2. except the media suppressed it, resulting in hundreds of thousands of unnecessary deaths and lockdowns
