I think the verdict is too quick to dismiss the broader context. The claim isn’t just about whether ivermectin works on COVID—it’s about the logic that if it works on other RNA viruses, it *should* work on this one. But the real question is whether that logic is flawed, not just whether the drug has been proven effective in trials. The verdict focuses on the pharmacokinetic gap, but it doesn’t address why that gap exists in the first place. If the mechanism is sound, why can’t we find a way to bridge that gap? And if we can’t, does that mean the mechanism is flawed or just the delivery? The verdict assumes the gap is insurmountable, but that’s a leap. It’s possible the problem isn’t the science—it’s the way we’re applying it.

**ORIGINAL CLAIM:**
> "Ivermectin works generally across single-stranded RNA viruses and it would be weird if it didn't work on COVID"
— **Bret Weinstein** at 2:01:18
Topic: Ivermectin efficacy

**VERDICT: FALSE**
*In vitro mechanism fails at pharmacokinetic barrier; no clinical efficacy demonstrated.*
**Confidence: 92%**
📊 7 sources analyzed | 5 peer-reviewed | 3 debate rounds | 20 rebuttals

**WHY IT FAILS:**
• Required drug concentrations are 20-50x higher than safely achievable in humans.
• Zika precedent proves in vitro RNA virus activity doesn't predict in vivo efficacy.
• No clinical success demonstrated for any RNA virus despite decades of use.
**WHAT'S TRUE:**
• Ivermectin does demonstrate in vitro antiviral activity against multiple RNA viruses through importin α/β inhibition.
• The mechanistic hypothesis of host-directed therapy targeting conserved cellular pathways is theoretically sound.
• The biochemical mechanism of nuclear transport inhibition is real and well-documented in laboratory conditions.

**THE DECISIVE EVIDENCE:**
**1. PHARMACOKINETIC IMPOSSIBILITY**
Study demonstrated that ivermectin's in vitro antiviral effects occur at 2-5 μM concentrations, but standard human dosing produces plasma levels 20-50 times lower than required. This pharmacokinetic barrier makes in vitro observations clinically irrelevant regardless of mechanistic plausibility.

**2. ZIKA PRECEDENT: IN VITRO DOESN'T PREDICT IN VIVO**
Despite strong in vitro activity against Zika virus through the same importin inhibition mechanism, ivermectin showed complete lack of efficacy in murine models. This directly undermines the inductive inference that in vitro RNA virus activity should translate to COVID-19 efficacy.

**3. CLINICAL TRIALS SHOW NO BENEFIT**
Systematic review of high-quality RCTs concluded that despite theoretical mechanisms, ivermectin did not significantly influence critical clinical outcomes in COVID-19 patients including mortality, hospitalization, or viral clearance.

Discussion
The verdict doesn’t ignore the mechanism—it points out that even a sound mechanism can’t overcome biological reality when the drug doesn’t reach effective concentrations in the body. The question isn’t just about *if* the mechanism works, but *if* it works in practice.
