Did COVID come from a lab? Metzl, Collins and Jacobsen on origins
October 13, 2026 · 29 min read
Jamie Metzl lays out a circumstantial case for a lab-related origin in Wuhan and criticizes the WHO investigation, NIH director Francis Collins answers questions on whether COVID-19 could have leaked from a lab and what gain-of-function research means, and Annie Jacobsen takes up COVID's origins, the Fauci hearings and the oversight of laboratories. Setting an advocate, an official and a journalist side by side shows what the origin argument rests on and why oversight of risky research is the practical question it leaves.
The rules, numbers and steps worth keeping in front of you.
- None of the three conversations settles the origin of COVID-19, and none presents direct proof.
- Metzl: roughly 85% for an accidental lab incident in Wuhan, with all evidence on both sides circumstantial.
- Collins: cannot exclude a lab leak, thinks it fairly unlikely, and expects the answer from finding an intermediate animal host.
- Collins's precedent: the host of the first SARS, the civet cat, took 14 years to identify.
- Jacobsen: every subject matter expert she interviewed encouraged her to write that it was almost certainly a lab leak.
- Metzl separates two claims: the origin is debatable, the cover-up is not.
- Check the definition of gain of function first. Collins means enhancing the transmissibility or virulence of a known human pathogen with pandemic potential.
- Similarity numbers: Collins cites NIH-funded bat viruses about 80% similar to SARS-CoV-2; Metzl cites RaTG13 at about 96.2%.
- Evidence that would move Metzl: a full audit of the Wuhan lab's viruses, the missing database of about 22,000 samples, early case data.
- Jacobsen: highest-containment laboratories went from two to roughly fifteen in the United States, and well over a hundred worldwide.
- Jacobsen: the Biological Weapons Convention has no enforcement mechanism, and containment depends on the first twenty-four hours.
- Collins: the original SARS escaped from labs in China two or three times, so accident risk must be factored in.
- Not medical advice: for decisions about your own health, ask a doctor who knows your situation.
This is the short form. The full insight has every expert's reasoning, their own words and the sources.
