Will you let me look at the details of that?

I mean, if you're not going to be able to answer it right now I don't want to waste our time.

I'm talking about this afternoon. Yeah, please.

Okay. I just want to make sure that we get to everything. Early in 2020, did you ever have any concerns about the safety of SARS-CoV-2 vaccines that were being developed?

We don't really have to. We'll look it up.

Okay. So basically there's a massive inflammatory response that has the potential to be lifethreatening, and the SARS coronavirus vaccines, from 2003, that the NIH had purchased, were both adjuvanted with alum. And we published papers showing that that drives a strong Th2 immune response. So my concern, and I expressed this to the WHO and to other groups, was that we needed to look carefully for vaccine-induced immune pathology. Ultimately, we published a paper with the VRC. That was one of the experiments we set up to do, where we took mRNA vaccines and we took killed vaccine preparations with alum and compared them head-to-head for the ability to induced Th2 responses. The mRNA vaccines did not cause it. The recombinant protein, or the killed vaccines plus alum caused a big Th2 response. Now, the Chinese vaccines were killed vaccines with alum, which I think was inappropriate. The mRNA vaccines, though, were tested for that using homologous virus challenge.

Okay. So at this point --

At that point, the downstream question is whether if you have significant amounts of virus variation and you're infecting the original Wuhan mRNA vaccine, will breakthrough infection induce an immune pathology phenotype, and those are the kinds of things we're interested in studying now.
