It's been 3 years. By now, you'd think at at least thousands of humans worldwide would be subject to studies.
Is it too early to test the effects in humans?

Not as many humans willing to let you take their brain out and poke around in it. And IRBs tend to get a little miffed if you trick people into it.

Human experiments are expensive and extremely time consuming because they have to pass the IRB board. They are often infeasible for many labs due to funding constraints. Studies like this often motivate the more expensive studies in humans.

I mean, researchers do research that fits them best. Maybe they didn't find voluntary participants and had to resort to monkeys? Just because one research team of 1 bazillion isn't doing it, doesn't mean others aren't doing that right now.

There have already been human challenge studies in the UK. They were exposed to a viral dose that was around a third of a million of what the monkeys in this study were exposed to.
