*deep breath*

So, I had a bit of an issue after getting my 2nd injection of a candidate COVID vaccine.

It was the highest dose — 10x what some others got. That high dose will no longer be tested.

I spoke abt it publicly for the 1st time: statnews.com/2020/05/26/mod… | @statnews
There's no failure here — this is a big reason why we do clinical trials. Doctors don't know the right dose ahead of time, and need to learn what's well tolerated.

Even safe meds can't be taken at 10x doses.
I haven't divulged all these details before bc:

1. For a while, it wasn't clear what happened to me.

2. I learned recently that 2 other high-dose participants may have had something similar.

3. It's hard to talk abt vaccine safety w/o triggering anti-vax ppl.
The symptoms I experienced weren't life threatening. They're over, and I'm back to marathon training.

Vaccines are the single most important medicines we have. It's important to test them carefully — which is what's happening here.

I remain cautiously optimistic.
I'll also note that what I went through pales in comparison to being hospitalized with COVID-19. Or to the pain of losing a loved one to the pandemic.

Here's what that pain can look like:
