*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: https://www.statnews.com/2020/05/26/moderna-vaccine-candidate-trial-participant-severe-reaction/">https://www.statnews.com/2020/05/2... | @statnews

There& #39;s no failure here — this is a big reason why we do clinical trials. Doctors don& #39;t know the right dose ahead of time, and need to learn what& #39;s well tolerated.

Even safe meds can& #39;t be taken at 10x doses.

I haven& #39;t divulged all these details before bc:

1. For a while, it wasn& #39;t clear what happened to me.

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

3. It& #39;s hard to talk abt vaccine safety w/o triggering anti-vax ppl.

The symptoms I experienced weren& #39;t life threatening. They& #39;re over, and I& #39;m back to marathon training.

Vaccines are the single most important medicines we have. It& #39;s important to test them carefully — which is what& #39;s happening here.

I remain cautiously optimistic.

I& #39;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& #39;s what that pain can look like: https://youtu.be/U8q2IEj-j24 ">https://youtu.be/U8q2IEj-j...
