Just want to let folks on this list know: I'm entirely for choosing what you want to put in your body if it doesn't harm others. I also support (and help run) dances who understand that immunology _is_ about harm reduction to the public. It's a complicated issue, absolutely. I don't think there is one universal solution for each dance series. However. I'm autistic, so are many callers, and so are many dancers. The Anti-vaxx movement in the US is heavily funded and tied to efforts that do not respect, patronize, harm, and ignore the wishes of autistic people. If your science isn't peer-reviewed and air-tight: 1. Autistic folks and their allies will likely regard this as a signal that you don't care about them, whether that was your intention or not. 2. It has previously been asked not to be in Shared Weight. So, can we please not? Julian Blechner
