It's really interesting. I mean... I was consulting a professional. It began with "do you require masks in your office... are you comfortable being within six feet." As she started to trust me, she confided in me that she had one dose of the vaccine. And it made her so sick she decided not to get the second dose. And she felt like garbage until she tried some natural herbs that cleaned her system out. We trusted each other a bit more after that.

So that might be part of the under use.
