Yep.

My protocol all last year and through the winter was:

Vit-C/Vit-D/Quercetin/Zinc.

I was exposed more than a DOZEN times I'm absolutely certain of and did NOT get infected. I had antibody tests and was negative through the whole thing (I'm now out, oh well.)

These are all very, very low risk since they're nutritional supplements. Vit-D don't go crazy with as it is possible to reach a toxic blood level (and if you do its BAD); ditto with the zinc.

Vit-D is less of an issue if you get a decent amount of sun exposure in the summer, but a whole lot of people don't and if you've got long clothing on then you're not getting enough, period, never mind that outside of the summer months if you're anywhere north you almost certainly DO and thus even if insolation was sufficient, and it isn't, you're all covered up!
