Wow, based on your experience, I am sold on this investigational therapy for a virus with about 99.7% survivability. (Not)
Thankfully I am keeping my vit D levels up and taking daily zinc. I stopped having colds since I got into this routine!
Good that you are taking Vitamin D and supplementing with Zinc. They are a good way to improve your odds in the function of your immune system.
I think getting the vaccine will prevent you from being as contagious as someone without. Maybe as time goes on they will discover vaccines do better at prevention than we think. I am always in favor of improving my odds.
Zinc supplementation:

However, it is tricky to know what the safe dose of zinc if you are planning to take large daily amounts. I say no more that 20 mg daily and let your hamburger and oyster consumption make up any extra you need.
