Meh. Make sure plenty of zinc gets in your cells and you’ll be fine.
My stomach can’t tolerate zinc supplements. Sorry to say. But as for the mutations, my understanding was that current vaccine development was focused toward a “base” or foundation of sorts that can be reengineered toward future mutations. It’s been several months since I read that so I can’t provide the link, or I would.
Similar to the flu vaccine....which I also get every year. :)
It only matters if you are trying to sell a vaccine.
