Right now, it's a complicated scenario where everything is pretty uncertain. We don't know what kind of other variants of the virus will appear, we don't know what the long-term effects are post-infection but we don't know those of the vaccine either.. it's all just an uncertainty and I think the worst thing I can do right now is take rushed choices..
What is quite clear is that general health plays a role, so for now I try to work on that, keep vitamins and minerals stocked up and try to vary my food more.
