No offense, but you should seriously try to lose weight. About 78% of Covid deaths occurred in ppl who were obese or seriously overweight. Losing weight would be far more efficacious in fighting Covid than a vaccine IMO.
I have eaten salad for lunch and dinner every day for the past 2 weeks. The problem I have is that I have two blown out disks in my back. Ever had blown out disks? Not a great time. Hell, I used to run 5 miles a day. I can barely walk a mile and a half now. Coughing and sneezing will about put me on my knees. If I got Covid, it would be the death of me.
