Same. I hardly ever get sick. I never got flu vaccines and the one time I did was the most I ever had been sick.
As for covid, my girlfriend and I live together in a 1500 sq. ft. townhome. Impossible to isolate. She got covid, all the symptoms. She's fine now. Nothing ever happened to me.
Yeah I am the same way, almost never get sick (knock on wood) but am terrible with the flu vaccine so I don't take it. My thinking is out of every flu season that I have been in the USA I had the flu maybe once and it sucked, so 1:24 ratio. Every time I've taken the flu Vaccine including 'Rona I have been sick for at least 2 days. so, 5:5 ratio.
Now, the above stats are for me. I took the Pfizer Vaccine because I have kids that can't get vaccinated and interact with my in-laws and my Mom and don't want to be the one to get them infected. Please don't misread this as me saying that the vaccine is an end-all. The vaccine is a layer of protection and spread mitigation. Coming from a security background, when you secure your home, you don't call it "locked-down" by just locking the front door and leaving the windows and side doors open. You enable layers of protection by locking all doors + windows, drawing shades, turning on alarms, setting the perimeter booby traps, unleashing the hounds, initiate life model decoys, and activate the pain generators.
