I have been around dairy cattle and calves that can be particularly nasty at times since my teens. Never been too particular about cleaning up until day's end. Haven't had a cold or flu for more than a day or two in years and have always laid that to a lot of immune system stimulation from my environment. Since knee replacements in 2015 I am supposed to take antibiotic before procedures like dental work or colonoscopy but never do. I figure it screws up your microbiome and that screws up your immune response. Looks like I must have plenty of good T-cells.
At least one of the COVID vaccines, Pfizer I think, has a T-cell response as well as an antibody response. Double barreled they claim.
