One of our relatives was exposed to agent Orange in Nam and has been on some special program for decades at a Vet Hosp..
He is in his mid 70’s and seems to be in great health and does all type of exercise from Pickleball, tennis doubles to walking, slow running and a few minutes each day of minimal weight lifting.
We get the feeling that his official Agent Orange treatment does not include any Covid shots.
Sounds great. I would not have taken the Moderna shots, but I usually trusted what the VA had for vaccines. Also, I volunteered at the local VA center and require at least the flu shot every year.
