All antibodies mean is his immune system can recognize and react to the virus, that doesn’t mean his mickey D’s fueled immune cells are up to the task
Yes, I can almost guarantee you they are.
Immunosenescence is almost ENTIRELY about the loss of a flexible adaptive immune system, losing the ability to make fine tuned antibodies that fit viral antigens perfectly, these are mostly B cells and CD4 T cells, thymal age atrophy is a big part of the latter (CD8 cytoxic T cells are almost always fine)
Literally everybody (excepting a few genetic conditions) have normal levels of these "blast them away" type immune cells that you're imagining. Neutrophils and macrophages.
