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.

As for the effects it depends on how much damage has been done already. The very likely scenario is that he will suffer no damage from here on out.
