antibody, the Helper T-cell in your immune system will be triggered if it detects antigens.
it'll then produce interleukin , this chemical triggers the killer T-cell and plama cell from B cell.
The Killer T-cell will then produce cytotoxin to kill the pathogen which some may attach on the surface of macrophage on the MHCII.
Antigen is destroyed , B cell then produce memory cells for the next invade of the same pathogen.
So , you see ? human's immune system is awesome. It make you immune to it. and eventually it has no effect when the pathogen invade ur body again.
So , be optimist !
nothing is gonna bring you down ( unless you've poor immune system LOL )
