Questions about an immune response to viral infection. When exactly do we make antibodies? Does it occur right after an APC has connected to a CD4+ cell which sends "help" in the form of cytokines to CD8+ cells. CD8+ cells profiliferation process has increased and they fight off a viral infection by causing cell apoptosis. Does it mean that CD4+ cell also sends cytokines and attaches to a B cell which then starts producing plasma cells/ memory cells and antibodies? If that is true, then why do we need antibodies for a viral infection since viruses can't survive without a host cell and these antibodies are just floating around in the blood stream and can't target viruses?

Thanks!
