Cytotoxic T cells are immune cells that can eliminate viral infections. (a) Briefly describe one mechanism whereby activated cytotoxic T cells can kill virus-infected cells.you need a flu shot every year/season because (HA-haemoagglutinin; NA-neuroaminidase) A) the virus can change its HA and NA every year, so a new shot is needed to teach your immune system how to recognize the changed HA and NA B) flu virus gets rid of its HA and NA and replace them with completely new ones every year C) your immune system weakens after a year-so you have to get another shot to get the system strong enough to attack the virus D)antigen shift occurs every year
