If a person manages to survive an Ebola infection
the immune system fights the virus by making
highly specific antibodies against it. These
antibodies bind to the viruses and mark them for
the immune system (mainly through mast cells) for
take-up and degradation while inhibiting them from
infecting other cells. Serum from Ebola survivors
has been used as experimental treatment for
infected people (here mainly the antibodies can be
helpful). People who survive the infection are
immune against another infection of the same virus
strain.
