Immunology : The Immune system seeks out invaders that attack our bodies constantly
The Immune system must be able to
Recognize
Respond and
Remember the invader.
Immunity means you have protection, but before that you must have been attack by the virus to
be immune to it. E.g chicken pox, when someone is exposed to chicken pox virus for the first
time, after a couple of days the signs will appear (rash on skin) while the immune system is busy
fighting it off. After the person gets better the virus the immune system has the ability to create
the memory cells which carries the memory of the chicken pox virus forever. That’s why people
that previously had chicken pox rarely get it for the second time. Another example is through
vaccination, when we get vaccinated our immune system thinks we already have the virus and
builds a line of defense through the memory cells.
Memory cells allow Instant recognition to invaders and immediate response to those threats.
Transfer factors are memory molecule which educates our immune system the ability to
respond immediately because it recognize threats through those memory cells which act like
“wanted posters”
