what is immunity?
resistance to infection by a pathogen
can be acquired naturally artificially actively and passively
natural passive immunity
blends the antibodies for example through breast milk
active passive immunity
exposed to the pathogen - immune system triggered and produce antibodies/memory cells
artificial passive immunity
antibodies injected into the body
artificial active immunity
vaccines which trigger body to produce antibodies and memory cells
specific immunity
body produces memory cells specific to the pathogen (antigen) which can trigger production of specific antibodies to specific antigen
herd immunity
need a large percentage of the population vaccinated against a particular pathogen
who
world heath organisation
why is active immunity better then passive body
it lasts for a longer period of time
the body has gone through the entire immunity response and has produced the required antibodies and memory cells for if you are infected again with the same pathogen
what do vaccinations do
stimulate the bodies immune system/response to produce the antibodies and memory cells
do you develop symptoms with vaccines
generally you do not
benefits of vaccines
less vulnerable from the disease (protected)
produce herd immunity
risks for vaccines
potential for adverse reactions
possibility of getting the disease
why do antibiotics not work for viruses
because viruses are not a living cell
macrophages\phagcytes
engulf bacteria and foreign particles that attempt to enter the body and then destroy them
