Principles of Immunisation Flashcards
1
Q
What is active immunisation
A
brought about by a foreign antigen triggering an adaptive immune response within the body
creates immunological memory
initial response is slow but provides quicker defence against recurring infections by the same pathogen
2
Q
examples of vaccines for active immunity
A
live organisms (Attenuated) MMR or BCG
killed organism
toxid
recombinant - genetically altered, antigen coding gene is removed and replaced into yeast chromosome
conjugate- antigen as a carbohydrate is bound to a protein ie, strep Pneumoniae, Neisseria Meningitidis, Haemophilus Influenzaem

Q
What is passive immunisation
A
gives quick and immediate protection but does not create memory
involves inoculating the patient with antibodies specific to the pathogen
