Immunisations Flashcards
when do people get vaccinations (4)
childhood
elderly
before travel
occupational groups (eg healthcare)
which cells are involved in immunological memory and hence immunisation process (3)
memory B cells
memory T cells
long lived plasma cells
which antibody is the one that responds much quicker on secondary exposure of an antigen
IgG antibody
where are B cells made
bone marrow
‘B’ cells = ‘B’one marrow
what do B cells produce
antibodies
‘B’ cells = anti’B’odies
what is the function of T cells
orchestrate the immune response - bind to other cells, send out signals
what is a live attenuated vaccine
exposure to less virulent version of the same organism
what is an inactive vaccine
exposure to inactivated (‘killed’ or not) pathogen
which type of vaccines always need a booster immunisation
inactive vaccines
what type of vaccine is diphtheria
inactive toxoid
what type of vaccine is hep B
inactive subunit
what type of vaccine is influenzae
inactive subunit
what type of vaccine is tetanus
inactive toxoid
what type of vaccine is pertussis
inactive subunit
what type of vaccines are used for pneumococcus, MenC and hep B
inactive conjugate vaccine
what do you add in a conjugate vaccine
protein
why do you add a protein to a vaccine in conjugate vaccines
to make the vaccine more immunogenic
if a vaccine has a peptide/protein adjuvant, what is it known as
conjugate vaccine
