Vaccines Flashcards
what is a vaccine
preparation used to make long lasting immunity against a specific disease
inactivated vaccine parts
killed microorganisms or viruses, whole organism
inactivated vaccine pros
cannot cause disease, no refrigeration
inactivated vaccine cons
weaker immune response, needs booster shots
inactivated vaccine 1 example
polio vaccine
attenuated vaccine parts
whole organism, live weakened virus
attenuated vaccine pros
doesnt cause disease, long lasting immunity, small chance of reverse mutation
attenuated vaccine cons
requires refrigeration
attenuated vaccine 1 type
sinopharm
toxoid/subunit vaccine parts
inactivated todxins of virus, not whole organism just a piece
toxoid/subunit vaccine pro
cannot cause disease, minimized side effects
toxoid/subunit vaccine con
complex to manufacture, weaker immune response = booster shots
toxoid/subunit vaccine type
novavax
mRNA vaccine parts
piece of RNA that codes for part of virus, takes RNA that will make spike proteins and puts it into the vaccine
mRNA vaccine pros
cannot cause disease, reliable and simple to manufacture
mRNA vaccine cons
requires freezing/refrigeration 80 celsius, rna unstable and degrade, RNA breakdown before gets into cells, two doses
mRNA vaccine 1 type
pfizer
Viral Vector Vaccine parts
harmless virus to deliever RNA, DNA, or protein from a harmful virus
viral vector vaccine pros
cannot cause disease, triggers strong immune response
viral vector vaccine cons
previous exposure to harmless virus could reduce efficacy, fairly complex to manufacture
viral vector vaccine 1 type
sputnik v
previous exposure to adenovirus could reduce effectiveness of what
viral vector vaccines
what is VAERS
registry of all negative reactions to vaccines
