unit 4 vaccines Flashcards
composition of killed/inactivated vaccines
killed/inactivated
use/effectiveness of killed/inactivated
lose virulence and instead provides immune response
–> flu shot, rabies
composition of live-attenuated vaccines
contain alive mutant form of pathogen that grows poorly in humans (or are no longer pathogenic)
use/effectiveness of live attenuated vaccines
provides best protective immunity as it matches natural infection (enough to stimulate response but not cause an infection)
–> MMR, chickenpox
composition of subunit
purified single of mixed components (proteins/polyssacharides)
–> these components are the more immunogenic part that will stimulate strongest immune reaction
use/effectiveness of subunit
toxoid (tetanus)
–> antibodies produced against all components
composition of conjugate vaccine
protein-polysaccharide complex
–> on their own polysaccharides cannot active T helper cells so they need complex
use/effectiveness of conjugate vaccines
when linked stimulates T cell activation and results in immunologic memory
–> meningococcal and Prevnar 13
