VACCINES Flashcards
(14 cards)
What are the 3 types of vaccines?
Inactive, attenuated (live) and mRNA
Explain the inactive.
Inactive is when only the antigens of the infectious agent is used in the vaccine. the vaccine doesn’t contain any infectious antigen
Explain Live (attenuated)
The cultures of the infectious agent is chemically treated. it contains a live infectious agent
Explain mRNA
The mRNA provides cells with instructions to make the spike protein (it’s harmless) and it’s fond on the surface of the virus
The individual cells maek the spike protein
An immune reaction is prompted by the presence of the spike protein, so the WBC’s secrete antibodies
Next time the body is expose to the virus, it can protect itself
In thsi type of vaccine the infectious agent is still aLIVE
Live(attenuated)
The vaccine is made from antigens of the infections agent..
Inactive
The vaccine triggers a weak immune respinse
Inactive
The vaccine is made from whole samples of the infectious agent
Live
THe infectious agent undergoes chemical treatment to make it harmless
Live
The infectious agent is treated to identify and isolate a part of parts of it
inactive
give me 4 characters of the mRNA vaccine
mRNA doesn’t replicated
mRNA doesnt interact with genome
mRNA decays within a few daus after injection
mRNA is an unstable molecule so it needs proper storage: kept frozen in low temp.
Is vaccine natural or artificial?
It’s artificial.
Difference?
You don’t get sick because the bacteria/virus is attenuated.
definition of a vaccine
It’s a prepared substance that when injected will immunize the organism against the infectious agent
