Q

Inmune response caused by a virus infection and vaccination

Include Antibody production and cell mediaed immunity

A

When your body detects an antigen, it releases antibodies that bind to them, neutralizing it.
Cell Mediaded Immunity kills infected cell.
Antibody Mediaded Immunity neutralizes virus.

Q

RNA vaccines

How are they made

A

A transcription rxn is run with enzymes and RNA nucleotides to produce RNA from a plasmid DNA template. The RNA is then purified and encapsulate in lipid nanoparticles to protect it.
