- Inactivated vaccines present killed pathogen material
- Live-attenuated vaccines use a weakened pathogen
- Viral-vector vaccines deliver instructions for a target antigen
- Subunit vaccines present selected pathogen components
- DNA vaccines supply genetic instructions for antigen production
- mRNA vaccines provide a protein-production template
- Covishield illustrates transferred viral-vector technology and Indian manufacture
- Covaxin illustrates Indian inactivated-virus vaccine development
- Cadila’s 2021 candidate illustrates the DNA-vaccine approach
