Vaccine Ingredients and Types

Vaccines are made from:

1. Live or inactivated pathogens/germs
2. Polysaccharides
3. Toxoid vaccines

Vaccine Development Considerations

1. Human immune system response
2. Target population
3. Technology and manufacturing method

Vaccine Types

1. Live-Attenuated Vaccines: Weakened live virus (e.g., measles, rotavirus)
2. Inactivated Vaccines: Killed germs (e.g., hepatitis, polio)
3. Subunit/Recombinant/Polysaccharide/Conjugate Vaccines: Specific parts of germs (e.g., Human papillomavirus, whooping cough)
4. Toxoid Vaccines: Harmless toxins (e.g., diphtheria, tetanus)
5. DNA Vaccines: DNA strands for lifelong immunity (in development)
6. Recombinant Vector Vaccines: Platform-based vaccines for lifelong immunity (in development)
