Vaccination
Training immunity safely
Vaccination reduces disease burden, protects vulnerable populations, and supports herd immunity.
- herd immunity
- antibodies
- immunization
- public health
- prevention
Health Impact

How it works
Immune Response
See how barriers, immune cells, and antibodies coordinate to detect threats and clear infections.
Comparison
Mitosis vs Meiosis
Mitosis makes matching cells for growth and repair, while meiosis creates sex cells and introduces genetic variation.
Examples
Osmosis
Osmosis is water diffusion through a semipermeable membrane toward higher solute concentration.
