Immunity as a Spectrum
- Immunity isn't a simple yes or no; it's a spectrum.
- Antibody tests reveal past infections but don't guarantee future immunity.
Innate Immunity: The First Wave
- The innate immune response is a fast, general defense against anything non-self.
- It's like an army's guerrilla fighters, attacking foreign or unusual cells.
Adaptive Immunity: The Second Wave
- Adaptive immunity is slower but more specific, like snipers targeting pathogens.
- It learns from past exposures, creating faster, stronger responses upon reinfection.
