3

What are two sources of passive immunization?

- NATURAL: mother-to-child via placenta (immunity in first few months to 1 year of life)
- ARTIFICIAL; necessary in
--> patients who cant mount a response
--> individuals exposed to deadly toxins (snake bite, etc)
--> rapidly-progressing infections (rabies)

- Artificial (vaccination)

4
