1. Passive Immunity

1.1. Premade antibodies from animal or human

1.2. Immediate but short-acting protection

1.2.1. Immunoglobulin therapies

1.2.1.1. Measles (rubella)

2.1. Active: Body WILL produce antibodies and memory cells!

2.1.1. Active: Long term protection!

2.2. Passive: Body WILL NOT produce antibodies and memory cells!

2.2.1. Passive: Short term protection!

3. Naturally Acquired Active Immunity

3.1. Invading viruses and bacteria act as antigen

3.1.1. Body creates an immune response/antibodies to antigen

3.1.1.1. Ex. Measles immunity after infection

4. Artificially Acquired Active Immunity

4.1. Killed or weakened viruses act as the antigen

4.1.1. After being administered to client, memory B cells "remember" antigen in the future when detected

4.1.1.1. Think immunizations!

4.1.1.1.1. Influenza

4.1.1.1.2. COVID

4.1.1.1.3. Pneumonia

4.1.1.1.4. TDAP
