Types of Immunity

1. Naturally Acquired Active Immunity

1.1. Invading viruses and bacteria act as antigen

1.1.1. Body creates an immune response/antibodies to antigen

1.1.1.1. Ex. Measles immunity after infection

2. Artificially Acquired Active Immunity

2.1. Killed or weakened viruses act as the antigen

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

2.1.1.1. Think immunizations!

2.1.1.1.1. Influenza

2.1.1.1.2. COVID

2.1.1.1.3. Pneumonia

2.1.1.1.4. TDAP

3. Passive Immunity

3.1. Premade antibodies from animal or human

3.2. Immediate but short-acting protection

3.2.1. Immunoglobulin therapies

3.2.1.1. Measles (rubella)

3.2.1.2. Pertussis (whooping cough)

3.2.1.3. Hepatitis B

3.2.1.4. Chicken Pox (varicella)

3.2.1.5. Tetanus

3.2.2. Newborn babies

3.2.2.1. Antibodies cross the placenta

3.2.2.2. Breastmilk/colostrum

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

4.1.1. Active: Long term protection!

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

4.2.1. Passive: Short term protection!
