1. Immunology
Immune Response

2. 1st Exposure = Primary Response
2nd Exposure = Secondary Response

3. Primary Response
Latent Period = Time to find antigens and react
1 to 2 weeks depending on B cell response time

6. Some cells set aside for future = Memory Cells

7. Secondary Response
1/2 time to respond
