1. New Technologies in Vaccines

2. Pandemic When an infectious disease breaks out worldwide
Smallpox, Bubonic plague, “Spanish Flu”
Influenza pandemics high risk
can spread among animals as well as people
Many rapidly changing strains
Key weapons is vaccination

3. The goal of Vaccines To prevent disease
NC requires vaccination against 10 different diseases by the time children start school
CDC recommends vaccination against 5 more
Lowering disease in a population protects those who are too young, allergic to vaccine ingredients or those who have weakened immune system.

4. Our immune system protects us from disease by an array of defenses
Our immune system protects us from disease by an array of defenses. The purpose of a vaccination: to jump-start a specific immune response by introducing the person to enough of a disease to cause an immune response but not enough to cause illness. These foreign proteins are called antigens. Different types of white blood cells work to eliminate the antigens. Macrophages T cells B cells
How Vaccinations Work
Don’t forget that disease!
Once the immune system has learned to make antibodies against a particular disease it makes both T and B memory cells. The memory cells are ready to attack if that specific disease invades again.

5. Types of Vaccines
Live but weakened disease agents Inactivated or killed disease agents Subunit vaccines Toxoid vaccines Conjugate vaccines DNA Vaccines (experimental stage) Recombinant vector vaccines (experimental stage)
