Vaccines (Two column notes) 1. Different viruses spread different ways: *Contact with body fluids *Moisture drops from sneezes & coughs *Insect bites *Contaminated objects (Is he a fake?)

Look at the data in the following table. Anyone can get infected. Baby kissers, if infected, could also spread some viruses. Look at the data in the following table. Do more people just happen to catch diseases or do more people do behaviors to catch diseases? (Table shows new cases per year)

.

Vaccines Two column 2. There are no cures or medicines that kill viruses. Only white blood cells and the antibodies they produce can kill viruses.

3. Vaccines work by activating the body’s natural defense ahead of time. (Hope this organism was vaccinated)

4. A virus’s antigenic site must fit a cell’s receptor for an attachment and infection to occur. See textbook page 319.

5. Vaccines contain the proteins from a virus’s antigenic sites.

6. Proteins from a virus’s antigenic sites are called antigens.

7. The body’s immune system learns to identify virus antigens and makes antibodies that can attach to them.

8. Viruses are destroyed when antibodies attach to them.

9. Active viruses enter a host cell and immediately force it to produce more viruses.

10. Hidden viruses enter a cell and hide in the cell’s DNA before becoming active at a later time.

11. Antibiotics don’t stop viral infections or virus production, so they are not a treatment for viral illnesses. Antibodies made by white blood cells stop viruses. Other WBCs destroy viruses.

12. Some viral infections can be prevented with vaccines.
