B. take immunosuppressants to reduce the immune systems attack what it thinks is a “foreign” invader

C. take antibiotics to prevent the immune system from attacking

D. give the patient more antigens

C. white blood cells and enzymes

D. red blood cells and antibodies

Describe a vaccine.

B. live fungus

C. weaken or live virus

D. weakened or dead pathogen

Which response usually occurs after an individual receives a vaccination for the influenza virus?

A. hormones in the blood stop reproduction of the virus

B. pathogens from the vaccine deactivate the virus

D. changes pathogenic bacteria into harmless bacteria

Describe how a vaccine protects the body from disease.
