Question

vaccines can prevent which? a. all bloodborne illnesses. b. all fatal illnesses. c. most, but not all, bloodborne illnesses. d. all minor illnesses.

Explanation:

Vaccines work by stimulating the immune - system to recognize and fight specific pathogens. They cannot prevent all bloodborne illnesses as some are caused by factors that vaccines cannot target (e.g., certain toxins in the blood). They also cannot prevent all fatal or minor illnesses. There are many types of fatal and minor illnesses that are not related to vaccine - preventable pathogens.

Answer:

C. Most, but not all, bloodborne illnesses.
