Answer to Question 1

ANS: B
Viral vaccines contain live viruses that are weakened (attenuated). Viral vaccines do not contain active viruses, killed viruses, or toxins.

Answer to Question 2

ANS: C
Vaccines are biological preparations of weakened or dead pathogens that when administered stimulate production of antibodies or cellular immunity against the pathogen without causing disease. Vaccines are not fully active bacteria, nor are they synthetic or toxins.
