Which of the following viral infections can be prevented through immunization?

Common cold
HIV
Hepatitis C
Hepatitis B

The correct answer is: Hepatitis B

Immunization can prevent the contraction of Hepatitis B, but not HIV, Colds, or Hepatitis C. The common cold is a common viral illness, but there is no vaccine for it. HIV is a retrovirus and has no vaccine available yet. Hepatitis C has no vaccine, but there are treatment options available. The only choice that has a vaccine available for prevention is Hepatitis B.
