Final answer:
Healthcare workers are typically immunized against Hepatitis B, which also provides protection against Hepatitis D. There are vaccines available for Hepatitis A and Hepatitis B but not for Hepatitis C.
Step-by-step explanation:
If a patient states they have hepatitis and you have received immunizations prior to working, the type of hepatitis you are immunized against is most likely Hepatitis B. Since this is a common vaccine given to health-care workers to prevent transmission in health-care settings. For instance, since 1982, the Centers for Disease Control and Prevention (CDC) have recommended that health-care workers get vaccinated against HBV, and this has significantly reduced the infection rates among healthcare professionals. Vaccination against Hepatitis B also provides protection against Hepatitis D (HDV), because HDV can only propagate in the presence of HBV. It is important to note also that there is a vaccine available for Hepatitis A, which is protective against HEV as well. Unfortunately, there is no vaccine available against Hepatitis C at this time.
