**Question:** All the following are at-risk groups meriting Hepatitis B vaccination in low endemic areas except -

A. Health care workers (HCWs)
B. Patients with diabetes
C. Patients with chronic kidney disease (CKD)
D. Patients with HIV infection

**Correct Answer:** .

**Core Concept:** Hepatitis B vaccination is recommended for individuals at higher risk of acquiring the virus due to their occupation or medical conditions. In low endemic areas, the vaccination is particularly important for HCWs, patients with HIV infection, and patients with chronic kidney disease (CKD). However, diabetes is not considered a strong enough risk factor for Hepatitis B infection to warrant vaccination in this context.

**Why the Correct Answer is Right:** The correct answer is "B. Patients with diabetes" because diabetes is not a strong enough risk factor for Hepatitis B infection to warrant vaccination in low endemic areas. Although people with diabetes may have increased susceptibility to infections due to immune system impairment, the risk of contracting Hepatitis B is not significantly higher than the general population.

**Why Each Wrong Option is Incorrect:**

A. Health care workers (HCWs): HCWs are at high risk of contracting Hepatitis B due to occupational exposure to infected patients. Vaccination is crucial for these individuals to protect against Hepatitis B infection.

B. Patients with diabetes: As mentioned, while diabetes may increase susceptibility to infections, it does not significantly elevate the risk of Hepatitis B infection compared to the general population. Thus, vaccination is not deemed necessary for patients with diabetes in low endemic areas.

C. Patients with chronic kidney disease (CKD): Patients with CKD are at increased risk of Hepatitis B due to compromised immune systems and higher prevalence of Hepatitis B in certain populations with CKD. Vaccination is highly recommended for these individuals to prevent Hepatitis B infection.

D. Patients with HIV infection: Individuals with HIV infection are at high risk for Hepatitis B due to compromised immune systems, facilitating the progression of both infections. Vaccination is crucial for these individuals to protect against Hepatitis B infection.

**Clinical Pearl:** In low endemic areas, Hepatitis B vaccination is primarily recommended for HCWs, patients with HIV, and patients with CKD due to their higher risk of contracting the infection. While diabetes and CKD patients may benefit from vaccination, the risk is not as significant compared to the mentioned risk groups. Therefore, vaccination is not routinely advised for these patients unless they have specific risk factors or are exposed to high-risk situations.
