**Core Concept:** Rabies is a viral infection caused by the Lyssavirus, transmitted through the bite of an infected animal. Human diploid cell culture vaccine (HDCV) is a preventive measure against rabies. Post-exposure prophylaxis involves a series of vaccinations and immune globulin administration.

**Why the Correct Answer is Right:** HDCV is administered as a series of intramuscular injections, starting on the day of exposure and continuing for 7 days, followed by a booster dose at 14 days post-exposure. This vaccination schedule ensures adequate production of neutralizing antibodies against the virus, providing protection against rabies.

**Why Each Wrong Option is Incorrect:**

A. This option does not mention the correct number of injections (7 days) and the booster dose at 14 days, which is crucial for effective post-exposure prophylaxis.
B. Although it mentions the proper vaccination schedule, it does not specify the correct number of injections (7 days) and the booster dose at 14 days.
C. This option is incorrect because it does not mention the correct number of injections (7 days) and the booster dose at 14 days.
D. This option is also incorrect because it does not mention the correct number of injections (7 days) and the booster dose at 14 days.

**Clinical Pearl:** Post-exposure prophylaxis for rabies is crucial to prevent the infection from progressing to the symptomatic stage. The HDCV vaccine and immune globulin administration must be administered according to the correct schedule to ensure effective protection against rabies.
