Rabies vaccine for pre exposure prophylaxis is given at?
**Core Concept**
The question pertains to the administration of rabies vaccine as pre-exposure prophylaxis (PrEP) to individuals who are at high risk of exposure to the rabies virus, such as laboratory workers, veterinarians, and travelers to areas with high incidence of rabies.
**Why the Correct Answer is Right**
Rabies vaccine is administered to provide immunity against the rabies virus before exposure. The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) recommend a pre-exposure regimen consisting of 2 doses of rabies vaccine, given on days 0 and 7. This schedule is based on the fact that the immune response to the vaccine takes about a week to develop, and the second dose is given to provide a booster effect and ensure optimal immunity.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the recommended schedule for pre-exposure rabies vaccination is not a single dose.
**Option B:** This option is incorrect because the recommended interval between doses for pre-exposure rabies vaccination is 7 days, not 14 days.
**Option C:** This option is incorrect because the recommended number of doses for pre-exposure rabies vaccination is 2, not 3.
**Option D:** This option is incorrect because the recommended interval between doses for pre-exposure rabies vaccination is 7 days, not 30 days.
**Clinical Pearl / High-Yield Fact**
It's essential to note that the pre-exposure rabies vaccination schedule may need to be adjusted in individuals with immunocompromising conditions or those taking immunosuppressive medications.
**Correct Answer:** C. 2 doses 2 weeks apart
