Post disaster (earthquake) in Pakistan, which of the following vaccines is recommended by WHO?
**Core Concept**
The World Health Organization (WHO) recommends specific vaccines in response to disasters, particularly those involving mass casualties and increased risk of infectious diseases. In the aftermath of an earthquake, the primary concern is the prevention of water-borne, food-borne, and vector-borne diseases.
**Why the Correct Answer is Right**
The correct answer is Oral Poliovirus Vaccine (OPV). In disaster situations, OPV is recommended by WHO due to its simplicity, ease of administration, and ability to provide herd immunity in areas with poor sanitation and hygiene. OPV also offers protection against poliomyelitis, a disease that can spread rapidly in crowded, unsanitary conditions.
**Why Each Wrong Option is Incorrect**
* **Option A:** Tetanus Toxoid Vaccine is recommended for wound management and prevention of tetanus, but it is not the primary vaccine recommended by WHO in the aftermath of a disaster.
* **Option B:** Inactivated Poliovirus Vaccine (IPV) is also used in polio eradication efforts, but it is not the preferred vaccine for mass administration in disaster situations due to its need for refrigeration.
* **Option C:** Diphtheria, Tetanus, and Pertussis (DTP) vaccine is essential for preventing diphtheria and pertussis, but it is not the specific vaccine recommended by WHO in the context of a disaster.
**Clinical Pearl / High-Yield Fact**
In disaster situations, the risk of water-borne and food-borne diseases increases due to contamination of water sources and sanitation systems. Vaccination programs, including OPV, are crucial in preventing the spread of infectious diseases in these settings.
**Correct Answer:** C. Oral Poliovirus Vaccine (OPV)
