**Core Concept**
The post-disaster phase requires healthcare workers, including doctors, to receive vaccinations to protect them from potential outbreaks of infectious diseases. This is especially crucial in areas where medical infrastructure may be compromised, and the risk of disease transmission is higher.

**Why the Correct Answer is Right**
In the post-disaster phase, doctors are at a higher risk of contracting infectious diseases due to exposure to contaminated water, unsanitary conditions, and close contact with patients. The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) recommend that healthcare workers receive the following vaccinations:

* **Hepatitis A (HAV)**: This vaccine protects against hepatitis A, a highly contagious liver disease that can be spread through contaminated food and water, as well as through close contact with an infected person.
* **Hepatitis B (HBV)**: This vaccine protects against hepatitis B, a serious liver disease that can be spread through bodily fluids, including blood and semen.
* **Tetanus-diphtheria-acellular pertussis (Tdap)**: This vaccine protects against tetanus, diphtheria, and pertussis (whooping cough), three serious bacterial infections that can be spread through close contact or contaminated wounds.

**Clinical Pearl / High-Yield Fact**
In the post-disaster phase, healthcare workers should also be aware of the risks of zoonotic diseases, such as leptospirosis and hantavirus, which can be spread through contact with contaminated water or animals.

**Correct Answer: A.**
