What can be a consequence of under-vaccination in military personnel?

The choice indicating increased susceptibility to vaccine-preventable diseases effectively highlights a critical consequence of under-vaccination in military personnel. Vaccines are designed to prepare the immune system to fight specific pathogens, thereby reducing the risk of infections. When military personnel are under-vaccinated, they miss out on this protective benefit, leaving them more vulnerable to diseases that could otherwise be prevented, ultimately impacting their health, operational readiness, and overall effectiveness.

This situation not only affects individual soldiers but can also have broader implications for unit cohesion and mission capability, as illness can spread rapidly among troops and impact deployment readiness.
