Bulletproof vests, more accurately called ballistic vests or body armor, do not make wearers immune to injury from gunfire. While these vests are engineered to stop or slow penetrating projectiles, they cannot eliminate the physical trauma caused by the tremendous kinetic energy a bullet transfers on impact. Even when a round fails to penetrate the vest, the force is distributed across the body, often causing blunt force trauma such as broken ribs, internal organ damage, severe bruising, or in some cases fatal injury from the shock of impact alone.

Ballistic vests are also rated for specific threat levels based on standards set by organizations like the National Institute of Justice. A vest designed to stop handgun rounds may fail completely against rifle ammunition, which travels at much higher velocities and carries significantly more energy. No vest currently available offers protection against all calibers and projectile types, and armor-piercing rounds are specifically designed to defeat many forms of soft and even hard body armor.

Additionally, vests typically cover only the torso, leaving the head, neck, limbs, and extremities completely exposed. Many gunfire fatalities and injuries among people wearing body armor occur from shots to these unprotected areas. The common misconception that body armor renders someone "bulletproof" oversimplifies a complex field of materials science and ballistics. In reality, these garments reduce the likelihood of penetrating injury and can significantly improve survival odds, but they do not provide complete immunity from harm, injury, or death caused by firearms.
