Resistance to HIV refers to individuals who cannot be infected even when exposed to the virus. This suggests that they may have a unique genetic makeup or immune system response that prevents the virus from entering their cells and causing an infection. Being immunized or having a strong immune system may provide some protection, but it would not necessarily result in complete resistance to the virus. The behavior of an individual does not affect their susceptibility to the virus, as even individuals who engage in low-risk behavior can still become infected if they are exposed to the virus.
