Cell-mediated immunity is essential to prevent reinfection by the

Brazilian researchers studied the case of identical twins in which only one sibling was reinfected and developed complications after a second exposure to the virus. Their analysis showed that the adaptive immune response can be different even between individuals with the same genome.
