In Exercise identify which of these designs is most appropriate for the given experiment: completely randomized design, randomized block design, or matched pairs design.

HIV Vaccine The HIV Trials Network is conducting a study to test the effectiveness of two different experimental HIV vaccines. Subjects will consist of 80 pairs of twins.
