#' Dengue Vaccine
#'
#' Results from an early trial for a vaccine for Dengue fever.
#' Patients were randomized into two groups. Patients in the
#' treatment group received the vaccine, and those in the control
#' group received a placebo. After 6 months, each patient was
#' injected with a weaker virus of Dengue. Researchers subsequently
#' took blood measurements, inspecting if any virus was present,
#' and also reported if any rash developed.
