The effectiveness of Sanofi Pasteur´s dengue vaccine (Dengvaxia®) according to age will be assessed in 5 municipalities of Paraná State - Maringá, Foz de Iguaçu, Londrina, Sarandi and Paranaguá. The municipalities were chosen because they are of medium size and have a history of dengue. The first 4 present a historical series of occurrence of dengue since the 1990s, while in Paranaguá the history of the disease is more recent. Any health service located in each of the five municipalities may report a suspected dengue case. In all five municipalities, there is a large public emergency service, the UPA, which is responsible for reporting the majority of suspected dengue cases. In Londrina and Maringá, the private health sector also provides emergency care.
