In 2023, Brazil recorded more than 1.6 million cases of the disease, more than a fifth of all reported cases in the world, and 1,094 deaths, a historic record.
The Brazilian government has released the list of cities that will receive the dengue vaccine. In all, about 500 cities in 16 states are listed for vaccination, which should initially prioritize children and teens ages 10 to 14 because they are among the populations with the highest number of hospitalizations for the disease.
The country expects to receive up to 6.2 million doses of the Japanese dengue vaccine in 2024. However, since it is a vaccination that requires two doses of the vaccine, this amount covers only 3.1 million people and is insufficient to cope with the current explosion of cases. .
The Ministry explained in a statement regarding public vaccination against dengue fever, which will begin in the country next February, that during the rainy season and high temperatures, and in light of the warning issued by the World Health Organization about the increase in arboviruses due to climate and change resulting from the El Niño weather phenomenon, a series will be coordinated. Preparatory activities for the dengue season in 2024.
El Niño occurs on average every two to seven years and is a natural climate phenomenon associated with rising surface temperatures in the central and eastern tropical Pacific Ocean, but it has impacts around the world.
The effects of this phenomenon are reinforced by rising temperatures in the Americas, which ultimately facilitates the reproduction of the Aedes aegypti mosquito, which transmits dengue fever.
