The dengue vaccine should be available to the Brazilian population in the second half of this year. This is the prediction of the Brazilian Association of Vaccine Clinics. The National Health Surveillance Agency (Anvisa) approved the immunization device registration last Thursday (2).
Produced by Takeda Pharma, Qdenga is indicated for people ages 4 to 60 and is applied under the skin in a two-dose regimen, with a three-month interval between applications. “A vaccine that has shown very high efficacy, more than 80% in preventing dengue, 90% in preventing severe dengue, it is applied in two parts and very safe,” says Renato Kfouri, Deputy Chief Infectionist at the Brazilian Society of Immunization (SBIM). ).
The next step, according to the doctor, is to determine the most effective methods of vaccinating the population, as there are no doses available for everyone. “A large study is now needed so that we can determine which strategy will be best, with the best impact on the overall programme, since it will not be possible to vaccinate the entire population. Offering the vaccine to populations at higher risk, in those who get sick the most, Kfoury says seriousness, in areas where the disease is most intensely affected, seems to be the best strategy.”
The country already has a vaccine against the disease, which is transmitted by mosquitoes. Aedes aegyptiBut it was only available to those who had already contracted the virus. The Ministry of Health announced on Friday (3) that it will ask the National Committee for the Integration of Technologies into the Unified Health System (Conitec) to evaluate the Qdenga vaccine for inclusion in the National Immunization Program (PNI).
Until the vaccine is applied, the most effective form of prevention is fighting mosquitoes. Aedes aegypti. For this, there are precautions residents can take, such as checking that the water tank is well covered, putting sand in plant dishes, collecting and storing rubbish from the backyard, cleaning the gutters, covering swimming pools and all tanks. Water well.

However, the amount may be greater than the official statistics, as 109 more deaths are still under investigation across the country.
The volume recorded 1,450,270 cases of dengue last year, resulting in an incidence rate of 679.9 cases per 100,000 inhabitants — a jump of 162.5% compared to the same period in 2021. Brasilia and Goiânia stand out as the two cities with the highest number of diagnoses.
