Days ago, Infobae reported on a series of strategies of the Ministry of Health against dengue and how the national portfolio proposes get ahead of the eventual next outbreak 2024-2025.

Minister Mario Russo structured the plan against dengue supported by three fundamental pillars: on the one hand, the experts from the National Immunization Commission (CoNaIn) and its scientific recommendations for the use of the available vaccine and epidemiological surveillance, among others; On the other hand, tailored and specific work in each territory that must be planned by the country’s jurisdictions, which will receive transfers from the Nation – money items, for example through the SUMAR program – based on the achievement of goals.

Russo also sat at the table – and in a privileged place – at the Pan American Health Organization (PAHO) in its dual role as a trustworthy and observatory body in matters of local-regional-global public health and also to guarantee access to vaccines through the revolving fund.

The vaccine will not be part of the National Vaccination Calendar for now.

In dialogue with Infobae, Minister Russo explained: “We will start progressively and in stages – approximately starting August 2024in the endemic areas of the NEA and NOA, with vaccination against dengue for young people between 15 and 19 years old, that the State will provide. It will be a joint task with each of the jurisdictions and the consensus that we achieve with the experts.

As of the last meeting that resulted in a minute of the National Immunization Commission (CoNaIn) that occurred on April 11, 2024, the national Health portfolio resolved for the entire country:

  • Against the available dengue vaccine – TAK-003, also known as Qdenga® – produced by the Japanese laboratory Takeda – a focused strategy. At the current moment, according to the epidemiological situation, It is not a vaccine to be incorporated into the National Calendar for all jurisdictions in the country.
  • The target population to apply the immunizations will be people between 15 and 39 years old in prioritized departments according to epidemiological situation. That is, endemic areas, we will begin in the Northeast (NEA) and Northwest (NOT).
  • HE It will begin in stages with the population from 15 to 19 years old and progress will be made dynamic, progressive and staggered according to availability of vaccines and strategies already implemented by jurisdictions.
