Headline: Dengue Vaccine Shortages Heighten Concerns in Santa Fe, Argentina; Mosquito Sterilization Technique Trialed Amidst Increasing Cases
Article:
In an effort to combat the escalating dengue threat, the Municipality of Santa Fe has initiated a schedule of fumigation across plazas and bustling public spaces in the city. However, the provincial government’s worry has been exacerbated by the acute shortage of second doses of dengue vaccines in pharmacies. This deficiency could potentially compromise the immunization of those who have already started their vaccination schedules.
The recent influx of rain in Santa Fe has fostered optimal conditions for the breeding of the Aedes aegypti mosquito, essential to its life cycle. Yet, farmacias have been receiving insufficient vaccine doses for nearly three months’, with only a small fraction reaching them, according to the College of Pharmacists in Santa Fe. They express their ongoing struggle to meet the high demand, with an ambiguous assurance of a potential normalcy resuming in January.
While the Ministry of Health has refuted the risk of extended intervals between doses, public health experts caution that a prompt vaccination schedule is crucial. In Santa Fe city alone, 4,088 dengue cases have been reported between November 2023 and April 2024, with estimated total cases in the province reaching over 60,000.
To tackle this mosquito-borne threat, the Commission Nacional de Energia Atomica (CNEA) has been investigating a novel technique: Insect Sterilization. Recent trials involved the release of 25,000 fluorescently labeled, sterilized male mosquitoes in Ezeiza’s Barrio Uno. This Technique, which involves raising and irradiating male mosquitos to reduce fertility, holds promise in combating dengue.
As dengue cases continue to escalate, addressing vaccine shortages and exploring innovative mosquito control methods become essential in mitigating the health risks posed by this preventable disease.
