Interconexin Electrica SAESP: ISA, One Health and the Government of Antioquia have worked together to administer over 10 million doses of COVID-19 vaccines in the department.
-On February 18, a year after the start of vaccination against COVID-19 in Antioquia, more than 67% of the population has already received all doses of the vaccine. The health brigades have reached the 125 municipalities of the department.
-Research conducted by the One Health Laboratory during this vaccination year showed that vaccination in adults has positive effects and that most hospitalizations were linked to other risk factors.
With more than 10 million doses administered throughout the department, coverage of more than 67% of the population in total number of doses and 17% of the population in boosters, Antioquia commemorates, on February 18, the first year of vaccination against COVID-19[FEMININE.
According to Lina María Bustamante Sánchez, Antioquia’s secretary of health, the vaccination was a process of hope. “The arrival of vaccines allowed us to evaluate, know and recognize what science can do for a common purpose. Today we can say that Antioquia has applied more than 10 million doses. We have 83% coverage for the first doses and 67% coverage for the total number of doses, however, the most important aspect is that the vaccine showed a decrease in the risk of complications and death We obtained the best results in the metropolitan area, East and Southwest In the most remote areas, such as Bajo Cauca and Urabá, which face problems of public order and displacement, strategies have been created to reach them. , we are counting on our partnership with the ISA and the Universidad Nacional, the mobile unit and the helicopter trips to develop Today, on the occasion of the celebration of the first year, we remember how important the science and human resources can t progress when they join forces, so we would also like to thank all the vaccinators in the department for their efforts and commitment.”
For their part, the mobile medical brigades, in partnership with the Universidad Nacional, Medellín Campus, the One Health Genomic Laboratory, ISA and the government of Antioquia have, since October 2021, enabled the administration of vaccines in the difficult territories of ‘access. , including indigenous and Afro-descendant populations. In this regard, María Adelaida Correa, director of corporate sustainability of ISA, points out that “the initial objective was to administer 26,000 doses in 16 municipalities, and we have already exceeded 42,000 doses in 47 municipalities. These figures give us motivate, and we hope that they will continue to grow through the arrival of this strategy in other departments of the country. Will and unity have been decisive in bringing a message of life and hope to the populations”.
Likewise, in this first year of vaccination, ISA ratifies its commitment to supporting communities through its Todos Somos Uno (We Are All One) humanitarian aid program which, through contributions of more than $5 million in Latin America, has supported multiple strategies to help mitigate the pandemic and foster economic recovery.
Preliminary results from the One Health genomic surveillance study
As part of the research and after the support offered to the National Institute of Health (INS) and the health authorities of Antioquia in the diagnosis of SARS-CoV-2, the One Health laboratory of UNAL Medellin supports, since February 2021, the genomic sequencing of the virus, i.e. determining its genetic composition. It also monitors the immune response to vaccines in a group of people.
This work involves determining the presence of antibodies and processing samples from infected people to identify which variants or lineages of the virus cause the disease. “This allows us to know the distribution and the real state of the viruses present in the regions and also the immune response to vaccines”, explains Karl Ciuoderis Aponte, scientific coordinator of the One Health Genomic Laboratory of UNAL Medellin.
Knowing the variants is important because they do not all behave the same way; some are more aggressive than others and some can even escape immunity generated by natural infection or vaccination. The information obtained suggests to what extent the territories are well or badly prepared to face future waves or to identify new variants.
In one year, the One Health laboratory at UNAL Medellin sequenced 2,577 samples mainly from Antioquia, representing almost 60% of the successful sequences provided to the Department, although it also processed samples from places such as Leticia (Amazonas), Barranquilla (Atlántico) or Villavicencio (Meta).
In addition, the duration of antibodies to vaccination was monitored. It has been found that most people have good levels of protection. People infected and hospitalized or having difficulties due to the severity of the disease had not been vaccinated, had been vaccinated more than six months ago or had received an incomplete number of doses; most of them were over 60, with comorbidities.
Therefore, vaccination has been shown to reduce the impact of the disease in the population, especially in high-risk populations.
Juan Pablo Hernández Ortiz, director of the One Health Laboratory, concludes that the institution is constantly on the lookout for the type of variant that the population is facing, “it is not only important because of the type of variant but also because we correlate it with naturalness and vaccine-induced immunity to have future vaccination strategies and prepare for what may come with the virus If Antioquia had not vaccinated people by administering more than 10 million doses , we will not say. Omicron, for example, is milder thanks to vaccination, not because the virus is less deadly; on the contrary, it is increasingly contagious and can cause patients with comorbidities to become infected. going to intensive care, but the vaccination stopped that.”
