As the COVID-19 pandemic continues causing problems around the world, Chile is facing a new episode of increasing cases and deaths. However, at the same time, the country has succeeded in providing vaccines for an important part of its population over a short period. What are the factors behind this successful process? What are the challenges faced by the country today? This article explores potential explanations for the “Chilean paradigm”, regarding the COVID-19 vaccine rollout. Borrowing from implementation science frameworks, the analysis proposed an alternative explanation—based on multiple actors, approaches, and history—as opposed to one in which the outcome is due mainly to the government’s performance. The rapid and extensive coverage of vaccination can be explained by the role played by the government and the academia in securing vaccines through a pragmatic approach; the capacity built at local level, as well as the coordination between the health system and local authorities; and favorable vaccine culture, developed through the implementation of the National Immunization Program. Short and long-term elements (such as investment in infrastructure and relationships between stakeholders, and actions carried out during the pandemic), as well as contextual factors (such as the political and socioeconomic context), provide a more complex story to explain the observed outcomes. While other countries could try to follow the Chilean example, the article shows that short-term actions are necessary but might not be sufficient to achieve results. At a global level, the situation calls for rethinking how countries will face these global challenges, including issues such as international cooperation and global health governance.

The cold chain is a set of standards and procedures that ensure the correct storage and distribution of vaccines to health services from the national to the local level. Objective: To examine the scientific evidence on the cold chain for the conservation of COVID-19 vaccines. Methodology: An organized exploration of original articles was carried out by searching scientific articles published in databases such as: PubMed, SciELO, Web of Science, Google Scholar, also documents from health organizations and authorities; using the following keywords (cold chain, vaccine conservation, knowledge, nursing personnel, Covid-19); with a maximum age of 5 years and without limitation of languages. Results: According to the information obtained, the recommendations for conservation in transport are expressed by the manufacturer refrigerated (2◦C to 8◦C) storage at the place of administration before diluting or piercing the vial. Storage after diluting or piercing the vial: should be at temperature of 2◦C to 25◦C: stable 6 hours. Conclusion: Considering the cold chain as a set of norms and procedures that ensure the correct storage and distribution of vaccines, these norms should be followed to keep them in good condition at the time of administration to the patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
