Drive-Through Mass Vaccination Center Operations in a Rural, Medically Underserved Area Using Military Civilian Partnership During the COVID-19 Pandemic.

During the coronavirus disease (COVID-19) pandemic, mass vaccination centers became an essential element of the public health response. This drive-through mass vaccination operation was conducted in a rural, medically underserved area of the United States, employing a civilian-military partnership. Operations were conducted without traditional electronic medical record systems or Internet at the point of vaccination. Nevertheless, the mass vaccination center (MVC) achieved throughput of 500 vaccinations per hour (7200 vaccinations in 2 days), which is comparable with the performance of other models in more ideal conditions. Here, the study describes the minimum necessary resources and operational practicalities in detail required to implement a successful mass vaccination event. This has significant implications for the generalizability of our model to other rural, underserved, and international settings.

Effective peer education in HIV: defining factors that maximise success.

UNLABELLED: Background Peer education is considered an effective health promotion and education strategy, particularly to populations traditionally resistant to conventional forms of health information dissemination. This has made it very applicable to HIV education and prevention, where those who are affected or at risk are often amongst the most vulnerable in society. However, there still remains uncertainty as to the reasons for its effectiveness, what constitutes an effective methodology and why a consistent methodology can often result in widely variable outcomes. METHOD: Between 2008 and 2010, three separate reviews of peer education were undertaken across more than 30 countries in three distinct geographical regions across the globe. The reviews sought to identify determinants of the strengths and weaknesses inherent in approaches to peer education, particularly targeting young people and the most at-risk populations. RESULTS: By assessing the implementation of peer education programs across a variety of social environments, it was possible to develop a contextual understanding for peer education's effectiveness and provide a picture of the social, cultural, political, legal and geographic enablers and disablers to effective peer education. Several factors were significant contributors to program success, not as strategies of methodology, but as elements of the social, cultural, political and organisational context in which peer education was situated. CONCLUSION: Contextual elements create environments supportive of peer education. Consequently, adherence to a methodology or strategy without proper regard to its situational context rarely contributes to effective peer education.

Continuous ice-core chemical analyses using inductively coupled plasma mass spectrometry.

Impurities trapped in ice sheets and glaciers have the potential to provide detailed, high temporal resolution proxy information on paleo-environments, atmospheric circulation, and environmental pollution through the use of chemical, isotopic, and elemental tracers. We present a novel approach to ice-core chemical analyses in which an ice-core melter is coupled directly with both an inductively coupled plasma mass spectrometer and a traditional continuous flow analysis system. We demonstrate this new approach using replicated measurements of ice-core samples from Summit, Greenland. With this method, it is possible to readily obtain continuous, exactly coregistered concentration records for a large number of elements and chemical species at ppb and ppt levels and at unprecedented depth resolution. Such very-high depth resolution, multiparameter measurements will significantly expand the use of ice-core records for environmental proxies.
