Will COVID-19 vaccines be safe? Will all the COVID-19 candidate vaccines be successful? What are the different phases a vaccine must go through to be approved? This document provides responses to the most frequently asked questions about candidate vaccines and access to COVID-19 vaccination.
This action plan for the Kingdom Saudi Arabia to combat antimicrobial resistance has been formulated in the line of the WHO five objectives. It addresses the need for effective “one health” approach involving coordination among numerous national sectors and actors, including human and veterinary... medicine, agriculture, finance, environment, and well-informed consumers. Therefore, a large committee of all stakeholders was formed with five technical subcommittees were established to addresses every aspect
to contain antimicrobial resistance in the country.

Interim Guidance, published 11 January 2021.
The cold chain is necessary to prevent damage to vaccines caused by heat exposure. However, improper use of cold chain equipment may cause damage to freeze-sensitive vaccines (i.e. those vaccines containing alum adjuvant or oil-emulsion adjuvant). Studie...s conducted in several countries with hot and cold climates show frequent occurrences of sub-zero temperatures in the cold chain. The most common cause of exposure to freezing temperature is the failure to correctly condition ice packs prior to transport. Vaccines that are inadvertently frozen lose potency, increase wastage rates and increase the risk of adverse events following immunization (AEFI). Vaccine carriers protect vaccine potency during immunization sessions and transport to outreach sites. This guidance document is intended to help inform which type of vaccine carrier to select based on local context, to maintain vaccine quality, especially at service delivery points.

La Organización Panamericana de la Salud publica la tercera versión de la lista de dispositivos médicos prioritarios (LDMP) para el primer nivel de atención, elaborada de acuerdo con la realidad epidemiológica de los países de la Región de las Américas y adaptada al contexto de la pandemia d...e COVID-19. Con vistas a que la LDMP pueda adaptarse a las diferentes formas de organización de los sistemas de salud de la Región, esta tercera versión incluye una lista principal (223 dispositivos médicos), un módulo de diagnóstico por imágenes (30 dispositivos médicos), un módulo de laboratorio (29 dispositivos médicos) y un módulo de odontología (69 dispositivos médicos). Los usuarios deben seleccionar solo los módulos que contienen las prácticas que se planifica ofrecer en un centro de atención de primer nivel y analizar las listas correspondientes.

This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

La capacidad de respuesta de un hospital puede ser superada por la llegada masiva de pacientes que soliciten atención médica como consecuencia de una situación de emergencia. Ante este escenario, se debe considerar si el establecimiento de salud está organizado para garantizar la gestión integr...al de la respuesta hospitalaria, el funcionamiento de los mecanismos de coordinación, el manejo integral de la información, las capacidades logísticas para facilitar la respuesta, y los recursos necesarios para su ejecución, así como para una respuesta integral a los pacientes, precautelando la salud y bienestar de los trabajadores de salud.
