ABSTRACT

Para facilitar la introducción de la vacuna contra la COVID-19 el Ministerio de Salud Pblica y Asistencia Social (MSPAS) estableció el Comité Nacional de Coordinación para Vacunación contra COVID-19 (CNVCOVID) a través del Acuerdo Ministerial No 0262-2020, con la finalidad de desarrollar e implementar el plan estratégico nacional de vacunación contra la COVID-19. Este documento representa ese producto, en el cual se integran y describen los componentes esenciales para el despliegue de la vacunación contra la COVID-19 el cual se actualizará periódicamente, a medida que se obtenga información actualizada, científica, legal y técnico-operativa para fortalecer la estrategia de vacunación contra la COVID-19 en Guatemala

ABSTRACT

Abstract Since the emergence of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China at the end of 2019, when its characteristics were practically unknown, one aspect was evident: its high contagion rate. This high infection rate resulted in the spread of the virus in China, Europe, and, eventually, the rest of the world, including Mexico. At present, around 9 million people are infected, and around 470,000 have died worldwide. In this context, the need to generate protective immunity, and especially the generation of a vaccine that can protect the world population against infection in the shortest possible time, is a challenge that is being addressed in different countries using different strategies in multiple clinical trials. This opinion article will present the evidence of the induction of immune response in some of the viruses of the coronavirus family before COVID-19, such as SARS-CoV and MERS-CoV (Middle East respiratory syndrome coronavirus). The information collected about the induction of an immune response by SARS-CoV-2 will be presented, as well as a description of the vaccine candidates reported to date in the various ongoing clinical trials. Finally, an opinion based on the evidence presented will be issued on the potential success of developing vaccine prototypes.


Resumen Desde el surgimiento del nuevo coronavirus SARS-CoV-2 (coronavirus tipo 2 del síndrome respiratorio agudo severo) en China a finales del año 2019, cuando todavía era desconocido prácticamente en todos los aspectos, una característica era evidente: el alto índice de contagio entre la población. Esto resultó en la expansión del virus en China, Europa y, finalmente, en el resto del mundo, incluyendo México. Actualmente, alrededor de 9 millones de personas están infectadas, y han muerto cerca de 500,000 en todo el mundo. En este contexto, la necesidad de generar inmunidad protectora y, sobre todo, el desarrollo de una vacuna que pueda proteger a la población mundial contra la infección en el menor tiempo posible, es un reto que se está abordando en distintos países utilizando diversas estrategias en múltiples ensayos clínicos. En este artículo de opinión se presentan las evidencias de la inducción de respuesta inmunitaria con algunos de los virus de la familia de coronavirus previos al SARS-CoV-2, como el SARS-CoV (coronavirus del síndrome respiratorio agudo severo) y el MERS-CoV (síndrome respiratorio por coronavirus de Oriente Medio). Además, se presenta lo reportado hasta el momento acerca de la inducción de respuesta inmunitaria por el SARS-CoV-2, así como una descripción de los candidatos a vacunas informados hasta el momento en los distintos ensayos clínicos en curso. Finalmente se emite una opinión, basada en las evidencias presentadas, acerca del éxito potencial de los prototipos de vacunas en desarrollo.

ABSTRACT

El objetivo de este artículo es proporcionar una guía que sirva para la interpretación y seguimiento de los esfuerzos que se están desarrollando en todo el mundo con el objetivo de obtener una vacuna que pueda generar inmunidad contra el nuevo coronavirus SARS-CoV-2 de 2019, el agente causante de la enfermedad por coronavirus denominada COVID-19. Cinco meses después de haber sido detectada la enfermedad, ya hay 102 vacunas en distintos estadios de desarrollo, registradas por la Organización Mundial de la Salud (OMS), correspondientes a 8 plataformas vacunales con diferentes estrategias, y todos los días aparecen nuevas. Esto representará un enorme desafío de organismos internacionales, para la evaluación, comparación y selección de aquellas que cumplan con los criterios regulatorios indispensables de seguridad y eficacia y que, por otro lado, puedan ser producidas en cantidades suficientes para abastecer la demanda mundial.

The objective of this article is to provide a guide to help the interpretation and monitoring the efforts that are being carried out worldwide to obtain a vaccine that will be able to generate immunity against the new 2019 SARS-CoV-2 coronavirus, the viral agent causes the disease named COVID-19. Five months after the disease was detected, there are already 102 vaccines at different stages of development, registered by World Health Organization (WHO), corresponding to 8 vaccination platforms base on different strategies, and every day new ones appear. This will represent a huge challenge for international organizations, to evaluate, compare and selects those that will meet the essential regulatory criteria of safety and efficacy and that, would be able to be produced in enough quantities to supply the worldwide demand.

ABSTRACT

Abstract Since December 2019, an outbreak of Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in China and is now becoming a global Pandemic, with over 10.5 million cases worldwide. Angiotensin-converting enzyme-2 (ACE-2) has been considered the main receptor for the SARS-CoV-2 entry into human cells, and they are known to be present not only in lungs (therefore the common viral pneumonia) but also in nasopharyngeal mucosa, salivary cells and oral epithelial cells. Moreover, there seems to be recent evidence showing that the crevicular fluid on the periodontal pockets of patients presenting periodontitis could harbor SARS-CoV-2 and act as a potential reservoir for increased viral load in the oral cavity of COVID-positive patients. Additionally, sites with active periodontal disease might contribute for virus binding and tissue infection due to elevated expression of furin and cathepsin L proteases, which play a major role in enabling the SARS-CoV-2 to bind ACE-2 receptors and facilitating endosomal fusion in the host cells. Taken together this news and views article highlight possible virus reservoirs in COVID-positive patients, as well as increased risk for infection in patients with active periodontal disease, further proposing potential targets for antiviral intervention on SARS-CoV-2 infection.
