          Abstract

          Resumen Nos propusimos discernir en qué medida las estrategias mediáticas adoptadas en torno a las vacunas contra la COVID-19, a lo largo de los primeros 15 meses desde el comienzo de su aplicación, pueden considerarse aportes legítimos y coherentes para comprender mejor su desempeño, y en qué grado las narrativas elaboradas pudieran responder a intereses económicos de las élites corporativas. Una vez recopilados los elementos más relevantes con que se configuran las narrativas predominantes desde el momento en que se concibieron las vacunas, se identificaron diversas anomalías que resultaron, en mayor o menor medida, invisibilizadas en el proceso de su aprobación y de los resultados de su aplicación. Las más significativas conciernen al manejo de las definiciones, los incumplimientos de compromisos y los conflictos de interés que comprometen la actuación de las empresas comercializadoras y los entes reguladores de las vacunas. Numerosos elementos relacionados con los intereses corporativos han gravitado en la elaboración del relato sobre las vacunas. Entre los que reclaman resignificación se hallan: su capacidad preventiva real de contagios, evoluciones graves y muertes, su eficacia ante nuevas variantes, la duración de la inmunidad que confieren, sus efectos adversos, el papel sinérgico de la inmunidad adquirida y los recursos empleados por las empresas para conseguir un predominio virtualmente monopólico en el mercado.

          Abstract We set out to discern to what extent the media strategies adopted around the vaccines against covid-19 during the first 15 months since the beginning of their application can be considered as a legitimate and coherent contributions to a better understanding about their performance and to what extent the elaborated discourses could respond to the economic interests of the corporations’ elites. Once the most relevant elements that have shaped the predominant narratives from the moment the vaccines were conceived were compiled, several anomalies were identified that were to a greater or lesser extent invisibilized in the process of their approval and the results of their application. The most significant of these concern the handling of definitions, non-compliance with commitments and conflicts of interest that compromise the actions of vaccine marketing companies and regulatory bodies. Many elements related to corporative interests have influenced the narrative concerning vaccines. Among those that require a resignification are: their real preventive capacity against contagions, serious diseases and deaths, their efficacy against new variants, the duration of the immunity they confer, their side effects, the synergic role of acquired immunity, and the resources used by the companies to achieve a virtually market monopolistic predominance.

          Estimating excess mortality due to the COVID-19 pandemic: a systematic analysis of COVID-19-related mortality, 2020–21

          (2022)
          Background Mortality statistics are fundamental to public health decision making. Mortality varies by time and location, and its measurement is affected by well known biases that have been exacerbated during the COVID-19 pandemic. This paper aims to estimate excess mortality from the COVID-19 pandemic in 191 countries and territories, and 252 subnational units for selected countries, from Jan 1, 2020, to Dec 31, 2021. Methods All-cause mortality reports were collected for 74 countries and territories and 266 subnational locations (including 31 locations in low-income and middle-income countries) that had reported either weekly or monthly deaths from all causes during the pandemic in 2020 and 2021, and for up to 11 year previously. In addition, we obtained excess mortality data for 12 states in India. Excess mortality over time was calculated as observed mortality, after excluding data from periods affected by late registration and anomalies such as heat waves, minus expected mortality. Six models were used to estimate expected mortality; final estimates of expected mortality were based on an ensemble of these models. Ensemble weights were based on root mean squared errors derived from an out-of-sample predictive validity test. As mortality records are incomplete worldwide, we built a statistical model that predicted the excess mortality rate for locations and periods where all-cause mortality data were not available. We used least absolute shrinkage and selection operator (LASSO) regression as a variable selection mechanism and selected 15 covariates, including both covariates pertaining to the COVID-19 pandemic, such as seroprevalence, and to background population health metrics, such as the Healthcare Access and Quality Index, with direction of effects on excess mortality concordant with a meta-analysis by the US Centers for Disease Control and Prevention. With the selected best model, we ran a prediction process using 100 draws for each covariate and 100 draws of estimated coefficients and residuals, estimated from the regressions run at the draw level using draw-level input data on both excess mortality and covariates. Mean values and 95% uncertainty intervals were then generated at national, regional, and global levels. Out-of-sample predictive validity testing was done on the basis of our final model specification. Findings Although reported COVID-19 deaths between Jan 1, 2020, and Dec 31, 2021, totalled 5·94 million worldwide, we estimate that 18·2 million (95% uncertainty interval 17·1–19·6) people died worldwide because of the COVID-19 pandemic (as measured by excess mortality) over that period. The global all-age rate of excess mortality due to the COVID-19 pandemic was 120·3 deaths (113·1–129·3) per 100 000 of the population, and excess mortality rate exceeded 300 deaths per 100 000 of the population in 21 countries. The number of excess deaths due to COVID-19 was largest in the regions of south Asia, north Africa and the Middle East, and eastern Europe. At the country level, the highest numbers of cumulative excess deaths due to COVID-19 were estimated in India (4·07 million [3·71–4·36]), the USA (1·13 million [1·08–1·18]), Russia (1·07 million [1·06–1·08]), Mexico (798 000 [741 000–867 000]), Brazil (792 000 [730 000–847 000]), Indonesia (736 000 [594 000–955 000]), and Pakistan (664 000 [498 000–847 000]). Among these countries, the excess mortality rate was highest in Russia (374·6 deaths [369·7–378·4] per 100 000) and Mexico (325·1 [301·6–353·3] per 100 000), and was similar in Brazil (186·9 [172·2–199·8] per 100 000) and the USA (179·3 [170·7–187·5] per 100 000). Interpretation The full impact of the pandemic has been much greater than what is indicated by reported deaths due to COVID-19 alone. Strengthening death registration systems around the world, long understood to be crucial to global public health strategy, is necessary for improved monitoring of this pandemic and future pandemics. In addition, further research is warranted to help distinguish the proportion of excess mortality that was directly caused by SARS-CoV-2 infection and the changes in causes of death as an indirect consequence of the pandemic.

              SARS-CoV-2 reinfections: Overview of efficacy and duration of natural and hybrid immunity

              Seroprevalence surveys suggest that more than a third and possibly more than half of the global population has been infected with SARS-CoV-2 by early 2022. As large numbers of people continue to be infected, the efficacy and duration of natural immunity in terms of protection against SARS-CoV-2 reinfections and severe disease is of crucial significance for the future. This narrative review provides an overview on epidemiological studies addressing this issue. National surveys covering 2020–2021 documented that a previous SARS-CoV-2 infection is associated with a significantly reduced risk of reinfections with efficacy lasting for at least one year and only relatively moderate waning immunity. Importantly, natural immunity showed roughly similar effect sizes regarding protection against reinfection across different SARS-CoV-2 variants, with the exception of the Omicron variant for which data are just emerging before final conclusions can be drawn. Risk of hospitalizations and deaths was also reduced in SARS-CoV-2 reinfections versus primary infections. Observational studies indicate that natural immunity may offer equal or greater protection against SARS-CoV-2 infections compared to individuals receiving two doses of an mRNA vaccine, but data are not fully consistent. The combination of a previous SARS-CoV-2 infection and a respective vaccination, termed hybrid immunity, seems to confer the greatest protection against SARS-CoV-2 infections, but several knowledge gaps remain regarding this issue. Natural immunity should be considered for public health policy regarding SARS-CoV-2.
