TLDR
This study in a nationwide mass vaccination setting suggests that the BNT162b2 mRNA vaccine is effective for a wide range of Covid-19–related outcomes, a finding consistent with that of the randomized trial.
Abstract
Background As mass vaccination campaigns against coronavirus disease 2019 (Covid-19) commence worldwide, vaccine effectiveness needs to be assessed for a range of outcomes across diverse p...

Double Negative Control Inference in Test-Negative Design Studies of Vaccine Effectiveness

TL;DR: A novel approach is presented to identify and estimate vaccine effectiveness in the target population by carefully leveraging a pair of negative control exposure and outcome variables to account for potential hidden bias in TND studies.

Ultrasound and shear-wave elastography patterns of COVID-19 mRNA vaccine-related axillary, supra and subclavicular lymphadenopathy.

TL;DR: In this paper, the ultrasound appearance of COVID-19 Pfizer-BioNTech vaccine-related lymph node abnormalities is illustrated, which can occur at different stations ipsilateral to the site of vaccination after either first or second vaccine dose and can represent a diagnostic dilemma when encountered in patients with underlying conditions.

Triple Jeopardy in Ageing: COVID-19, Co-morbidities and Inflamm-ageing.

TL;DR: For example, the authors found that the highest death rates are in the older and oldest age groups and in people with co-morbidities such as diabetes, heart disease and obesity.

Nonparametric Estimation from Incomplete Observations

TL;DR: In this article, the product-limit (PL) estimator was proposed to estimate the proportion of items in the population whose lifetimes would exceed t (in the absence of such losses), without making any assumption about the form of the function P(t).

Validation of a combined comorbidity index.

TL;DR: The estimated relative risk of death from an increase of one in the comorbidity score proved approximately equal to that from an additional decade of age.

Using Big Data to Emulate a Target Trial When a Randomized Trial Is Not Available

TL;DR: This work outlines a framework for comparative effectiveness research using big data that makes the target trial explicit and channels counterfactual theory for comparing the effects of sustained treatment strategies, organizes analytic approaches, provides a structured process for the criticism of observational studies, and helps avoid common methodologic pitfalls.
