🚨 Misrepresentation in Scientific Research: The Case of Uspecific Vaccine Effects 🚨
A recent investigative article exposes troubling patterns in the research of Peter Aaby and Christine Stabell Benn on the so-called "unspecific effects" of vaccines.

Le vaccin proposé contre la grippe pour les enfants en Angleterre est un spray nasal (et non une injection contrairement à la France), il est gratuit, et proposé proactivement à tous les enfants par courrier ou SMS aux parents, ce qui explique le meilleur taux de couverture.

Do you work on clinical trials?

Curious to hear from people: it is common in research to give an Amazon voucher to participants (e.g. Delphi surveys). Do you see an ethical issue with it (because, well, it's Amazon) and if so, what could be a more ethical alternative (that can be used from any country)?

Simulating Data From Marginal Structural Models for a Survival Time Outcome Marginal structural models (MSMs) are often used to estimate causal effects of treatments on survival time outcomes from observational data when time-dependent confounding may be present. They can be...

New paper from Shaun Seaman and me on how to simulate data from marginal structural models (MSMs) for survival outcomes, including Cox MSMs. This can be useful in simulation studies evaluating causal inference methods that use MSMs. R code provided. onlinelibrary.wiley.com/doi/10.1002/...

True. The lack of diversity among panel members contributes to the issue as well.

In the UK, things are improving, but somehow France still loves impact factor, H-index and SIGAPS points, despite DORA being now widely endorsed...
