What to expect at a Journal Club appointment

The Journal Club is a space to ask bold questions, challenge your assumptions, and sharpen your thinking! We welcome anyone with an interest in vaccines, health data, safety monitoring, real-world evidence, and methodology. A typical Journal Club appointment might go something like this: 

  • First, the presenter walks us through the scientific paper they’ve selected 
  • Topics span public health, pharmacoepidemiology, biostatistics, safety monitoring, and more! 
  • We listen actively, ask questions, and challenge our assumptions 
  • Don’t be shy! All questions are welcome, from clarifications to critical points 
  • Expect deep questions, open discussion, and occasional debates — all in a respectful space

Uncertainty in Science: Should We Say More, or Less?

Uncertainty in Science: Should We Say More, or Less?

A more scientifically literate public enables better engagement and understanding on complex socioscientific issues like COVID-19 or climate change. But how far do we need to go as researchers, communicators and educators? In a world full of misinformation, how do we communicate results effectively without overselling the impact? Do we need to explain the uncertain nature of science itself? How will this impact public trust?

Presenting at the Journal Club

The Journal Club is designed for researchers at all levels, especially early-career professionals working in public health, epidemiology, biostatistics, data sciences, and related fields. If that’s you, consider presenting at the Journal Club! You don't need to be an expert, and you don’t need to be a VAC4EU member. Here's what we ask of presenters:  

  • Select a scientific paper you find interesting  
  • Work with the Organising Committee to define the scope of the presentation  
  • Prepare a 20-30 minute presentation on the paper  
  • Start the discussion and see where it leads
