We need more "unfunded" research, not less. Or rather, we need more "core" funding and much less project based funding. Then universities can *invest* in core research infrastructure (including people), reduce precarity, and focus on growing and retaining talent.

The anti-vaccine crowd say they just want to “see the evidence” in the form of placebo-controlled randomized trials. But we've done these trials. And we know our vaccines work. Which is precisely why we can't use placebo to test better vaccines. Read more: epiellie.substack.com/p/first-do-n...
New vaccines get placebo-controlled trials. Improved vaccines shouldn't.

In 2023, Spain started recommending systematic nirsevimab administration to all infants born or entering their first #respiratory #virus season Núñez et al. look at effectiveness of nirsevimab in preventing hospital admission due to #RSV infection in the 2023/24 season 🗞️ bit.ly/EUS305RSV 🧪😷🩺 🛟
Image showing the Key public health message for this paper.

What did you want to address in this study and why?

The administration of a long-acting monoclonal antibody, such as nirsevimab, in a population-wide immunisation campaign has no precedent in public health practice. Assessing the effectiveness of this preventive intervention against severe RSV infection in children in their first respiratory virus season is of utmost importance to inform future recommendations.

What have we learnt from this study?

The risk of hospitalisation for an RSV infection was reduced by around 80% in children under 6 months who received nirsevimab immunisation. Effectiveness was similar for intensive care admission and need of mechanical ventilation, as well as for different RSV subgroups, while effectiveness was slightly lower for children born pre-term, with low birthweight, or from multiple pregnancy.

What are the implications of your findings for public health?

Our results support nirsevimab administration to all children born during or entering their first respiratory virus season and show that the entire newborn population greatly benefited from this intervention, including children with comorbidities or low birthweight and those born pre-term or from multiple pregnancy.
