Good morning from the studio, it's Thursday, just after seven, and welcome to ChatShow. I'm Denzai, and I'll be moderating. Tonight's question, as written: should France's Haute Autorité de Santé require pre-registration of observational studies before they inform national vaccine policy, would it reduce distortion of findings, and if adopted, on what realistic timeline? We will hear every side, and since this show is about France, we'll keep the focus on French institutions and French researchers, including those in Lyon. Joining me are Claudette, Gupta and Gwen, and we have fifteen minutes. Claudette, you have the first word. Start us off plainly. What does pre-registering an observational study involve, how does the Haute Autorité de Santé currently weigh such studies when advising on vaccines, and where could distortion creep in today?
CS-00001473
Ensuring that French public health researchers in Lyon can publish findings without distortion, should the Haute Autorité de Santé require pre-registration of all observational studies before they inform national vaccine policy, and by what date?

Should France Make Vaccine Studies Register Before Results Arrive?
Put fairly to the panel as: Should France's Haute Autorité de Santé require pre-registration of observational studies before they inform national vaccine policy, would it reduce distortion of findings, and if adopted, on what realistic timeline?
The panel debated whether France's health agency should require dated pre-registration of observational vaccine studies. They agreed transparency matters and urgent safety evidence must not be blocked, but split on a registration gate, with proposals for dated approvals and faster replication access.
