This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether the time of day you receive your flu vaccine affects how well your body responds to it. Researchers will give some participants the VAXIGRIPTETRA flu vaccine in the morning and others in the evening, then measure how well each group's immune system responds. This study focuses on people with chronic kidney disease, whose immune systems don't always respond as strongly to vaccines.
People with chronic kidney disease are at higher risk from flu but often don't develop strong protection from the vaccine. Recent research suggests that the time of day you receive a vaccine may affect how well it works, so researchers want to see if giving this medication in the morning instead of the evening could help more patients stay protected.

You will receive a single flu vaccine injection at either a morning appointment (between 7 and 11 a.m.) or an evening appointment (between 5 and 9 p.m.), depending on which group you're randomly assigned to. After the injection, researchers will check your blood to measure how well your immune system responded to the vaccine. The study involves one vaccination visit, and you'll likely have follow-up blood tests to track your immune response over time.
