COVID-19 booster and flu vaccine timing for people with weak immune systems
Part of Bones, joints & muscles, Digestive system, Immune system & allergy, Infections, Lungs & breathing, Skin clinical trials.
This study tests the best timing for a COVID-19 booster and flu shot in people with weakened immune systems, such as organ transplant recipients, people living with HIV, or those with certain autoimmune conditions. It aims to help patients get better protection from both vaccines.
Summary written for real people, not researchers, by Clin2.

This study looks at how well a COVID-19 booster works in adults who need long-term medicines that lower immune response. It aims to see whether immunosuppressed people benefit from booster vaccination safely.
This trial tests a new type of COVID-19 booster vaccine that targets a protein to help your immune system. It's for people who already had a primary vaccine series and at least one mRNA booster, with the last booster at least 6 months ago.
This study looks at how your immune system responds to COVID-19 or the flu. It may help researchers understand these infections better, whether you are currently sick or healthy.
This study compares a high-dose flu vaccine to the standard dose in lung transplant recipients. It aims to see if a higher dose gives better protection against the flu.
This trial studies how well your immune system responds to a vaccine in people who are younger adults or, especially, older adults and those with frailty. Your participation may help researchers understand why vaccine responses can differ with age.
This study looks at how your lungs and lymph nodes respond to flu infection and the nasal flu vaccine. It will help researchers understand how to create better protection against the flu.
