Study Summary

This trial is testing whether high-dose or standard-dose influenza vaccines are more effective in organ transplant recipients 1-11 months post-transplant.

Who is the study for?
Adults aged 18+ who are 1-11 months post solid organ transplant (kidney, heart, liver) can join this trial. They must be reachable for follow-ups and not pregnant or have had lung/intestine transplants, severe vaccine allergies, low platelets, Guillain-Barre syndrome, HIV, or recent immunoglobulin therapy.Check my eligibility
What is being tested?
The study is testing if a high-dose flu vaccine gives better immunity than the standard dose in new organ transplant recipients. Participants will get either two high doses, two standard doses or one high dose of the flu shot to see which works best.See study design
What are the potential side effects?
Flu vaccines may cause soreness at injection site, mild fever, fatigue or muscle aches. Rarely they could trigger allergic reactions. The higher dose might increase these side effects but is generally considered safe.
