Summary

This clinical trial is being done to learn more about how well a vaccine (Arexvy®) for respiratory syncytial virus, also known as RSV, works in people with weakened immune systems. The main questions it aims to answer are:

* Does 1 or 2 doses of Arexvy work better in people with weakened immune systems?
* What medical problems do participants have after receiving Arexvy?

Participants with weakened immune systems will:

* Receive 3 study vaccines over the course of 1 year
* Keep a diary of symptoms for 7 days after each vaccine
* Have 3 in-person follow up study visits for checkups and tests over the course of 1.5 years
* Have 6 phone follow up study visits over the course of 1.5 years
