This clinical trial is focused on studying a disease called Respiratory Syncytial Virus (RSV) infections, which can cause respiratory illnesses, especially in older adults. The study will use a vaccine known as Arexvy, which is designed to help the body build protection against RSV. This vaccine is given as an injection and contains a special protein from the virus, combined with an ingredient that helps boost the body’s immune response.
The purpose of the study is to evaluate how well the vaccine works and how safe it is for people aged 60 and above. Participants in the study will receive the vaccine at different times to see how their immune systems respond. Some participants will receive a single dose of the vaccine, while others will receive a revaccination dose before the RSV season. The study will monitor the immune response by measuring the levels of protective substances in the blood before and after vaccination.
Throughout the study, participants will be observed for any side effects or health changes. The study will also track any serious health events that occur after vaccination. This research aims to understand the best vaccination schedule to protect older adults from RSV infections effectively.
