Summary

This trial will look at how well a new vaccine works and how safe it is when given together with a COVID-19 vaccine, compared to when the vaccines are given separately in adults who are 50

Who is the study for?
This trial is for adults aged 50 and above who are interested in receiving vaccines against both RSV (Respiratory Syncytial Virus) and COVID-19. Participants should not have any health conditions that the study team thinks could interfere with the trial results or pose a risk.
What is being tested?
The study is testing how well an investigational RSV vaccine works when given at the same time as a new COVID-19 mRNA vaccine, compared to giving them separately. It's looking at immune response and safety of these vaccinations in older adults.
What are the potential side effects?
Possible side effects may include typical reactions to vaccines such as soreness at injection site, fatigue, headache, muscle pain, chills, fever, nausea. The exact side effects will be monitored closely throughout the trial.
