Summary
Brief summary
The purpose of this study is to evaluate the immunogenicity, safety, and reactogenicity of
the RSVPreF3 OA investigational vaccine in an immunocompromised (lung and renal transplant
recipients) population and assess whether a second dose of the vaccine increases the immune
response.
