60 and older, any sex, with Respiratory Syncytial Virus Infection or Metapneumovirus Infection. Patients with the condition only — healthy volunteers not accepted.

Sponsor's own description

The purpose of this phase 1 study is to evaluate whether the vaccine is safe and can help the body to develop germ fighting agents called "antibodies" (immunogenicity) against the respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and parainfluenza virus type 3 (PIV3). The study will use different doses of PIV3 only and different combinations of RSV/hMPV/PIV3 or RSV/hMPV or only RSV vaccine in adults aged 60 years and older.
