Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

People who are infected with human metapneumovirus (HMPV) may develop upper and lower respiratory illnesses. Children are particularly sensitive to HMPV infection. This study will evaluate the safety and immune response of an HMPV vaccine in healthy adults, HMPV-seropositive children, and HMPV-seronegative infants and children.

Investigators

The overall officials registered on this study. Names that resolve to a findmyKOL profile link to it; the rest are shown as registered.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

2 registered facilities, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

United States
  • Center for Immunization Research, Johns Hopkins Bloomberg School of Public Health

    Baltimore, Maryland, United States

  • Seattle Children'S Hospital

    Seattle, Washington, United States

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
