NCT ID NCT06604767

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 1 study tests a new vaccine that aims to protect against three respiratory viruses at once: RSV, hMPV, and PIV3. The trial involves 390 adults aged 60 and older and will check if the vaccine is safe and helps the body produce antibodies. Different combinations and doses are being compared to find the best approach.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Combined vaccine targeting respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and parainfluenza virus type 3 (PIV3)
What this could lead to
If successful, this could lead to a single vaccine that protects older adults from three common respiratory viruses, potentially reducing severe illness and hospitalizations.
What could go wrong
This is an early Phase 1 trial with only 390 participants, so safety and immune response are still being tested. It may not work as hoped, and side effects like injection site reactions or fever are possible.
