Triple-Threat vaccine aims to shield seniors from three respiratory viruses
NCT ID NCT06984094
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests two new vaccines (SCB-1022 and SCB-1033) designed to protect against RSV, human metapneumovirus, and parainfluenza virus. About 612 healthy adults aged 60-85 will receive either a vaccine or a placebo. The main goal is to check safety and how well the vaccines trigger an immune response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- combination recombinant protein subunit vaccines (SCB-1022 and SCB-1033)
- What this could lead to
- If successful, these vaccines could protect older adults against three common respiratory viruses (RSV, hMPV, and PIV3) with a single shot.
- What could go wrong
- This is an early first-in-human study, so safety and immune response are still being tested. The vaccines may not work as hoped or could cause side effects.
