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.
