NCT ID NCT07428759

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

Summary

This early-stage trial tests a new pneumococcal vaccine called PnMAPS30plus in 121 healthy adults aged 50 to 64. Participants receive a single shot of either the new vaccine or an approved one (PCV20) and are monitored for about six months. The goal is to check safety and whether the vaccine triggers a strong 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

PnMAPS30plus (investigational pneumococcal vaccine)

What this could lead to

If successful, this could lead to a new vaccine option to protect against pneumococcal disease in older adults.

What could go wrong

This is an early Phase 1 trial with only 121 participants, so it's too soon to know if the vaccine works or is safe. The study focuses on safety and immune response, not on preventing pneumonia.
