NCT ID NCT06611033
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tested a new vaccine called V118 Formulation C in 65 healthy adults to see if it is safe and well-tolerated. Participants received either the new vaccine, an existing pneumonia vaccine (Prevnar 20), or a placebo. Researchers monitored for side effects like injection-site reactions and general symptoms. The study is complete, but results are not yet publicly available.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
V118 Formulation C (pneumococcal vaccine candidate)
What this could lead to
If successful, this could lead to a new vaccine option to help prevent pneumococcal disease.
What could go wrong
This is an early Phase 1 trial with only 65 healthy adults, so it is too soon to know if the vaccine will be effective or safe for larger populations.
