NCT ID NCT06822907

First seen Jan 04, 2026 · Last updated May 15, 2026 · Updated 25 times

Summary

This study looks at whether giving the 20-valent pneumococcal vaccine (PCV-20) to adults while they have a fever works just as well as waiting until they are healthy. About 1052 adults at medium or high risk for pneumococcal disease will take part. The goal is to see if vaccinating during an acute febrile illness is safe and produces a strong immune response, which could help increase vaccination rates.
