Could a Lower-Dose polio vaccine help eradicate the disease?

NCT ID NCT06413121

First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time

Summary

This study tests a hexavalent vaccine that protects against six diseases, including polio, but uses a lower dose of the inactivated polio vaccine (IPV). The goal is to see if this reduced-dose version works as well as the standard full-dose vaccine in infants. Around 1,500 healthy infants aged 6-8 weeks will receive three primary doses and a booster. If effective, this approach could lower costs and increase vaccine supply, aiding global polio eradication.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Hexavalent (DTwP-HepB-IPV-Hib) vaccine with reduced dose IPV
What this could lead to
If successful, this vaccine could help make polio protection more affordable and available worldwide, supporting global eradication efforts.
What could go wrong
This is a phase 3 trial, but reducing the IPV dose might still result in lower immune responses for some infants. Safety and effectiveness need confirmation.
