Clinicaltrials.gov identifier NCT03942406

Recruitment Status Completed

First Posted May 8, 2019

Study Description

Brief summary:

This study evaluates the safety and immunogenicity of the BPZE1 live attenuated pertussis vaccine, intended to prevent nasopharyngeal colonization and pertussis disease, and compares a single (prime) BPZE1 dose or 2-dose (prime + boost) to a single (prime) Boostrix or BPZE1 prime + Boostrix boost. This is a multi-center, randomized, placebo-controlled, and observer blinded trial in healthy adults with a 6 month safety follow-up after the last vaccination.
