Summary
This first-in-human clinical trial, was a dose escalation multi-center trial designed to assess the safety, tolerability, and immunogenicity of the vaccine component, BNT165b1, a ribonucleic acid (RNA)-lipid nanoparticle (LNP) encoding for part of the Plasmodium falciparum circumsporozoite protein (PfCSP). BNT165b1 was evaluated at three dose levels (DLs) to select a safe and tolerable dose in a 3-dose schedule.
