Background: Lassa fever is a substantial health burden in west Africa. We evaluated the safety, tolerability, and immunogenicity of a recombinant, live-attenuated, measles-vectored Lassa fever vaccine candidate (MV-LASV).

Methods: This first-in-human phase 1 trial-consisting of an open-label dose-escalation stage and an observer-blinded, randomised, placebo-controlled treatment stage-was conducted at a single site at the University of Antwerp, Antwerp, Belgium, and involved healthy adults aged 18-55 years.

MV-LASV is an investigational measles Schwarz-based vaccine for the prevention of Lassa fever. A repeated-dose toxicity study in cynomolgus macaques was performed to assess the biodistribution and local and systemic toxicological effects. Monkeys received three immunizations of MV-LASV or saline intramuscularly with a 2-week interval.

Background: V591 (TMV-083) is a live recombinant measles vector-based vaccine candidate expressing a pre-fusion stabilized SARS-CoV-2 spike protein.

Methods: We performed a randomized, placebo-controlled Phase I trial with an unblinded dose escalation and a double-blind treatment phase at 2 sites in France and Belgium to evaluate the safety and immunogenicity of V591. Ninety healthy SARS-CoV-2 sero-negative adults (18-55 years of age) were randomized into 3 cohorts, each comprising 24 vaccinees and 6 placebo recipients.

Background: We report on the safety and immunogenicity of V591, a measles vector-based SARS-CoV-2 vaccine candidate.

Methods: In this multicentre, randomised, placebo-controlled, double-blind, phase 1/2 trial, healthy adults with no history of COVID-19 disease were assigned to intramuscular injection of V591 or placebo (4:1 ratio). In part 1, younger adults (18-55 years) received V591 median tissue culture infectious dose (TCID)-levels of 1×10 or 1×10 or placebo, 56 days apart.
