Low-dose Administration of MERS DNA Vaccine Candidate Induces Potent Immunity and Protects From Virus Challenge in Preclinical Models
A synthetic DNA vaccine candidate for Middle East respiratory syndrome coronavirus MERS-CoV developed at The Wistar Institute induced potent immune responses and afforded protective efficacy in non-human primate models when given intradermally in abbreviated, low-dose immunization regimen. A similar vaccine candidate was previously shown to be safe and tolerable with a three-dose intramuscular injection regimen in a recently completed human phase 1 study and is currently in expanded studies of phase 1/2a trial.
