mRNA-1975 / Moderna - LARVOL DELTA

Monovalent and multivalent OspA mRNA-LNP vaccines elicit functional antibodies and protect against Borrelia burgdorferi in mice. (PubMed, NPJ Vaccines) - P1/2 | "Finally, mice vaccinated two or three times with different dose levels of OspA ST1 mRNA-LNP or with the heptavalent mRNA vaccine were protected against B. burgdorferi infection in a tick-mediated challenge model. The monovalent and the heptavalent OspA mRNA vaccines (mRNA-1982 and mRNA-1975, respectively) are currently undergoing testing in a Phase 1 clinical trial (NCT05975099)."
