Moderna receives FDA fast track designation for Zika vaccine mRNA-1893


19 August 2019 - Moderna today announced that the U.S. FDA has granted fast track designation for its investigational Zika vaccine (mRNA-1893) currently being evaluated in a Phase 1 study for the prevention of Zika virus infection in healthy adults.

mRNA-1893 contains an mRNA sequence encoding for the structural proteins of Zika virus and is designed to cause cells to secrete virus-like particles, mimicking the response of the cell after natural infection. Preclinical data published in The Journal of Infectious Diseases have shown that vaccination with mRNA-1893 protected against transmission of Zika virus during pregnancy in mice. 

mRNA-1893 is currently in a Phase 1 study evaluating safety, pharmacokinetics and pharmacodynamics in healthy volunteers.
