The trials will be held at Kaiser Permanente Washington Health Research Institute in Seattle. Testing will involve 45 young, healthy volunteers and it uses Moderna‘s mRNA-1273 vaccine.

„Unlike a normal vaccine, RNA vaccines work by introducing an mRNA sequence (the molecule which tells cells what to build) which is coded for a disease-specific antigen, once produced within the body, the antigen is recognized by the immune system, preparing it to fight the real thing,“ according to the University of Cambridge.
