Particle size distributions of placebo vaccine (gray) and placebo vaccine with GLA (black) before (solid line) and after lyophilization and reconstitution (dashed line). Initial liquid particle size distributions were very similar for both formulations. After lyophilization and reconstitution, only a slight increase in particle size distribution was seen in the formulation containing GLA.
