$VXRT Here are the two Vaxart pumps. The first was caused by Fake news release by Vaxart about Operation Warp Speed involvement...The second recent one preceded the release of phase one results. Somebody leaked out information that was fake about the results.. that caused the second pump. The second was much more sophisticated and similar to how penny stocks are sometimes manipulated. My guess is the players were similar or the same in both instances.
