AST accounts work in unexpected ways. Your new Vaxart shares will appear in a different account. You can either create a new login for that account, or ask AST to aggregate the VXRT shares into your existing AVIR zero share holding. I created a new login, but it may be better to just ask AST to aggregate the shares. I'm still waiting for the shares to be transferred to somewhere that I can sell them!
