Dr. Pai and Dr. Gagnon, I'll go back to the obstacles to providing the vaccine and getting this whole process going from A to Z without any interruption.
Could the two of you list, in priority, what the obstacles looked like, from the patents and licensing to the delivery of the vaccines, to the infrastructure and the resources that you had on the donor side and recipient side? Would you be able to list, in priority, where the obstacles were for a complete vaccination to take place?
