Dear Peter, I agree with your comments. When Bill or we said about the sufficient vaccine doses are required, we do not forget about the epidemiology and sero-survey. As you mentioned they are must require. But the vaccine doses are key. If you think of the current situation, many countries till date have not used vaccine to control the disease and have no contingency plan yet to use vaccine soon in future as financially and technically they are not sound to prepare and use it. Therefore they need help for supply of vaccine doses extraneously.
