I don't think there's going to be a single vaccine that's going to be the solution. A lot of that has to do with production capacity. We will have, hopefully, many successful safe and efficacious vaccines, and then we will see the manufacturing and production ability.
I understand from our colleagues in Swiftwater, Pennsylvania, that we may be producing 600 million doses if our COVID-19 candidate vaccine is successful, but you can see that 600 million per year is not going to take care of eight billion people.
Multiple vaccines will come into play. It will certainly not be a pharmaceutical company that's going to define how much it can produce, and where it's going to go. That will be decided by governments in regard to the previous agreements they may have had with pharmaceutical companies. There are also organizations that are looking at the ethical distribution of COVID-19 vaccines, and they will be involved.
Pamela, do you have any comments on that?
