To be perfectly frank, I didn't even think we would have vaccines in January 2021. That was the most optimistic scenario. The fact that we do have them is absolutely wonderful.
The first vaccines that became available were based on a new platform and a fairly complex production process. As I said, scaling up mass production is not just a matter of adding a bit more water to a bigger boiler, so it was to be expected that we would encounter shortages and hiccups along the way.
We may not be where we'd hoped at this point, but as you know, this is a marathon. What matters is not where you start, but where you finish. I have no doubt that the pace and scale of vaccination will pick up significantly in the coming months. I sincerely hope so, anyway.
