I 100% guarantee there is absolutely no way the entire adult population is vaccinated ever. In the latest polling 20% of people still say they will never get the vaccine. Best case is 80% vaccinated but probably 70-75% would be good depending on if/when children get approved. It’s still conceivable to have 200M+ vaccinated by end of June. It would be really difficult to achieve with just Pfizer and Moderna alone, you would need flawless manufacturing and delivery for 6 months which is unlikely, but you have JnJ, AstraZeneca, and Novavax all also potentially getting approved between now and the end of June. It’s too soon to say whether we will have the supply to meet that goal. Too many variables.
On the vaccination side I think it’s conceivable to ramp up quickly. We are fast approaching 1M vaccinations a day and most of the large chains aren’t even involved yet. In that article posted earlier, CVS alone said they have the capacity to do 1M shots a day so its conceivable that when you add in all the other chains you could double that and then add in large stadium sites and/or hospitals or medical centers doing it and I don’t think it’s far fetched to assume we could ramp up to 3M vaccinations a day. As posted earlier that’s the peak level of daily vaccinations for flu shots so we have reached that level without billions in federal funding. If we have the doses, once this is ramped up fully I think it will be supply delays that will cause bottlenecks not inability to vaccinate fast enough.
