Tomato, tomahto. Point being - vaccine distribution is a mess. I think 80% vaccinated would be nice, that won't be by July or so, which is when it needs to be for fall to be in person.
We didn't run out of vaccines. There are still vaccines yet to be distributed. What you probably meant to say was that the inbound order of vaccines from one of two accepted suppliers will be less than expected over the next three weeks with one week in particular having no incoming vaccines.
