As of this past summer, Massport isn't expecting numbers to hit 85% of pre-COVID until Q2 2022. Who knows if they have altered this since (their board meeting materials for the last 2 meetings aren't available yet). I think Q2 2022 sounds like a reasonable target.
I'm not sure those expectations from this past summer included a 95% efficacy vaccination being made available before the end of 2020. If I recall last summer, the hope was for a 50-75% efficacy vaccine by Q2 2021.
The past week's news from Pfizer-BioNtech, Moderna and AstaZeneca have been true gamechangers. The fact that Moderna's vaccine can be stored in -20 degree celsius freezers that already exist in most every pharmacy in the country is especially significant.
