I saw a feature on 60 Minutes last night about the task force that's getting ready to send vaccines out - it's a brutally tough task, and they can only do so much.
They said they need drastic amounts of cold storage to deliver - which is a huge logistics concern. Then... you have the issue of availability... they interviewed the head of the NJ response team, and she said she would get roughly 100,000 doses, good enough for 50,000 people initially - she needs about 500,000 just for medical personnel and workers.
It's going to be a while before the average citizen can get this stuff... but every bit helps, and slowly but surely we will get there.
