unfortunately we ARE going to need it because at current rates, billions of people won't be vaccinated until 2022 or 2023: https://www.npr.org/sections/coronavirus-live-updates/2021/0...

That's billions of people who will be incubating more mutated variants of COVID-19.

And secondly, we'll need that equipment for COVID-19 variant booster shots.

(And will come in handy for vaccinating with a universal flu vaccine, even HIV, etc.)
