Why we won't have enough vaccine for everybody sooner...
RNA vaccines are the new thing that enables scientists to create new vaccines overnight.
Once they have the blueprint of the virus they're trying to create a vaccine to fight, creating a new vaccine to fight it is plug-and-play... they can do it over a weekend.
This capability is a revolutionary thing... it's an extremely big deal... it's what allows us to rapidly tweak vaccines as the virus mutates...it's in the process of saving millions of lives... and is on the way to perhaps being Science's best thing ever (so far anyway)....
The main supply chain issue in making enough vaccine is the availability of "lipid nanoparticles".
Making this stuff went from being a very fringe thing a year ago to being a hugely big deal now.
The challenge for suppliers of this stuff is how to go from making a total of just a few hundred grams of lipid nanoparticles to making literally many tons of it. They know how. They can do it. But the immense scaling factor of going from making a tiny bit to making a huge amount is inherently something that takes time. You gotta make the machines that make the machines that perform the tasks you need to do in order to make the stuff.
Bumps in the road are to be expected, and this is one of them... this particular bump should have been expected... production of this stuff should have been ramped up a year ago, but wasn't... both the feds and the drug companies coulda-shoulda been on top of this sooner... they weren't... but they're on top of it now. It's the main supply chain factor in the race to make enough vaccine.
