It’s not the sequencing that’s the issue. The article even says that one of the hardest things to crack is the lipid nanoparticle delivery mechanism.
If the WHO/UN/whomever wants to make that general technology public, they should buy it from them.
In the interim, Moderna has said it would help anyone manufacture the covid vaccine.
What the WHO is asking for goes well beyond that.
OP's article is just an anti-pharma hit piece.
