MGoH: Here is a very encouraging story in todays Observer.
Texas scientists’ new Covid-19 vaccine is cheaper, easier to make and patent-fre
And good to see a reminder that there are some great people doinggreat things in Texas.

On reading the article it gives the lie to "is cheaper, easier to make, and patent free"
It may become each of those things, the facts say that "it is still in development", and "they do not intend to patent it". Much can happen between now and when/if it becomes a proven, effective, vaccine.
