Open Source is everywhere! (Hope it is OK to post this - I found it interesting).
Corbevax is a protein subunit COVID-19 vaccine
The vaccine is not patented and is planned to be openly licensed under COVAX
As of December 2021, Biological E announced positive results, but some experts criticized the lack of public data from phase III trials
On 28 December 2021, India approved the vaccine for emergency use
In January 2022 the scientists developing Corbevax have declared no G7 countries were yet funding the open source vaccine
