Re: A long way still to go
"Any reason you used the world in data site, and not the WHO?"
Our world in data do a really good of job of clearly presenting information - something that a time-pressed journalist would appreciate I imagine. They also do a lot of fact checking on it.
As for their source? For vaccine data they cite either the actual country's official data (which will also be going to the WHO, so same data) or for some nations they cite ... the WHO. So it's basically data from the same sources.
