Today we’re making some changes to our data sources — the next big step in how we report global Covid-19 vaccine data.
When we launched the Bloomberg Vaccine Tracker in December 2020, our data was entered entirely by hand. Government reporting methods were constantly in flux well into 2021, and we determined that the only way to ensure accuracy and timeliness was to have people review each website, every day. At its peak, our team grew to more than 60 newsroom volunteers, in addition to dozens more around the globe who helped chase down Covid-19 vaccine statistics from local health authorities.
