3 years ago Hello @dprata00 , "unknown provider" means that the State is not making available the information on whether the vaccine is Pfizer, Moderna (or whatever becomes available in the future), so yes to your first guess.
On the COVID-19 vaccines data dictionary, the "unknown providers" are described as "COVID-19 vaccines from an unknown provider." I would like to have a better clarification for that definition, if possible to know if the unknown provider are vaccines where you guys could not identify if the vaccine is from Pfizer, Moderna, etc, or if those are vaccines from a provider different from Pfizer and Moderna, such as Johnson-and-Johnson.
