The graphs are all doses combined, there's a section to list which dose it is in the reports but it's usually left blank you can see what dose it was if they added it in the individual reports here https://openvaers.com/covid-data/covid-reports

PRIOR_VAX: (is the category where it will be listed if they bothered, these reports take 30mins to an hour to write up so they're always rushed as you can hear in the latest veritas vid)
