Agree. I lack time to reproduce from ourwordindata.org site his charts. Maybe later I will find the precise links and post them here. In meantime I just collected in one small PDF here his charts:
If I recall correctly, one was considered fully vaccinated only after two weeks have passed since their second mRNA shot.
If a person got the shot(s) but died before they would have been counted as fully vaccinated the death was counted as an "unvaccinated".
Unless they have corrected for the above when creating the charts I personally have a hard time trusting such data.
