COVID-19 Outbreak Information Updates (Reboot) [over 150.000,000 US cases (est.), 6,422,520 US hospitilizations, 1,148,691 US deaths.]

Then why state a distinction in the title of that column, if unvax and partial vax are essentially the same? If the data set didn't distinguish, then that seems to be a fault with the data collection. Again, I just find it odd. Shouldn't one dose be better than no dose? This graph could be a good opportunity to showcase why someone should at least get their first dose (unless the data and resulting additional column wouldn't support that notion).
If you just say unvaxxed, then people will ask about "partially vaxxed". If you put "partially vaxxed" in a column of its own and it shows even the slightest protection, you get people thinking that they can just get the first dose. If you put "partially vaxxed" in a column of its own and its show no protection similar to being unvaxxed, you get people saying, "see, the vaccine doesn't work".

No vaccination and "partially vaccinated" are really the same, because immunity isn't achieved with only the first dose. Therefore, they should be together.
