I explained the magnitude of numbers between the two groups. The data started in January 2, right in the middle of our largest wave. Vaccines did not roll out en masse until April, and only reached 50% in August. There were hundreds of thousands of unvaxxed cases before the vaccine was available. Therefore the total cases are not a good denominator because they skew heavily towards unvaxxed. That is why I am using total cases separated by each group as the denominator.
My interest was not in finding out how many people in each group got covid, but now they fared after getting covid because we have been told repeatedly that “the vax won’t protected you from covid but will protect you from hospitalization and death.”
You cannot normalize by total number of cases because of what I explained in the first paragraph. There were hundreds of thousands of cases before vaccines were even available. It is not a true picture.
Here is a chart to show our January - March cases, pre vax and you will see what I am talking about. https://www.worldometers.info/coronavirus/usa/georgia/
I. It’s have missed your explanation, and flipping back through the comment don’t see it, so please share.
Why compare unvaccinated hospitalization / deaths as a group with only breakthrough cases instead of the total vaccinated?
Adjust the case counts based on that. Shouldn’t be hard or complicated. But the percents you provided are like comparing apples to el caminos…
I see your point, that case fatality rate, and case hospitalization rate are not much different between vaccinated and unvaccinated (even though there were 15 times as many cases among the unvaccinated).
This is the reverse of what we have been hearing elsewhere (from multiple sources), about the vaccine effect providing stronger protection from hospitalization or death, than from infection.
Because this is an outlier, I’m hesitant to leap to conclusions. There are several potentially confounding variables. The timeframe is clearly a concern, mixing times with widely varying vaccination rates, with widely (and independently) varying case numbers. Delta variant is likely a significant factor, possibly waning vaccine effectiveness. Controlling for age and comorbidities could be huge.
It is definitely of interest, and something that deserves investigation, and explanation.
Good catch.
“Vaccines did not roll out en masse until April, and only reached 50% in August. “
With that information look at the daily deaths, they had decreased off of the January-March highs but vaccinations apparently were not the reason they decreased.

The “Total Coronavirus Deaths” trend is also interesting from this perspective.
