CDC Vaccine efficacy study appears to show unvaxxed less like to get covid
-
I haven’t seen this discussed yet anywhere.
If you google ‘cdc vaccine efficacy’ right now you’ll get this page https://www.cdc.gov/ncird/whats-new/covid-19-vaccine-effectiveness.html which presents one study, this one: https://www.cdc.gov/mmwr/volumes/73/wr/mm7304a2.htm
It appears to me that by the methods they use in the study to show that the latest booster was ~54% effective vs not having the booster, if you compare the boosted population against the completely unvaxxed population you get effectiveness of ~15-20%, and if you compare the completely unvaxxed population against the population of vaxxed but not with the latest booster, you see that the vaxxed population is ~40-60% more likely to get covid. This is back of the napkin calculation but the data are very obvious. The numbers I’m using are found if you search for the term ‘1,705’ in the paper, which is the number of negative tests among unvaxxed.
I’m not defending the methods used in the study – I’m not sure they make much sense. But I’m pointing out that using their own methods and their own data, the study appears to suggest that unvaxxed are more protected from covid than vaxxed. And this is not some random obscure study, it is *the* *one* study that CDC is presenting to demonstrate the latest vaccine effectiveness on their website.
I’m curious if anyone sees the same thing I do. There could be many explanations. Obviously, one might say that unvaxxed are more likely to have already got covid earlier and have better natural immunity so that’s why – which could be true, but that could maybe be teased out since they include data on past infections. Another suggestion could be that the vaccine harmed the immune system.
