Not disagreeing with this (although my understanding is that there have been studies that show vaccination has been more effective), but how would you seperate the unvaccinated / previously-infected-and-recovered cohorts?
Even by reconciling PCR testing data (which I imagine is incredibly patchy at best), you still would only know historically how many people tested positive (ignoring what is in all likelihood a majority of the cases that never got tested) and be able to reconcile it against numbers of vaccinated, which tells you nothing useful without being able to intersect the two sets (which you can’t do without uniquely identifying every PCR test and matching it to an individual universally).
i.e. the better data you would need doesn’t exist.
- dexen 5y agoThere's a recent (January 19, 2022) CDC publications with numbers on exactly that. Forbes provides a brief overview: "CDC: Prior Covid Infection Offered More Protection Against Delta Than Vaccines — But Both Together Did Best" https://www.forbes.com/sites/joewalsh/2022/01/19/cdc-prior-covid-infection-offered-more-protection-against-delta-than-vaccines---but-both-together-did-best/?sh=500d15ba3d04 https://www.forbes.com/sites/joewalsh/2022/01/19/cdc-prior-c...
- teh_infallible 5y agoCurrently, people who only got one shot or got their second one less than two weeks ago are being counted as “unvaccinated” which seems disingenuous at best.
- wongarsu 5y agoIf that data doesn't exist then that's just because it isn't tracked. Here in Germany if you test positive on a PCR test you have to quarantine for 14 days, then you get a proof of recovery which for 6 months you can use like a proof of vaccination (which you need for non-essential shops, gyms, etc when the 7-day incidence is too high, like right now). As a result, tracking numbers for the "recovered" cohort isn't a problem. Obviously the "unvaccinated" group will always contains some unknown number of recovered people we don't know about, but at large enough effect sizes that isn't a problem.
