> In today’s MMWR, a study of COVID-19 infections in Kentucky among people who were previously infected with SAR-CoV-2 shows that unvaccinated individuals are more than twice as likely to be reinfected with COVID-19 than those who were fully vaccinated after initially contracting the virus. These data further indicate that COVID-19 vaccines offer better protection than natural immunity alone and that vaccines, even after prior infection, help prevent reinfections.
- peteradio 5y agoI wanted to see this kind of comparison in a study but this pretty poor supporting evidence for vaccine > natural immunity. 1) Low number of people studied. 2) Voluntary testing!!! 3) Testing occurred during the sweet spot for vaccine effectiveness (vaccine would not have waned) 4) No delta variant!!! 5) Not stratified by age group!!! Can't we get a high statistics study with strict testing!? We have literally hundreds of millions of people who've been vaccinated, and there is no excuse to show me unstratified data as if a 20 year old has the same profile as a 60 year old.
- Miner49er 5y agoPretty sure it was stratified by age group? Other then that, I think your points stand.
- peteradio 5y agoHere's the PDF: https://www.cdc.gov/mmwr/volumes/70/wr/pdfs/mm7032e1-H.pdf https://www.cdc.gov/mmwr/volumes/70/wr/pdfs/mm7032e1-H.pdf my understanding is that they are "age matched" between the control and test groups (similar age distribution can be found in each). But I want the final result quoted per age bracket. By mixing age groups you may be reducing the impact for the most important ages.
