And yet another study investigating millions of cases that demonstrates the efficacy of COVID-19 #vaccines. #vaccination #vaccine #COVID19

Background Coronavirus disease 2019 (COVID-19), first identified in Wuhan in 2019, rapidly escalated into a global pandemic. Austria reported its initial cases in February 2020, resulting in millions of infections and thousands of deaths. This study investigates COVID-19 mortality across Austrian districts, analyzing factors such as age, sex, immigrant background, household size, education and vaccination status. Methods We analyzed data from the Austrian National Public Health Institute, comprising 4,591,739 confirmed cases and 20,123 deaths as of July 2022. We used a linear mixed model to examine whether individuals died from COVID-19. Furthermore, we created three interaction models: (i) vaccination status and consecutive month, (ii) age and consecutive month and (iii) sex and consecutive month. Additional linear models examined household size, education, and citizenship at the district level. Results Our findings highlight several determinants of COVID-19 mortality in Austria. Advanced age significantly increases mortality risk, while vaccination is strongly protective. Female sex is also associated with reduced mortality. District of residence influences the case fatality ratio, with notable geographic variation. Larger household sizes correlate with increased infection risk. Districts with higher proportions of residents with tertiary education exhibit lower infection and mortality ratio. Districts with a greater percentage of non-Austrian citizens have lower case fatality ratio, likely reflecting a younger population demography. Conclusion Key determinants of COVID-19 mortality include age, vaccination status, and sex. Districts with larger households experience higher infection ratios, while those with more highly educated residents have lower infection and mortality ratios. Districts with more non-Austrian citizens show lower case fatality ratios, likely due to younger populations. Further research into district-level age structures is warranted to refine these models. These findings underscore the importance of vaccination, particularly among older adults, and the need for accessible public health education to reduce infection and mortality ratio, especially in less-educated populations; however, district age structure (proportion of older individuals) substantially influences these associations.
In #NYC as of March 21, counts of #RSV cases and emergency department visits continue to drop, and we've only seen 5 deaths from #COVID in all of February, and 5 in the first three weeks of March!
There are slight increases in cases and emergency department visits for #COVID19 and the #flu so that's something to watch out for.
#COVIDIsNotOver as long as people are going to hospitals and dying, so I still #WearAMask in elevators, trains, planes, buses, hospitals, pharmacies and supermarkets!
There are many viruses which cause the "common cold"; some of those are coronaviruses and mutate fast, which is why there's never been a vaccine for the cold and might never be
Cliffton really nailed it here.
(Meanwhile there are microbiological reasons for the shared high mutation rate, but I know I don't understand implications of https://www.nature.com/articles/s41467-025-61555-x )
But this base fact is MULTIPLIED by two more things:
1) as jdm2 said the sheer number of hosts
corollary 1.A) Rare per person is not rare at pandemic billions-of-infections scale. People with rare one-in-a-million immune dysfunction can suffer long term SARS-CoV-2 infection and serial passage https://www.medrxiv.org/content/10.1101/2021.09.14.21263564v2 . The mainstream hypothesis says that these conditions are the origin of variants containing large jumps of 20+ mutations at a time
2) the viral volume per host while contagious. (Note re-gaining contagiousness does rarely occur.). And to my understanding, it turns out that since SARS-CoV-2 is a vascular disease, and our bodies have blood vessels everywhere, there's a lot of viable host tissue; simultaneous to that it has a higher viral copy count than several other common viruses https://pmc.ncbi.nlm.nih.gov/articles/PMC7476607/figure/fig2/
Here, we report the mutation rate of SARS-CoV-2, the virus responsible for COVID-19. We find that the secondary structure of the RNA-encoded viral genome is crucial to modulating the mutation rate and evolves under strong selective constraints.
