Words Matter: PSA Part 3

PSA Part 3
As promised, here is the 2012 study that found an increased risk for SOME "non-influenza viruses" for SOME people who got flu shots: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3404712/
We note that it also found a LOWERED risk for some OTHER "non-influenza viruses" for SOME people who got flu shots.
And we want to repeat: this study does NOT show anything about SARS-CoV-2 (the virus). It also does NOT show anything about COVID-19 (the serious lung complications SOME people get FROM the virus).
The study DOES show that an increased risk of developing other, older, and generally milder coronavirus strains of coronavirus, specifically, coronavirus types NL63, HKU1, 229E, and OC43.
Words matter, so please be very, very careful with what you claim does and does not happen.
Our words: why the HELL isn't anyone collecting data on whether or not those with the most severe complications from SARS-CoV-2 got flu shots beforehand, say, within the last 6 months?
