From which I quote, and not for the first time, in response to you.
"Therefore, the results of this study cannot and should not be interpreted to represent any sort of relationship or association of influenza vaccination receipt and COVID-19 illness.Results from this study DO NOT support the anti-vaccination viewpoint of avoiding seasonal influenza vaccination, and in fact should be interpreted in the opposite manner, since significant protection against influenza was associated with vaccination receipt, and a slight decrease in the odds of infection from other respiratory viruses was also noted. Results from this study should not be applied to or interpreted with COVID-19 in any way."
The study looking at increased risk of non-influenza infection due to TIV was tiny with only 115 participants and a smaller number of infections. They report a headline risk ratio of 4.4 (1.31-14.8) but when they added a couple of confirmed but unreported infections the risk ratio changed to 3.46 (1.19-10.1) getting even closer to no statistical significance. And seeing as you reckon PCR testing is faulty you should disregard this study totally as that is what they used to confirm and classify the various viral infections.
And here's some anecdata for you. Ever since I've been getting the flu shot, my frequency of catching colds has reduced by a factor of 10.
