I don’t recall any flu shot claiming to reduce transmission. Can’t see how you’d be able to run a clinical trial for preventing infection without a lot of people coughing on others. I can’t see whether this is a big concern as it reduced the severity of the disease which reduced the load on medical systems. As with any vaccine going back to the initial efforts with cowpox, the goal was/is to train your immune system to deal with the toxin without having to be infected by it. Pre omicron, countries with good vaccination rates had lower fatalities. Post omicron, to date at least, it behaves like a flu without flu shots - roll the dice and hope. We’ll see whether bivalent or otherwise updated boosters help. Or, just blow off vaccines and take your chances. Although it’s polite to avoid us old farts while doing so.
