If they couldn't do it for Covid vaccines, what makes you think they will be able to fo it for imfluenza ?

For example: deaths. Look at the Pfizer RCT trial results. There were more deaths in the vaccine arm than the placebo arm. The extra deaths were mostly cardiac/clotting related.
There's a reason so many people are confused about this. Governments, academics and media conflate COVID-induced mortality and overall mortality because if they admitted that COVID vaccines could kill a healthy person, it would have led to lots of people at low risk from COVID to not take the vaccines, so they pretended that there are no side effects or only very trivial side effects. But that's not how it works. You have to weigh all the benefits against all the costs. Inject people with a lethal dose of battery acid and then claim the resulting deaths are all a coincidence, and you'll discover it's incredibly effective drug against COVID mortality! But that doesn't mean you actually solved any problem. It's just a statistical artifact caused by dishonesty about side effects.
For another example: reducing the spread. No it didn't. Firstly, again, the RCTs didn't even attempt to measure this because you can't. Think about it. So any such claims must rely on inference from dubious observational evidence. But secondly, the observational evidence says the opposite. If what you say was true then cases could not have been higher in 2022 when the majority was fully vaxxed than they were in 2021 or 2020, yet that is the case.
Those are just two of the problems with how the authorities work with the data. Even the apparent claims of effectiveness against infection in the early days turn out to be wrong because of a methodological error (deliberate or otherwise) in how the trials and observational data was processed. In reality the vaccines may never have worked.
It's all very unfortunate.
Influenza is well understood by now and has had decades to research
