No it isn't. Vaccines create immunity, that's the point. Also, what diseases that don't kill you also don't result in immunity? "There's no evidence of immunity" seems an absurd statement, we can literally see the antibodies people create in response to the infection. That seems like just looking for an excuse to attack the UK.

That's because flu isn't a single disease, it's a category of diseases, like cancer. People do build immunity to specific flu variants.
