I'm 38 and asthmatic, have received the flu jab every year as far back as I can remember and been on daily meds since the age of 5
I was not on the CEV list (apparently was 1 course of steroids away from it) but suffer chest infections most winters and sometimes at the beginning of hayfever season (yep I have hayfever too), always requiring medical intervention and sometimes requiring hospitalisation.
The original list lumps me in somewhere near the bottom, which for me personally I am ok with as I can continue to work from home and have understanding employers, but for many others who 'just missed' the CEV criteria and have to continue to go to work facing people every day, I definitely think they should be prioritised over people slightly older but fit and healthy.
If you didn't know me, saw me out running, you would consider me young (ish! Lol) and healthy, but it's only thanks to daily medication and avoiding certain situations (such as smokers, office working when other staff have flu, additional meds to manage hayfever, not going out when it's extremely hot, humid or exceptionally cold) that I manage to maintain this balance.
It's normal for me now having lived with it all my life, but I definitely think vaccines shouldn't be given primarily just based on age
