And how many flu jabs have you had over the years? Why do you think this is going to be any different?
That is exactly what we do every winter for every new strain of flu. And that vaccination has been shown to wear off inside 4 months. it's why they don't want to give the vaccination in eary autumn because it won't cover you for all of winter assuming that their best guess for which strain of flu is going to be dominant over winter & early spring is actually the correct guess.

Key Facts About Seasonal Flu Vaccine
If you're lucky, they'll "combine" or do both at the same time in years to come once research shows it is/is not as effective if it is/is not combined or at least done at the same time as the flu jab. I know that the pneumonia jab can be given at the same time as the fIu vaccination and each time a new variant is added to the pneumonia vaccine, both myself & my husband get called in for another shot (because pneumonia almost killed us both 4 or 5 years ago).
Various other vaccinations can be combined, but some have to be separate to others.
Hubby & I had a fair few before we went out cycling on tour.
Polio, Yellow fever, tick bourne encephalitis (hoping I spelt that correctly),
Rabies, tetanus, thyphus, japanese encephalitis, whooping cough, measles, mumps, rubella, Meningococcal, Hepatitis A, TB, to name just a few (1 or 2 of my childhood vaccinations didn't "take" so had to be repeated individually rather than combined - one in particular put me in picu as an infant and none of my siblings (full or 1/2 siblings) were allowed them as a result.
Some countries still have mandatory vaccination certificates needed to be shown before you are allowed to enter, yet I never heard of people complaining about mandatory vaccinations in order to enter a country (prior to Covid-19)... Odd really, Yellow fever is the main one that springs to mind. Without the original (paper) certificate, no entry period.

And despite data showing that you only need 1 dose for life-time protection (this changed recently from the one dose every 10 years) some 17 countries in the world will not permit a traveller entry unless their certificate is within the last 5 to 10 years. Yet no-one really complains about that because it doesn't affect the majority of those who
yell the loudest can be heard.
