For some extra context, the NHS offers a free seasonal flu vaccine to vulnerable groups (similar eligibility to the Covid booster), and healthy adults can choose to purchase a seasonal flu vaccine at a pharmacy for about £10. Some people do this, and some employers pay for their employees to get vaccinated. So there is precedent for this kind of thing, and although I doubt it would get rolled out this year, this is a good time to plan for next year.
