Good news but still a long way to go. How's it going to be rolled out? Here in the UK we have tried and failed to get a regular flu jab (our GPs have run out of a very small supply and the pharmacies don't have any to sell) and I'm not optimistic about our chances of getting this next year or whenever it arrives.
Because GPs (in England, I don't know about the other nations) should have enough stock. They are prioritising higher need first, and then the expanded programme later in the year, and then anyone else who wants one after that.
If you're not priority need you can try a pharmacist.
