no vaccine for under 50s says vaccine head in UK

I think OP is talking about the Covid vaccine, news earlier today.

I think they are taking the view that the younger population won’t need the coronavirus vaccine, so it will be for everyone who is at risk, but it’s not absolutely defined as yet. The worrying thing is that many younger people have suffered serious health problems from having the virus which are ongoing and could affect their health for many years.

Which vaccine do you mean, rootingpowder?
If you mean this year's flu vaccine then the normal rules apply I think.

You can also get it if you are under 50 in Scotland have certain health conditions.
Both my son and daughter are having theirs at the doctors next week.

My young nephew works for a large financial institution in London where all staff are offered flu vaccine.
They have been told this year, that it will not be happening, as there is not enough vaccine to go around.

No, she quite clearly said carers would get the vaccine. Like the flu vaccine now. You get it if you're a carer regardless of age.

Could you pay for one? My son aged 48 had one done last week, he’s pays every year to have a flu jab after he suffered a dose of flu a few years ago and understanding what a nasty thing it is.

I think it’s too early to think !
