When you say not offered do you mean you can't get it or it's not free?They do not offer it to most people in the UK. ( the flu jab )
Flu mutates every year so they tweak the vaccine to the variant they think will be a problem in the coming flu season, they got it badly wrong in the UK 3/4 years ago!
As for C -19, death numbers in the UK have been totally inflated by the government and in real terms the people who have died of C-19 under 50 is something like 330 out of a population in that age range of some 50 million in the UK....that tells you all you need to know about having the vaccine!
Most have to pay here, I think it's around $20 which is half the cost of a doctors visit. A lot of companies will organise and pay for a shot for their staff though.
