That’s the price for the US I think. It doesn’t give a price for the UK. Google tells me that flu jabs in the US cost around $70 without insurance. Like you said, flu jabs here are £10-15 for those not eligible for free ones. If the covid jabs follow the same pattern they shouldn’t be more than £20. At least I really hope that’s the case, £100 a shot will surely out-price 50%+ of people that pay for flu jabs.
