It's great to see that the supply of Invicorp has finally resumed.
As this is currently not available through the NHS I thought I'd mention cost here, as it is not cheap, so any potential savings for other people are worth passing on.
Having seen the injections advertised online at around £18 per dose and been quoted similar prices at local pharmacies, my prescription from Boots for 28 doses was £290. At approximately £10 per dose that is a huge difference.
I hope this is of use to others that need it.
