access to MS treatment abroad

Hi… I think I accidentally managed to delete my previous post… so here we go again!

In a nutshell, my enquiry was about free/cheap access to MS treatment if I decide to move abroad.

I understand, for instance, that Australia has a Reciprocal Health Care Agreement with the UK (and Italy, where I’m from). This means I should be able to get access the Australian PBS scheme (it lists all of the medicines available to be dispensed to patients at a Government-subsidised price) and obtain my medication (Plegridy) at a “small” price.

Does anyone know if there’s a list of countries which have signed similar agreements?
