Yup! Lots of past threads on it can be found through the search function on here.
I was never interested because of the once-daily aspect, so I imagine this would make it more interesting to a lot of people (I was absent-minded even before MS, so I just didn't think I'd do well complying with this schedule!).
It is the lone injectable that is not an interferon and so acts differently to modify the disease. (Avonex, Rebif, Betaseron = interferons. Copaxone is Glatiramer Acetate.)
I'll be honest, another reason I gave it a miss was the possibility of welts and lipoatrophy. What can I say? I'm vain! However I do think the latter is significantly lessened with vigilant injection site rotation. And now with the reformulation meaning fewer than half of the injections in the first place, I imagine the risk goes down even further. Another reason the news you mention is great!
There are loads of past and present users on here. I'm sure they'll stop by too.
That's good news for lots of folks.
