Help 😁

Okay I know a lot of people don't post much on here but my BIL has MS.  He just went to get back on his shots because he has been off of them for 6 years, so anyway his neurologist told him to get back on the shots ASAP but his co-pay is $1,010 😳.   Humania does not cover this med, is there a program or other insurance that you know if he can try, he is on a fixed income and I'm just floored Humania doesn't cover this shot.  Any and all help is appreciated.
