If I received a W2C that has changes for social security and medicare ONLY, do I need to file an amended return for my 2015 tax year.

I was exempt from paying SS and Medicare due to my immigration visa status. I received a W2C from my employer when I was refunded that amount, and the only correction is in the SS and Medicare boxes. There are no changes to anything else. Do I still need to file an amended return?

No, there is no income tax change so no amended return is necessary.

Those boxes have no impact on the other items on the tax return. 

You can if you want to, or need to do it for some other reason.
