How large was the impact of accusations against Lucille Ball on the McCarthyism movement?

I don't know how to word my question as best as I could. But from what I remember learning, the accusations against Lucille Ball ultimately backfired on McCarthy. I'm just wondering if it had any larger impact in swaying the public against the McCarthyism movement. The fact that this came up in my classes makes me think it was significant. And I'm old enough to remember her show, and how big it was culturally.
