“Fauci also said that there was no evidence that it would prevent the disease, as some have suggested”
It’s a treatment for the disease, not a preventative.
And apparently the treatment may include the antibiotic Azithromycin.
I have chatted with people who were Quarantined on one of the cruise ships until a few weeks ago.
They didn’t get the virus and said none of the people who were on hydroxychloroquine got it either. So yeah, there is evidence.
Here is a clue: evidence is still evidence even when the mainstream media suppresses it.
