There was an even larger French study that found exactly the opposite results. Imagine that. Whats more there are doctors from all over the world reporting that it does work. And that the side effects are minimal. And it saved a near 100 year old women with heart problems from the virus.
The mere fact that CNN is reporting it tells you all that you need to know.
I saw a story from several weeks ago where hydroxychloroquine was used on 80 patients in France.
78 of them recovered.
