This is utterly disappointing and bs rhetoric - Africa CDC is an amazing health agency doing vital, collaborative work to ensure health access and equity. Something we should all strive towards.
Holy shit. HHS says the Africa CDC "is a powerless, fake organization attempting to manufacture credibility by repeating its claims publicly. It is not a reliable source, and its statements should be treated accordingly."
NEW: We're publishing an astonishing outburst the Dep of Health and Human Services left in our inbox.
In an unsolicited email about our coverage of a horrific vaccine experiment, the HHS insisted the Africa CDC was an unreliable source for information, calling it "fake" and "powerless."

Somewhat controversial take - I enjoyed TRON Ares. Mostly bc I went for the NIN soundtrack, awesome visual effects, & some decent action…and maybe points on AI ethics. It’s not Legacy, but it was fun to watch. You don’t go to a TRON movie (w/Leto) for the feels, but the fun experience.
