Don’t have time to go out and get a flu shot? Now through Uber’s UberHealth service, you can have on-demand mobile flu shots come to you! During a one-day promotion last week, in select cities throughout the United States, from Atlanta to San Francisco, Uber Health would bring a nurse-administered flu shot right to your door. While this was a one-day offering, we’re sure that they’ll offer it again. (See below for a full list of cities in which Uber offered an Uber flushot.) And in the meantime, Uber has teamed up with AIDS-fighting program (RED) to raise money for the (RED) AIDS program.

With the holidays, you may not have heard about Justine Sacco, and her boneheaded Twitter tweet heard around the world. “Going to Africa,” she wrote, “hope I don’t get AIDS. Just kidding. I’m white!” she tweeted. Yes, really.
