The Latest: Is 90% effective too good to be true?

Dear Reader,

There’s a lot of really good and really bad news related to Covid-19 this week. Let’s start with the good news: Pfizer and BioNTech released data suggesting that its vaccine is more than 90% effective at preventing Covid-19. There are caveats, which you can read here, but there are also real reasons to be optimistic. Dr. Anthony Fauci recently said a vaccine could be available to all Americans by April 2021.

The bad news is that heading into the holiday season, cases of Covid-19 continue to spread widely. U.S. hospitalizations from the virus hit a record high of nearly 62,000 on Tuesday, and new daily cases passed 139,000 for the first time. With a potential vaccine on the horizon, now is the time to be cautious.

P.S. Today I published a story about the success of Covid-19 long haulers at building a patient-led health movement. You can check it out here.

Here’s what else is new:

  • The decision applies only to people newly infected with the virus and came with a warning that it should not be used in hospitalized patients, the New York Times reports.
  • The taskforce will be led by three co-chairs: former Surgeon General Vivek Murthy, former Food and Drug Administration Commissioner David Kessler, and Dr. Marcella Nunez-Smith from Yale University. Read more.
  • Trump adviser David Bossie tested positive for the virus. Housing and Urban Development Secretary Ben Carson also tested positive recently.

Be well,
