Hey, secret history fans. I'm Lizzie O'Leary, the host of What Next TBD. What Next is Slate's

Daily News Show, and every Friday, I'm in the feed, turning the news of the present into a look

at the future. What Next TBD is our glimpse at technology, power, and how the future will be determined.

From fake news to fake meat, augmented reality to MRNA, I talked to a lot

of experts about the technology that's reshaping our world and the people whose lives are being

turned upside down. If you like secret history of the future, you probably already know that

technological advances are not always what they seem. So if you miss that show, maybe What Next

TBD can be your new guide to what matters, what doesn't, and what's next. So you're about to hear

an episode of the show. It is about booster shots. If you like what you hear, subscribe to What Next or

What Next TBD in its own feet. Thanks a lot.

to be eligible for a third shot, starting as early as September 20th.

It will make you safer and for longer, and it will help us end the pandemic faster.

And hearing that made me wonder.

Will it?

I don't know, honestly.

That's Saad Omer, the director of the Yale Institute for Global Health.

So there are two things, two variables there.
