Johnson & Johnson working on booster for coronavirus variants, CEO says


Johnson & Johnson is currently working on a booster to help its Covid-19 vaccine deal with coronavirus variants, CEO Alex Gorsky told CNN’s Jim Sciutto on Monday.

“While we’re encouraged and we’re confident in the current vaccine that we have, you’ve always got to be preparing for the future, and frankly for the unknown,” Gorsky said. “So, we’re doing that as we speak.”
