Even the tens of millions of Covid tests Roche Holding AG is churning out won’t be enough this winter as infections surge across the northern hemisphere, says Chief Executive Officer Severin Schwan.

The Swiss giant is on pace to produce more than 80 million rapid antigen tests a month by the end of this year, along with the slower but highly accurate PCR tests that it’s been delivering globally since January. But even that will fall short of demand amid continuing supply bottlenecks, so health officials will have to keep prioritizing resources.
