Pfizer’s chief financial officer has described the Covid pandemic as a 'multi-billion dollar franchise' — and expects profit to continue.

David Denton told investors in an earnings call last week his company's vaccine and antiviral would still be 'relevant for many years to come'.

The CFO said he expects the Covid virus to be 'somewhat like a flu... but more deadly' — meaning therapeutics will still have a massive role in controlling the virus.
