Pfizer, BioNTech and Moderna are making combined profits of $65,000 every minute from their highly successful Covid-19 vaccines while the world's poorest countries remain largely unvaccinated, according to a new analysis.

The companies have sold the vast majority of their doses to rich countries, leaving low-income nations in the lurch, said the People's Vaccine Alliance (PVA), a coalition campaigning for wider access to Covid vaccines, which based its calculations on the firms' own earning reports.

The Alliance estimates that the trio will make pre-tax profits of $34 billion this year between them, which works out to over $1,000 a second, $65,000 a minute or $93.5 million a day, AFP reports.

“It is obscene that just a few companies are making millions of dollars in profit every single hour, while just two per cent of people in low-income countries have been fully vaccinated against coronavirus,” Maaza Seyoum of the African Alliance and PVA Africa said.
