Moderna Inc (MRNA.O) has offered to sell its COVID-19 vaccines to the African Union at $7 a shot, head of the Africa Centres for Disease Control John Nkengasong said on Thursday, half the price paid by the United States earlier in the year. It is also a substantial discount to what other buyers like the European Union have agreed this year, part of a broader trend for drugmakers to sell at lower prices to lower income countries. "I am happy to say that a dose of the Moderna vaccine will be $7. That is what is being offered to us," Nkengasong told a weekly virtual media briefing. Earlier this year, Moderna said its deals outside the United States had been struck at between $22 and $37 per dose. As those did not include a lower income country, this is the first insight into the kind of prices Moderna is prepared to charge poorer countries. Nkengasong said there was no doubt that a fourth wave of the pandemic was coming to Africa, where only 6% of the eligible population has been fully vaccinated. Africa has to date recorded 8.5 million cases and 220,000 deaths, said Nkengasong.
