HANOI (REUTERS) - Vietnam has agreed to buy 30 million doses of the Covid-19 vaccine produced by AstraZeneca, the government said on Monday (Jan 4), adding that the authorities are also seeking to purchase vaccines from other sources, including Pfizer.

The South-east Asian country previously agreed to get a Russian vaccine, though also said it would not rush to secure vaccine deals, citing the potential for high financial costs and after managing to contain its coronavirus outbreaks. It has only 1,494 cases, with 35 deaths.

The AstraZeneca and Oxford University Covid-19 vaccine is cheaper than some others and can be stored at fridge temperature, which makes it easier to transport and use, particularly in developing countries.

"We've already signed an agreement to guarantee the AstraZeneca vaccine for 15 million people, which is equivalent to 30 million doses," deputy health minister Truong Quoc Cuong told a government meeting.

Vietnam is also in talks to purchase vaccines from Pfizer, Russia's Sputnik V and China, the deputy minister said.

Mr Cuong did not name the Chinese vaccine candidate.

He also said Vietnam would be eligible to buy vaccines from the Covax programme, a global vaccine alliance, to cover 16 per cent, or 15.6 million of its almost 98 million population, but said more information would be available in the first quarter of the year.

Covax is co-led by Gavi, the Vaccine Alliance, the World Health Organisation and the Coalition for Epidemic Preparedness Innovations.

Vietnam, which has yet to give formal regulatory approval to any vaccine, is also developing vaccines domestically.

The country has conducted human trials of its "Nano Covax" vaccine and a second home-grown vaccine is expected to start undergoing human trials this month.

Vietnam in August said it had signed up for 50 million to 150 million doses of the Russian vaccine, though delivery remains unclear.
