SEOUL (REUTERS) – As North Korea battles its first known Covid-19 outbreak, a lack of storage, chronic power shortages and inadequately trained medical staff pose acute challenges to inoculating its 25 million people – even with outside help, analysts said.
North Korea has not responded to offers of aid from South Korea and international vaccine-sharing programmes, but prefers United States-made Moderna and Pfizer over China’s Sinovac or British-Swedish Astrazeneca shots, according to South Korean officials.
Both the US vaccines rely on technology known as mRNA, and require super-cold storage.
Sinovac and AstraZeneca vaccines can be transported and stored at normal refrigerator temperatures.
“Moderna and Pfizer vaccines require a low-temperature storage system, which North Korea does not have,” said Dr Moon Jin-soo, director of the Institute for Health and Unification Studies at Seoul National University. “It would require a ton of additional materials to use them for inoculation.”
South Korean officials have said it is not clear whether the North has access to such storage systems.
In March, the United Nations (UN) Security Council gave a sanctions exemption to the Unicef to ship such “cold-chain” equipment to North Korea to assist with vaccinations.
The items included three walk-in cold rooms for “storage of routine immunisation vaccines”, though it was not immediately confirmed whether they had been shipped amid strict border restrictions.
According to the North Korea’s latest Voluntary National Review report presented to the UN last year, only 34.6 per cent of its population had access to electricity, and the country’s roads and railways were, “in general, not in standard condition”.
Given those conditions, only few cities could accommodate the cold storage units, experts said.
Whether North Korea can mobilise trained medical personnel on a large scale for a nationwide inoculation campaign also remains an open question.
Dr Jacob Lee, a professor of infectious diseases at South Korea’s Hallym University School of Medicine, said: “You need a system and trained medical experts to distribute the doses and inject the shots. I doubt the North has that.”
North Korea has inoculated children for diseases such as tuberculosis with the help of international organisations.
But UN aid agencies and most other relief groups have pulled out of the country amid extended border shutdowns.
