About 1.1 bln Corona virus infection covid new estimates indicate that vaccine doses may have been thrown away by governments around the world.
Airfinity, a science and data analytics company, said its analysis showed a significant understatement of vaccine waste.
Publicly, a total of 158 million doses are said to have been discarded worldwide, Airfinity reported, citing newspaper reports and the government statements.
Much of this report does not specify which type of vaccine was rejected. Of those who named the manufacturer, the Russian “Sputnik V” has the highest numbers of losses (25 million doses). It is followed by AstraZeneca, which claims 19 million missed shots.
Airfinity’s analysis assumes a 10 percent waste rate from June 2021, when global dose exchange begins. This figure is derived from confirmed waste in the United States with an average shelf life of six months.
The UK vaccine loss rate is between 3 and 5 per cent, according to the analysis The Independent.
Airfinity estimates that 14 billion doses of vaccine have been delivered worldwide to date, of which 1.1 billion have been wasted and remain unused.
Dr Matt Linley, director of analytics at Airfinity, said: “Despite countries’ best efforts to avoid waste, some degree is inevitable.
“Large multi-dose vials can make it more difficult to improve efficiency, as well as cold-chain storage and predict daily demand, or simply a vial that has fallen or sat out too long.
“Vaccines in single-dose vials with longer shelf lives that are easier to transport and store will reduce waste over time.”
Airfinity CEO and co-founder Rasmus Bech Hansen said: “If we want a fast-reacting global vaccine response system, we will have to accept a certain level of missed doses. But the less the better, and ongoing monitoring of waste levels is an important part of global health information.”
Julia Kosgei, policy adviser for the global health campaigners the People’s Vaccine Alliance, said many of the Covid-19 vaccine losses were due to the “deeply uneven global response to this pandemic”.
She said: “These vaccines have been developed with unprecedented public funding and are set to become a global public good. But instead, vaccine monopolies have concentrated production and distribution in a few countries. And the needs of developing countries are seen as an afterthought.”
She added that governments are “dumping large quantities of doses, often close to their expiry dates, into developing countries without notice, leading to further losses”.
