- Health experts in India are testing out drones to deliver vaccines to isolated communities to help tackle the country's COVID-19 crisis.
- The purpose of these drones is to achieve faster vaccine delivery straight to citizens' doorsteps and improve healthcare access.
- For several years elsewhere in the world, drones have been delivering medical goods - for example, to help the Ebola outbreak in Liberia.
- There is a new urgency for the public and private sector to collaborate on India's drone applications, to improve healthcare equity in rural areas.
Villagers in remote corners of rural India could start seeing curious flying objects in the skies as health experts test out drones to deliver COVID-19 vaccines to isolated communities amid a deadly surge in coronavirus cases.
The southern state of Telangana, which is part of the World Economic Forum's (WEF) Medicine from the Sky project along with government think-tank NITI Aayog and Apollo Hospitals, will run a trial and then launch COVID-19 vaccine deliveries with drones.
Karnataka, another southern state, is also looking at drone deliveries of COVID-19 vaccines, while the Indian Council of Medical Research has been granted permission to do a broader study on the issue.

"These permissions (are) intended to achieve the dual objectives of faster vaccine delivery and improved healthcare access by ensuring primary healthcare delivery at the citizen's doorstep," the civil aviation ministry said.
The ministry regulates the use of drones, also known as unmanned aerial vehicles (UAVs), because they are seen as a national security issue.
Across the world, drones have been delivering medical goods for several years now, with charity Doctors Without Borders (MSF) testing them during a tuberculosis outbreak in Papua New Guinea in 2014, and to help tackle Ebola in Liberia.
Rwanda used Zipline drones to deliver blood to rural clinics, with the vehicles now carrying about 35% of the blood transfusion supply outside the capital.
During the coronavirus pandemic, Zipline drones have also been dropping off AstraZeneca's COVID-19 vaccines in Ghana, and will soon start delivering them in Rwanda and the United States, with Nigeria also planned for later this year.
Gavi, the global vaccine alliance, has tied up with California-based Zipline and the UPS Foundation to deliver vaccines in areas "without the infrastructure for conventional delivery", said Moz Siddiqui, head of Gavi's private sector partnerships and innovation.
"With every dose of the COVID-19 vaccine being so important, it is critical to ensure that countries have the support and tools to deliver vaccines effectively and efficiently to those who need them," he told the Thomson Reuters Foundation.
"Drones enable us to supplement more traditional delivery systems. They are a great, unique solution to a problem faced by multiple countries."
The global market for drone services - from product delivery to aerial photography, mapping, environmental monitoring and storm tracking - is forecast to reach $64 billion by 2025, up from just $4.4 billion in 2018.
There was a surge in interest in drones last year as the pandemic kept people home, and again as vaccines were rolled out.
German start-up Wingcopter is working on trial projects in Africa and Southeast Asia to deliver COVID-19 vaccines.
North American company Draganfly is also transporting COVID-19 vaccines, while start-up Volansi has partnered with drugmaker Merck to deliver vaccines in rural North Carolina.
The pandemic has highlighted the challenge in reaching rural and poorer communities, and the role drones could play in improving access to healthcare and medical supply chains, said Vignesh Santhanam at the WEF's aerospace and drones unit in India.
The Medicine from the Sky initiative, launched in 2019, expects to kick off its trials in Telangana state soon, and plans to expand its network within the state before partnering with other states, he said.
"We have kept our focus on vaccine delivery, although we see tremendous potential for other uses including transporting blood, medicines, and other essential medical goods," he added.
India's daily death toll rose to a record 4,529 on Wednesday 19th May, with a reported 267,334 new daily infections taking its tally to 25.5 million, the highest after the United States.
Cases have overwhelmed the country's rural areas, where ill-equipped health centres, staff shortages and long journeys have made it harder for villagers to access treatment and vaccines.
Drones are particularly useful in places where road connectivity and refrigerated transport are a challenge.
What is the World Economic Forum doing about the Fourth Industrial Revolution?
The World Economic Forum was the first to draw the world’s attention to the Fourth Industrial Revolution, the current period of unprecedented change driven by rapid technological advances. Policies, norms and regulations have not been able to keep up with the pace of innovation, creating a growing need to fill this gap.
The Forum established the Centre for the Fourth Industrial Revolution Network in 2017 to ensure that new and emerging technologies will help—not harm—humanity in the future. Headquartered in San Francisco, the network launched centres in China, India and Japan in 2018 and is rapidly establishing locally-run Affiliate Centres in many countries around the world.
The global network is working closely with partners from government, business, academia and civil society to co-design and pilot agile frameworks for governing new and emerging technologies, including artificial intelligence (AI), autonomous vehicles, blockchain, data policy, digital trade, drones, internet of things (IoT), precision medicine and environmental innovations.

"The vision is to ensure healthcare equity for rural areas," said Jayesh Ranjan, Telangana's principal secretary of information technology and industries.
While it may take a while for drone deliveries in healthcare to scale up in India, new regulations will help, Santhanam said.
"COVID has accelerated the use of drones in healthcare around the world. In India, it has created a new urgency for the public and private sector to collaborate on drone applications," he added.
