NEW DELHI, India (AP) — India has tested its COVID-19 vaccine delivery system with a nationwide trial as it prepares to roll out an inoculation program to stem the coronavirus pandemic.

The exercise Saturday included data entry into an online platform for monitoring vaccine delivery, along with testing of cold storage and transportation arrangements for the vaccine.

The massive exercise came a day after a government-appointed panel of experts held a meeting to review the applications of potential vaccine candidates, including front-runner Covishield, developed by Oxford University and UK-based drugmaker AstraZeneca.

The government plans to inoculate 300 million people in the first phase of the vaccination program, which will include healthcare and front-line workers, police and military troops and those with underlying medical conditions over age 50.

India has confirmed more than 10.3 million coronavirus cases, second in the world to the US. More than 149,000 people have died in India, third behind the US (347,000) and Brazil (195,000).
