KATHMANDU, Nepal — Nepal resumed its stalled coronavirus vaccination campaign on Tuesday with 1 million doses given by China after the Himalayan nation made international pleas for help.

Thousands of 64-year-old people lined up at vaccination centers even before they opened. People ages 60-63 are scheduled to be eligible for shots in coming days.

Nepal’s vaccination campaign began in January but stalled when neighboring India suffered a coronavirus surge and banned exports of the AstraZeneca vaccine it produces. Nepal had received 1 million AstraZeneca doses donated by India and paid for 2 million more but never received half the shipment.

That left 1.4 million people over age 65 who had received an initial dose of AstraZeneca vaccine uncertain if they would receive their second shot.

Desperate Nepal made several pleas to foreign governments and international donor agencies. President Bidhya Devi Bhandari made calls to the Chinese leader and wrote to the presidents of India, the United States and Britain.

Another 1 million doses donated by China arrived this month.
