The tiny nation wedged between India and China said that 470,000 people out of 770,000 in total had been administered the first shot of a two-dose regime of the AstraZeneca-Oxford vaccine donated by India.
Its rapid rollout puts Bhutan far ahead of other leading nations in reaching the 60-percent mark, including the Seychelles, Israel and the United Arab Emirates.
When Bhutan’s campaign launched on March 27, it set the speedy target of vaccinating 533,000 adults — having excluded pregnant women, new mothers, people with certain health conditions and seriously ill patients — in just one week.
However the nation, famous for measuring gross national happiness, extended its deadline by several weeks.
A health ministry spokeswoman said that healthcare officers were now focusing on vaccinating those above 70 as well as disabled residents.
The country has recorded 896 Covid-19 infections and one death so far.
