Southeast Asian countries are actively working to procure and use coronavirus vaccines.
In Singapore, Prime Minister Lee Hsien Loong received his first shot on Friday. Lee urged people in the country to take the vaccine in order to bring the pandemic under control.
Singapore is using a vaccine developed by US drug maker Pfizer and Germany's BioNTec from December.
In Laos, where the number of infections stands at 41, the government said it vaccinated about 100 people, including medical workers, in November and December.
It added there have been no side effects.
The vaccinations began after Chinese drug-maker Sinopharm provided 2,000 doses to Laos.
The vaccine was used on an emergency basis in China in July. The Chinese government officially authorized its use in December.
