Singapore has begun vaccinating people against the coronavirus.
The inoculation program started on Wednesday with a vaccine developed by US pharmaceutical giant Pfizer and Germany's BioNTech.
The government says about 30 health care workers at a national medical institution were vaccinated.
A 46-year-old nurse, who was the first to receive the vaccine, said it was a relief to get the jab because it will protect her and made her less concerned that she might spread the virus.
The medical workers reportedly will get a second shot on January 20.
The government plans to inoculate everyone in the country except those aged under 16 and pregnant women free of charge by the end of next year.
Priority will be given to health care workers and the elderly.
