On December 14, Prime Minister Lee Hsien Loong disclosed the plans of vaccination for Singapore by stating that it will be free for every Singaporean.
However, accepting the vaccine from the Government will not be mandatory. The choice will be left up to you.
This approach does seem a bit weird, but given the circumstance of the vaccination being capable of reacting to certain medical conditions, it might be safer to wait for more information.
The priority of the vaccinations will be assigned to those working in the frontline to support the efforts against Covid-19, and as well as the elderly and vulnerable.
