This paper will answer two questions related to whether there is a need for sanctions for those who refuse to be vaccinated, what sanctions are appropriate from the perspective of interest theory, and what is the legal basis for imposing sanctions for those who refuse to be vaccinated in Indonesia. This study uses a sociolegal approach from the perspective of interest theory, it is found that sanctions can not only be given but must be given to those who refuse to be vaccinated. According to this perspective, the appropriate sanction is not fines or imprisonment, but deprivation of the right to socialize. The legal basis for imposing sanctions for those who refuse to be vaccinated is Article 5 of Law 4/1984 and PerPres12/2021. The sanctions referred to are administrative in nature in the form of termination of social security or social assistance, postponement or termination of government administration services, and fines. These sanctions do not contribute to stopping the spread of the Covid-19 virus, so it is recommended that amendments to these provisions are necessary.
