The purpose of this paper is to discuss potential legal complications as well as the protection of health care employees involved in COVID-19 immunization services at HSFs. COVID-19 instances are increasing at an alarming rate, and strict health norms are falling behind. COVID-19 vaccinations are critical to halting the virus's transmission in the community, reducing disease-related suffering and mortality, boosting herd immunity, and protecting the community from COVID-19 while social and economic activities are restored. COVID-19 vaccination, on the other hand, continues to confront obstacles as a result of public rejection. This scientific publication is based on a normative legal approach. The public's refusal of the COVID-19 vaccine results in a plethora of complications, including public misconceptions and suspicions of vaccination conspiracies by healthcare professionals. According to a review of the literature, health workers who provide COVID-19 vaccination services in Indonesia are legally protected if they follow established procedures. Medical Practice Law No. 29 of 2004, Presidential Regulation No. 14 of 2021, Health Minister of Republic Indonesia Regulations No. 269 and 290, and Decree of the Minister of Public Health HK.01.07/Menkes/413/2020 concerning Coronavirus Disease Prevention and Control 2019 all provide legal protection for health workers.

In fact, environmental issues have a high complexity. With the existing scope, it seems that the juridical instrument for enforcing environmental issues, namely environmental law, becomes an urgency in order to realize environmental integrity for sustainable development. These legal arrangements are needed to regulate environmental management so that the community has a legal basis that is used as a guide in environmental management based on sustainable development. If you look at the existing reality related to environmental law instruments, the existing regulations on environmental law are prepared by following the needs of environmental protection and integrity. The research method used in this research is normative-juridical which is done by examining library materials or only secondary materials. In relation to the problems presented, it leads to the conclusion that the regulation of environmental law itself has experienced quite a significant development. However, with this significant development, there are still various problematic environmental issues which make the validation of environmental law instruments, which instruments are still weak in enforcement so that they have not been able to provide implications for efforts to fully achieve the predicted sustainable development goals
