Vaccination is one of the most effective methods of preventing infections in the general population and for public health in general. This practice provides direct benefits from vaccines as well as a form of indirect protection for people who are not immune (herd or social immunity). In response to the COVID-19 pandemic, vaccines were recently released in an emergency release to prevent the virus's spread. The COVID-19 vaccines protect against disease by inducing an immune response to the SARS-Cov-2 virus. Vaccination increases the likelihood of developing the illness and its consequences. As a result, the goal of this study is to raise awareness among healthcare professionals about the importance of proper and efficient administration, including the safekeeping of COVID-19 vaccines prior to administering them to community patients.

Given the demographics of the respondents, it is significant that the majority of them are female and hold a college degree. These are reliable statistics because female nurses outnumber male nurses in the Philippines. Furthermore, because the vast majority of respondents have been in the service for more than four years and have attended at least one training and seminar, they are eligible to become nurse vaccinators. In general, nurse vaccinators in Lanao del Sur are well-versed in vaccine administration. Furthermore, it can be concluded that nurse vaccinators in Lanao del Sur are fully aware of the safe administration of vaccines from the pre-vaccination period to the post-vaccination monitoring and surveillance. It is critical for nurse vaccinators to be fully aware of these issues in order to avoid causing harm to patients.

Based on the findings of the study, the following recommendations are given.

(IPHO) and City Health Office (CHO) are encourage to strengthen its supervision and leadership with regards to safe vaccine administration. It is also recommended that an extensive trainings and seminars on vaccination will be done to increase the awareness of the nurses on the proper and safe vaccine administration. 2. The Department of Health (DOH) are encourage to strengthen its standard procedure and guidelines to expand the program on vaccination to ensure the safety of vaccine administration and avoid any harm to patients. Also, they are encouraged to strategically plan the vaccination process and administration in order to achieve Herd Immunity in the country. 3. The IPHO and CHO nurses may consider to continue professional education as only a few of the respondents were master's degree and doctorate degree holder. This will help them improve their knowledge and skills on their chosen field and provide the necessary skills to ensure a safe vaccine administration. 4. The nursing students are highly encouraged to put into mind and heart the knowledge and skills that they have and will be learning in school. This will help them become a good nurse that will provide quality service to patients. Further, they are encouraged to be informed and practice how to administer vaccines safely. 5. Lastly, the future researchers may consider to study the problems encountered by the IPHO and CHO nurses during vaccine administration. This will help them may necessary changes and actions that will avoid these problems in the future. The result of the problem may serve as a framework for future researches.
