This study determined the problems in the current COVID-19 vaccination process in the National Capital Region
(NCR) and proposed improvements to improve the current process. A survey questionnaire to gather information on
vaccination experience was created using Google Forms and was deployed to 120 respondents. The current
vaccination process was presented using a systems flowchart, while the problems observed in the process were
evaluated using a stream diagnostic chart. Findings showed that citizens experienced a delay during vaccination due
to the inefficiencies of the online registration system, the first step in the current COVID-19 vaccination process, and
insufficient resources in the vaccination site. An improved COVID-19 online registration system was designed to
improve the registration process. This improved system will facilitate a more efficient vaccination process and provide
more reliable information readily available for LGUs. It is also recommended to increase the workforce available in
the vaccination site to assist the citizens seeking the service. An integrated or unified vaccine registration and
scheduling system may be studied and created in the future so that all LGUs will have a single system to utilize for
COVID-19 vaccination. Future researchers may use the findings in this study to conduct further studies related to the
COVID-19 vaccination process. Other areas that may also be explored in the future include facility layout and design
of the vaccine centers, simulation studies, and workforce allocation modeling.
