Recent research on the vaccine has been tested to seek the right vaccine for COVID-19. This study is to focus on the current vaccine development against COVID-19 and to explore the potential vaccines’ characteristics that have been studied by the previous proven research findings. This review was done based on the research articles and reviews published until the end of April 2021 through established scientific search engines and related scientific platforms based on the inclusion criteria with its related keywords like coronavirus, SARS-CoV-2, COVID-19 Vaccine, clinical trials, and COVID-19 vaccine development. This review summarized a few vaccine candidates that have entered clinical trials and some supported evidence from Phase I until Phase III clinical trial studies that have been published and reported. In this review, 12 vaccine candidates have the potential to against SARS-CoV-2. Thus, their vaccine platform, characteristic as well as its efficacy studies have been discussed. Top Keywords Coronavirus, SARS-CoV-2, COVID-19 Vaccine, Clinical trials, COVID-19 Vaccine Development. Top |
