BackgroundThe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019 and spread globally, prompting an international effort to accelerate development of a vaccine. SARS-CoV-2 transmit among the people fast and infected thousands of people daily around the world. Because of rapid transmission of SARS-CoV-2 among the people, there is an urgent need to prevent people from infection or hospitalization and control the disease.MethodsWe will search electronic databases such as PubMed, Web of Science, Cochrane (CENTRAL), Scopus, Google scholar, the key journals (vaccine and vaccines). Moreover, trial registry including clinicalTrials.gov, WHO ICTRP, and ISRCTN will be searched. We will only select all clinical trial studies in any phases of evaluation (i.e. phase I, II, II, IV). For anti-spike glycoprotein antibody (IgG) response and neutralizing antibody response, we will report Ratio of Geometric Mean (RoGM), Ratio of Mean (RoM) or standardized mean difference (SMD) depends on type of articles.DiscussionVarious vaccine platforms have been developed to increase the resistance to the SARS-CoV2 virus and reduce hospitalization and mortality rates. The comprehensive data gathering and analysis of results will guide scientists about the best available evidence. Moreover, the current study results may indicate which of the vaccine platforms are more effective and safe for COVID-19.
