The discovery of the genotype and phenotype of SARS-CoV-2 boosted the global efforts for the development of treatment options and vaccines for the COVID-19. As the transmission of the virus is rapid, to protect the global population, the development of an effective vaccine against the virus is very essential. The current review highlights the various platforms and technologies used globally for the development of the vaccine and also focuses on the current status of the vaccine candidates under development by organizations to combat the global threat of COVID-19 pandemic.
