SARS-CoV-2 vaccine development

SARS-CoV-2 is a well-known viral strain that causes COVID-19. The disease became a pandemic in early 2020 and infected millions of people and killed hundreds of thousands of people worldwide. Vaccine development against the disease was accelerated with multiple collaborations among research institutions in order to shorten the duration that vaccine development normally takes. Prior coronavirus vaccines present a basis on which vaccines against the current strain can be developed with much speed and relative ease. Among the patented coronavirus vaccines, DNA-based vaccine had the most patents registered which must have clues to guide the efforts in the current works. This work presents some progress on COVID-19 vaccine development and also possible animal venom protein sources that can potentially be used in the pipeline. The future of COVID-19 vaccine is bright with the heightened collaborative efforts and data sharing opportunities that the pandemic has brought among researchers.
