The efficiency of the proposed vaccine is then analysed in both test tubes and on animals. Identifying relevant antigens is one of the major steps, with findings used to create an initial vaccine concept. The first stage of vaccine development is pre-clinical development, which is carried out in laboratories and usually involves animal testing. The process involves several phases and can often require years of research and development, though in the case of COVID-19 scientists are hopeful a vaccine can be fast tracked. While nothing is guaranteed, experts are hopeful a vaccine for COVID-19 can be developed. With global cases of the coronavirus disease edging towards three million and more than 200,000 lives claimed, fast tracking a vaccination is front of mind for laboratories around the world.
