A COVID-19 vaccine is a hypothetical vaccine against coronavirus disease 2019 (COVID-19). Although no vaccine exists yet, there are multiple attempts in progress to develop such a vaccine. In late February 2020, the World Health Organization (WHO) said it did not expect a vaccine against SARS-CoV-2, the causative virus, to become available in less than 18 months.[1] By early March 2020, some 30 vaccine candidates were in development.
