In late February 2020, the World Health Organization (WHO) said it did not expect a vaccine against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative virus, to become available in less than 18 months. The Coalition for Epidemic Preparedness Innovations (CEPI)which is organizing a billion worldwide fund for fast investment and creation of vaccine candidatesindicated in April that a vaccine may be available under emergency use protocols in less than 12 months or by early 2021. On 4May 2020, the WHO organized a telethon (fundraising event broadcasted via televisions) to raise billion from forty countries to support rapid development of vaccines to prevent COVID-19 infections and deaths. The United States government started Operation Warp Speed to develop a vaccine by January 2021.
