COVID-19 vaccine refers to vaccines that can provide acquired immunity against SARS‑CoV‑2, the virus that causes coronavirus disease 2019 (COVID. 19). As of February 2021, 66 vaccines are in clinical research, with 17 in Phase I, 23 in Phase I–II, 6 in Phase II, and 20 in Phase III. The trial of four other vaccines has been ended.
In February 2020, the World Health Organization (WHO) stated that a vaccine for COVID-19 cannot be expected to be available in less than 18 months.
The Coalition for Epidemic Preparedness Innovations (CEPI), which is organizing a worldwide US$2 billion fund to rapidly develop vaccine candidates, indicated in April that 12 months Its vaccine may be available for emergency use in at least 2020 or as early as 2021.
On 4 May 2020, the WHO held a telethon (televised fundraising event) to raise US$8 billion from forty countries to support the rapid development of vaccines to prevent COVID-19 infection, as well as several vaccine candidates announced the deployment of an international “Solidarity Trial” Phase II-III clinical trial for the simultaneous evaluation.
