The COVID-19 pandemic is caused by SARS-CoV-2, which was first identified in December 2019 in Wuhan, China. The World Health Organization designated the outbreak a pandemic on March 11.
Countries across the world are racing to develop a vaccine to curtail the pandemic, with Russia becoming the first country to approve such a drug for distribution in August. However, some scientists and health experts have cast doubt on the safety and effectiveness of the Russian vaccine - dubbed Sputnik V - which has yet to undergo Phase 3 trials.
