The coronavirus disease 2019 (COVID-19) is a contagious viral infection of the respiratory system caused by SARS-coronavirus-2 (SARS-CoV-2). The outbreak of the disease was first reported in Wuhan, China in December 2019. The spread of COVID-19 is continuous and was declared a pandemic disease by the World Health Organization (WHO) on 11 March, 2020. As of 20 May 2020, more than 4.7 million people have contracted the disease and 318,789 people have died.
Vaccines save millions of lives each year. The development of safe and effective COVID-19 vaccines is a huge step forward in our global effort to end the pandemic and to get back to doing more of the things we enjoy with the people we love.
