Researchers at Oxford University published a study in The Lancet about human trials of a potential coronavirus vaccine they developed and began testing in April 2020. The research was funded by a £20 million ($24 million) grant from the UK's National Health Service. The vaccine was made from a weakened version of a common cold virus that causes infections in chimpanzees. It was modified to make it impossible to grow in humans. Proteins from the Covid-19 virus's outer coat were then added. "We hoped the body would recognize and develop an immune response to the COVID-19 protein that will help stop the SARS-CoV-2 virus from entering human cells and therefore prevent infection," the University said. In the trial 1,068 volunteers were recruited. They were assigned by a flip of a coin to either be injected with the coronavirus vaccine or to receive a control - a widely available meningitis vaccine. Volunteers, who lived in a variety of locations around the U.K., were then followed for 6 months. The researchers performed laboratory tests each week to determine if the volunteers had contracted COVID-19 (the disease caused by the coronavirus). The following are the results of the study: Number of people Number of cases Number of of COVID-19 COVID-19 deaths 527 53 (10.0%) 15 (2.8%) People who received the coronavirus vaccine People who received the meningitis vaccine 541 97 (17.9%) 31 (5.7%) "Mortality rate is based on the number of people in the study group. Mortality rate can be calculated based on population total or number of cases. Question: Vaccines have been used in the past to prevent disease symptoms in patients.
