U.K. will infect healthy volunteers in COVID-19 “challenge trial”

The trial will also help doctors and scientists understand how the immune system reacts to the virus and identify factors that affect how it is transmitted. hit its target of vaccinating 15 million people with their first dose. In that case, researchers expect that some volunteers will eventually be exposed to the virus naturally.Challenge trials, however, guarantee exposure in the hopes of speeding up results. They have been used in the past to study diseases like malaria, typhoid, cholera, norovirus and influenza. After the first trial, a small number of volunteers could be given vaccine candidates that have passed clinical trials, to identify which are most effective. and will help accelerate scientists’ knowledge of how coronavirus affects people and could eventually further the rapid development of vaccines.”

The controversial study is different from typical vaccine trials, in which participants are given a vaccine or placebo and then told to go about their everyday lives. “We expect these studies to offer unique insights into how the virus works and help us understand which promising vaccines offer the best chance of preventing the infection.”

England is set to become the first country in the world to intentionally infect healthy volunteers with COVID-19 in what’s known as a “human challenge study.” The country’s medical ethics body approved the trial Wednesday. 

Funded by the British government, the $47 million study will play a crucial role in continuing the development of effective coronavirus vaccines and treatments, officials said.The first-of-its-kind challenge study is expected to begin within the next month, involving up to 90 carefully selected, healthy volunteers aged 18-30.
