Healthy volunteers will be deliberately infected with coronavirus as part of U.K. study

The UK government has agreed to help fund a ‘challenge’ trial in which participants are intentionally exposed to COVID-19, in hopes to gain quicker and more relevant information on the efficacy of vaccines. The first step is known as a characterization study, where researchers determine the lowest level of exposure necessary in order to cause symptom onset in participants between the ages of 18 and 30. This is an important step in helping researchers understand how the human body reacts to a dose of the virus. From there another pool of participants will be given a vaccine candidate and exposed to COVID-19. The characterization study will begin in early 2021.
