They will be administered tiny droplets of the virus into their nostrils as part of a plan authorised by British regulators Wednesday to deliberately infect unvaccinated volunteers with the coronavirus. In the past, scientists have deliberately exposed volunteers to diseases like typhoid and cholera to test vaccines. But infected people could be cured of those diseases; COVID-19 has no known cure, putting the scientists in charge of the British study in largely uncharted ethical territory. To ensure that participants do not become seriously ill, the British study will be restricted to healthy volunteers, in an 18 to 30 age range. Now that several vaccines have been authorised, the goals of this human challenge trial are somewhat different.
