[ Should researchers shelve plans to deliberately infect people with the coronavirus? ]

U.K. scientists are moving ahead with plans to infect volunteers with the virus that causes COVID-19. Such experiments have been done with other pathogens, including flu viruses (pictured here).

Science’s COVID-19 reporting is supported by the Pulitzer Center and the Heising-Simons Foundation.

In the early days of the COVID-19 pandemic, tens of thousands of young volunteers offered to risk their health by letting scientists intentionally infect them with the pandemic coronavirus, hoping to speed the hunt for a vaccine or treatment. Several research groups announced plans to run these so-called human challenge trials, even as some scientists questioned whether they could be conducted ethically.

U.K. Plans ‘Challenge Trials,’ Which Will Intentionally Give People COVID

On Oct. 20, researchers at the Imperial College of London announced plans for the first human challenge study of COVID-19, which involves deliberately infecting volunteers with the virus that causes the disease, in order to test the effectiveness of vaccines.

The strategy is controversial, as researchers have to weigh the risks of infection against the benefits of learning how well the various vaccine candidates can fight that infection. The strongest argument in favor of the studies has to do with time. If cases of COVID-19 are waning, then the likelihood that people who are vaccinated would get exposed to and potentially infected with the virus naturally declines as well, and it takes researchers longer to accumulate enough data to tell if a vaccine is effective or not. By intentionally exposing people to the virus after they have been vaccinated, researchers can shrink this timeline significantly.

Early Data Show Moderna’s Coronavirus Vaccine Is 94.5% Effective

Both companies plan to apply within weeks to the Food and Drug Administration for emergency authorization to begin vaccinating the public. Officials said the two companies could produce enough vaccine for a little more than 20 million people in the United States by sometime in December, with the first doses going to people with the highest risk, like health care workers, emergency medical workers and frail residents of nursing homes.

But a vaccine that would be widely available to the public is still months away, while the need for one is becoming increasingly urgent.

Despite those sobering measures, the stock market rallied on Monday, fueled by Moderna’s news. But businesses and others braced for what could be a bleak holiday season with Covid’s grip on the nation’s citizens and its economy.

UK to infect healthy volunteers in vaccine research trial

While other people are wearing masks and staying home to avoid the disease, the 22-year-old Londoner has volunteered to contract the new coronavirus as part of a controversial study that hopes to speed development of a vaccine.

Imperial College London and a group of researchers said Tuesday that they are preparing to infect 90 healthy young volunteers with the virus, becoming the first to announce plans to use the technique to study COVID-19 and potentially speed up development of a vaccine that could help end the pandemic.

‘Deliberately infecting volunteers with a known human pathogen is never undertaken lightly,’ said Professor Peter Openshaw, co-investigator on the study. ‘However, such studies are enormously informative about a disease, even one so well studied as COVID-19.’

UK government signs contract for first coronavirus human challenge studies

The UK government has signed a contract for the first human challenge studies for the novel coronavirus, in which healthy volunteers are deliberately infected with the virus in a controlled setting, and some receive an experimental vaccine.

For the current Covid-19 vaccine candidates that are in Phase 3 ‘ the final stage of testing ‘ tens of thousands of volunteers are given an experimental vaccine and then released to live their everyday lives; researchers assume that a certain percentage of them will be exposed to the virus naturally.
