    How COVID-19 human challenge trials work -- and why I volunteered | Sophie Rose

    How COVID-19 human challenge trials work -- and why I volunteered | Sophie Rose

    In April 2020, epidemiologist-in-training Sophie Rose volunteered to be infected with the virus that causes COVID-19. As a young, healthy adult, she's offering to take part in a human challenge trial, a study where participants are intentionally exposed to SARS-CoV-2 to test vaccines and gather critical data. Explaining how challenge trials could speed up the development of effective vaccines, Rose shares why volunteering was the right decision for her.

    How the US medical community fails Black mothers | Wanda Irving

    How the US medical community fails Black mothers | Wanda Irving

    In the US, Black women are nearly 300 percent more likely to die as a result of childbirth than white women. Sharing appalling statistics on maternal mortality as well as her own tragic story of loss, Wanda Irving explains how racism and bias in health care minimizes and dismisses Black women's pain -- and makes a personal plea for leaders in the medical community to take steps toward reform.

    Can light stop the coronavirus? | David Brenner

    Can light stop the coronavirus? | David Brenner

    Far-UVC light is a type of ultraviolet light that kills microbes and viruses and, crucially, seems to be safe to use around humans. Radiation scientist David Brenner describes how we could use this light to stop the spread of SARS-CoV-2, the virus responsible for COVID-19, in hospitals, nursing homes, trains and other public indoor spaces -- paving the way for a potentially game-changing tool in the fight against the coronavirus pandemic. (This virtual conversation, hosted by TED science curator David Biello, was recorded July 7, 2020.)

    The case to infect volunteers with COVID-19 to accelerate vaccine testing | Nir Eyal

    The case to infect volunteers with COVID-19 to accelerate vaccine testing | Nir Eyal

    Conventional vaccine testing is a slow, years-long process. As thousands of people continue to die each day from COVID-19, bioethicist Nir Eyal proposes a radical idea that could dramatically accelerate the vaccine development timeline: "human challenge trials," in which scientists would deliberately expose volunteers to the virus to more quickly determine a vaccine's efficacy. (This virtual conversation, hosted by head of TED Chris Anderson, was recorded June 15, 2020.)

    The new science of personalized vaccines | Ofer Levy

    The new science of personalized vaccines | Ofer Levy

    At the intersection of precision medicine and vaccinology lies a revolutionary scientific pursuit: personalized vaccines. Infectious disease specialist Ofer Levy introduces this promising medical approach, in which tailored inoculations will enable effective immunization of the most vulnerable among us, including the young and elderly, and shares how we're now venturing into a new era of sustaining and supporting human life. (This talk contains graphic medical imagery.)
