Oxford COVID-19 Vaccine Shows Promise

Early data shows vaccine under development by Oxford University and AstraZeneca triggers antibodies and the production of virus-fighting T-cells. NBC's Sarah Dallof reports.

(NBC News) Early data from human trials of a vaccine being developed by pharmaceutical company AstraZeneca and Oxford University indicate it induced two immune responses: The production of antibodies and production of T-cells which attack virus cells.
