WASHINGTON (AP) — Results from a U.S. trial of AstraZeneca's COVID-19 vaccine may have used "outdated information," U.S. federal health officials said early Tuesday.
The Data and Safety Monitoring Board said in a statement that it was concerned that AstraZeneca may have provided an incomplete view of the efficacy data.
