AstraZeneca's Covid-19 vaccine showed 79% efficacy against symptomatic disease and 100% efficacy against severe disease and hospitalization in a new, US-based clinical trial, the company said Monday.
The findings from the new Phase 3 trial, which included more than 32,000 participants, may boost confidence in the vaccine, which was originally developed by the University of Oxford. The trial showed that the vaccine was well-tolerated and identified no safety concerns, the company said. An independent committee "found no increased risk of thrombosis or events characterized by thrombosis among the 21,583 participants receiving at least one dose of the vaccine," according to AstraZeneca.
A federal judge on Friday blocked President Donald Trump’s administration from enforcing most of his executive order on elections against the vote-by-mail states Washington and Oregon, in the latest blow to Trump’s efforts to require documentary proof of citizenship to vote and to require that all ballots be received by Election Day.

A Border Patrol agent shot two people in Portland, Oregon, during a traffic stop after authorities said they were associated with a Venezuelan gang, another incident in a string of confrontations with federal authorities that have left Americans frustrated with immigration enforcement during the Trump administration.
