Astra Says 76% Efficacy; U.S. Cases Top 30 Million: Virus Update

U.S. cases surpassed 30 million, according to data from Johns Hopkins University. Brazil surpassed 300,000 deaths from Covid-19, the second-most in the world. Hong Kong suspended online bookings for BioNTech vaccines after reports of issues with the primary packaging material for vials in one batch.

AstraZeneca’s Covid-19 vaccine was 76% effective in a U.S. study, a slightly downgraded estimate based on the latest data collected from a contentious clinical trial, creating further uncertainty for the shots.

Boris Johnson warned that the U.K. may need tougher border measures “very soon” to prevent the arrival of Covid-19 variants from continental Europe that risk undermining the country’s vaccine rollout. The European Union and the U.K. signaled a thawing of relations over vaccine sharing.

Key Developments:

  • Global Tracker: Cases pass 124 million; deaths exceed 2.73 million
  • Vaccine Tracker: More than 486 million shots given worldwide
  • Global tourism looks shaky, with herd immunity a distant dream
  • Uncertain science behind Covid passports requires a leap of faith
  • Merkel’s virus crisis is changing the shape of Germany’s election
  • Biden uses Trump’s ‘America first’ vaccine plan to corner market
