Pfizer Says Its Coronavirus Vaccine is 95% Effective

VOA News

   The pharmaceutical company Pfizer said Wednesday that its coronavirus
   vaccine is 95% effective and caused no serious side effects as it plans
   to seek federal approval for the vaccine's emergency use.

   Pfizer disclosed the results after a final analysis of the vaccine's
   Phase 3 trial, which also revealed it protects older people most at
   risk of dying from COVID-19, the disease caused by the coronavirus.

   The American pharmaceutical giant's announcement came a week after it
   first revealed promising preliminary findings, and days before it plans
   to formally ask the federal government to approve the vaccine for
   emergency use.
