WHO to Review AstraZeneca Vaccine after South Africa Halts Vaccinations

VOA News

   The World Health Organization (WHO) said Monday it is reviewing the
   AstraZeneca COVID-19 vaccine in light of a South African study
   indicating the drug offers minimal protection against the new South
   Africa variant of the virus.

   The study, conducted by the University of the Witwatersrand, prompted
   the South African government to temporarily halt its use of the
   vaccine.

   At WHO's usual Monday briefing at its headquarters in Geneva, WHO
   Director-General Tedros Adhanom Ghebreyesus called the news concerning
   but noted what he called "some important caveats" to that development.
