Britain Seeks Vaccine Changes to Address COVID-19 Variants

VOA News

   Britain's health minister said Tuesday the government there is
   considering modifications to existing COVID-19 vaccines to address
   variant strains of the coronavirus.
   Health Minister Matt Hancock made the announcement in parliament, a day
   after health officials said they has discovered 105 cases of a COVID-19
   variant first identified in South Africa, 11 cases of which had no
   apparent links to international travel. The nation also continues to
   grapple with another variant, first identified in Britain.
   The variants have generally not been shown to be more severe than the
   original virus but appear to be more easily transmissible.
