CoVid19 Mutations Not Making Virus More Contagious

  Vidcast:  https://youtu.be/TBH-PE9HL7Q   CoVid19 virus has been mutating, but the mutations don’t make the virus more transmissible.   Virologists at University College London nearly 16,000 worldwide genetic variations of CoVid.   Their data show none of the 31 recurrent mutations are associated with an increase in viral spread person to person locally or between regions.  In fact, 3 of the mutations were significantly associated with diminished transmission.  These involved changes in the spike protein, and it is this protein that attaches to human cells and permits viral entry.   It is good news that the inevitable CoVid mutations don’t appear to make the virus more vicious.  Whether mutations will interfere with vaccine production is another matter.   https://www.biorxiv.org/content/10.1101/2020.05.21.108506v1.full.pdf   #covid #mutation #transmissibility #vaccine
