If you read in the coronavirus main thread there are new Danish mink strains which could/will likely render these vaccine efforts null and void, causing them to start over...I wouldn't get too excited over this news and I personally have some reservations over these quickened vaccine efforts...
Deadly Wuhan Coronavirus
...
There's always that possibility if you are of a bent to look on the dark side of what is supposed to be a joyous announcement... personally I believe that until proven otherwise, this is the best news for a long time, and am allowing myself to bask in it for a while mate.
MINK MUTATED COVID-19
A mutated version of coronavirus caught from mink might render Pfizer's vaccine less effective than its touted 90 per cent figure.
Scientists believe the virus jumped from farm workers to mink in the summer before being passed back to humans.
As it crossed between species, a mutation occurred on its 'spike' protein, which it uses to enter human cells.
This mutation of the protein appears to make the strain more resistant to antibodies, disease-fighting proteins made and stored by the immune system.
Pfizer's jab trains the body to produce a wave of these antibodies by exposing it to a weakened version of Covid-19 that doesn't cause illness.
But if the new variant of Covid-19 becomes the prevailing strain then there are fears the vaccine could be less effective.
Ian Jones, a virologist from the University of Reading, told MailOnline the possibility of the mink strain being able to duck the body's antibody response was a 'formal possibility'.
He said: 'In theory, the mink form, which has mutations in the spike protein, could then evade the immune response generated to the vaccines currently in development and form Covid-19-2.
'There are a lot of reasons why this would not happen easily, but it is a formal possibility which is why the mass cull has taken place."
