      What do we know about the new mutations?

      An initial analysis of the new variant has been published and identifies 17 potentially important alterations.

      There have been changes to the spike protein – this is the key the virus uses to unlock the doorway to our body’s cells.

      One mutation called N501Y alters the most important part of the spike, known as the “receptor-binding domain”.

      This is where the spike makes first contact with the surface of our body’s cells. Any changes that make it easier for the virus to get inside are likely to give it an edge.

      “It looks and smells like an important adaptation,” said Prof Loman.

      The other mutation – a H69/V70 deletion, in which a small part of the spike is removed – has emerged several times before, including famously in infected mink.

      Work by Prof Ravi Gupta at the University of Cambridge has suggested this mutation increases infectivity two-fold in lab experiments.

      Studies by the same group suggest the deletion makes antibodies from the blood of survivors less effective at attacking the virus.

      Prof Gupta told me: “It is rapidly increasing, that’s what’s worried government, we are worried, most scientists are worried.”

      And doctors have said the current vaccines are probably effective with that strand. No need to panic.

      Do you think that they send unsolicited spike pics to eachother?
