RE: ACTIV-3 (in-patient) trial loses 2 out of 4 candidates4 Mar 2021 18:48
Scientists have identified 16 cases of another new variant of coronavirus in the UK.
Public Health England has designated it as a "variant under investigation", meaning it is on its watch list but not one PHE is immediately concerned about.
It does have a mutation in common with the South Africa and Brazil variants, however.
That genetic change, E484K, may help the virus evade immune attack.
It's not unexpected that variants are appearing or that they will continue to change - all viruses mutate as they make new copies of themselves to spread and thrive.
