Delta subvariant, known as AY.4.2, is expanding and accounts for approximately 6% of all sequences generated in the UK.
New Delta Strain Subvariant Spreading Through United Kingdom
Oxford Vaccine Group chief Andrew Pollard said on Wednesday that a Delta subvariant that is spreading in England is being monitored but is unlikely to alter the COVID-19 picture.
The subvariant, known as AY.4.2 in the UK, is expanding and accounts for approximately 6% of all sequences generated, according to the UK Health Security Agency, although it has not been labelled as “under investigation" or a “variant of concern."
Pollard told BBC radio that “Discovery of new variants is of course important to monitor, but it doesn’t indicate that that new variant is going to be the next one to replace Delta.”

“Indeed even if it does, Delta is incredibly good at transmitting in a vaccinated population and a new one may be a bit better but it’s unlikely to change the picture dramatically from where we are today."
