An offshoot of the Delta coronavirus variant which is slowly spreading throughout the UK is expected to be dominant within a matter of months, experts believe.
Known as AY.4.2, the sub-variant is thought to be at least 10 cent more transmissible than its predecessor, with analysis underway to determine what accounts for its increased infectiousness.
The UK Health Security Agency (UKHSA) has said that early tests do not suggest that AY.4.2, which has been labelled a ‘Variant Under Investigation’, has acquired the ability to evade immunity generated by infection or injection.
