LONDON (Reuters) - British Prime Minister Boris Johnson said on Monday people needed to self-isolate more if potentially exposed to COVID-19 than they currently were doing.

Announcing a new lockdown for England in parliament, Johnson also said there was a real prospect of a vaccine for the disease in the first quarter of 2021.
