Prime Minister Boris Johnson is under pressure from his MPs to give a timetable to ease lockdown measures.
The rapid rollout of vaccines has led to calls for the PM to re-open schools by March 8th.
Also, to start to relax the restrictions on people being out and about.
However, the Government’s Scientific Advisory Group for Emergencies (Sage) warns it was not sensible to set out a roadmap now.
Scientists say it could damage the good work done with the vaccine if the stay-at-home restrictions were eased.
