Health Secretary Sajid Javid is set to give a major announcement tonight on whether mandatory vaccines for NHS staff will dropped.
The rule was set to be enforced from April, which meant if staff hadn't had their first dose by this Friday they would not be double vaccinated in time.
Ministers are thought to have u-turned on the policy amid fears it will lead to a major staffing crisis.
Downing Street said Boris Johnson and Mr Javid have been reflecting on the policy as it was introduced when the Delta variant was the dominant strain.
