The health secretary has said he is not concerned about an NHS warning that a 'significant reduction' of vaccine supplies could leave people under the age of 50 waiting an extra month for their first shot. 
Playing down the importance of what he described as a 'normal operational letter', Matt Hancock said the government's plan to offer every adult a vaccine by the end of July had not changed. 'Vaccine supply is always lumpy,' he said. 'These supply schedules have moved up and down throughout this whole rollout –it's absolutely par for the course.'
