An outbreak of meningitis that has killed a university student and a sixth former is unprecedented, health chiefs have said.
The number of confirmed cases of invasive meningitis in the Canterbury area stands at 15, with a targeted vaccination programme announced at the University of Kent.
Two people have died - a 21-year-old university student and Juliette, a sixth form pupil at Queen Elizabeth's Grammar School in Faversham.
Susan Hopkins, chief executive of the UK Health Security Agency (UKHSA), said there was an "explosive nature" to the outbreak, while deputy chief medical officer Dr Thomas Waite said it was the quickest growing outbreak he had seen in his career.
Earlier, Health Secretary Wes Streeting described it as an unprecedented outbreak and a "rapidly developing situation".
