The Sunday Times reported that a source involved in the search for a vaccine told ministers: “There is around a one in three chance that we get a vaccine at all.”
The warning comes as Boris Johnson is battling to reopen schools in September.
The Prime Minister is under pressure to shut pubs, restaurants and shops ahead of schools in the event of coronavirus flare-ups.
