The leaders of Britain and Italy have warned that the world cannot wait for a coronavirus vaccine.<br/> Italian Prime Minister Giuseppe Conte and UK Prime Minister Boris Johnson said citizens would have to adapt to living with the virus.<br/> Mr Conte is allowing restaurants, bars and beaches to open from Monday, and for church services to resume and shops reopen. "We are facing a calculated risk in the awareness that the epidemiological curve could go back up," he said.<br/> "We are confronting this risk and we need to accept it, otherwise we would never be able to relaunch." Mr Conte said Italy could "not afford" to wait until a vaccine was developed.<br/> Mr Johnson wrote in the<em> Mail on Sunday</em> newspaper: "I said we would throw everything we could at finding a vaccine. "There remains a very long way to go and I must be frank that a vaccine might not come to fruition."<br/> Mr Johnson was last month admitted to intensive care with Covid-19. Professional soccer matches in Germany's Bundesliga resumed over the weekend and were keenly watched by the rest of the football world.<br/> The games took place in empty stadiums, and players were warned not to spit, shake hands or hug each other to celebrate goals.
