German health minister: 'Certainly' a coronavirus vaccine 'in the next year'

Germany's health minister says there will 'certainly' be a coronavirus vaccine 'in the next year.' Jens Spahn said he was 'optimistic' that a vaccine would be developed in the coming months. He did not specify which vaccine he believed would prove safe and effective and added that it was not yet possible to know how long any such treatment would offer immunity against Covid-19 for. More than 100 vaccines around the world are currently in development.
