I think it will be possible but I don't think it will be as easy or as quick as some people think it will be. Even if they come up with a viable vaccine it still has to be tested, then trialled, then it has to be made available and distributed. Each one of those steps takes time and money, I know there are reports that countries are making plenty of money available but it will still take years to become freely available. We can't properly test or supply PPE so why do people think we can create, trial, manufacture and distribute a vaccine by the end of the year or sooner?
