165: Covid-19 vaccines in development

Be in no doubt about it - the guaranteed way for us to get out of the Covid-19 pandemic is a safe and highly efficacious vaccine. We even know exactly what success will look like. The FDA in the USA is the federal agency in charge of protecting and promoting public health there. It has said that a vaccine for Covid-19 needs to be safe, 70pc effective and be given to 70pc of the population if we are to eradicate Covid-19. How likely is this prospect and when will it happen?

You can't fault the world for want of trying. There are more than 165 different vaccines being developed, with 27 of them reaching human trials. This is more than were ever tried for malaria, a disease that still kills at least 400,000 people per year, with more than 90pc of those deaths occurring in Africa. Because it's not a major problem for wealthy countries, maybe that's why there has been less effort against malaria.
