What Would a Second Generation Vaxcines Really Look Like?

Ell helen, thanks is always for joining us. So in your story, you quoted the university of minnesotas michael ulstrhom, saying that none of the vaccines on the horizon have the characteristics that we actually need for the future. So what would one of those vaccines actually look like?
