Until you actually have efficacy data on a vaccine, it is impossible to say whether a vaccine will work in humans or not. That’s true for the vaccine licensed in China as well; without efficacy data I wouldn’t think about having that vaccine. On whether the sense of security around vaccines still in the pipeline is misplacedThe first thing is, is the vaccine going to work? Now will multinationals, will the successful makers of vaccines provide vaccines to the global allocation mechanism? We have not so far had an RNA vaccine or a DNA vaccine licensed.
