I'm more than a little suspicious of a bunch of Computer Science folks running some data through their machine learning tool and then trying to tell the vaccine makers they should change their recipe because of it. Even assuming their data is correct, the variation in effectiveness is 10% and for people in their worst case scenario group it would still be one of the most effective vaccines every created.
