In some cases, they do not. But they work often enough and to a high enough degree of efficacy that we still should bother.

Now, to bring this back around to being on-topic to the thread it's in, whether or not vaccines "work" is actually irrelevant. Either they do work and therefore stop the spread, or they don't work and they therefore don't stop the spread. A vaccine can not work without doing its job.
