    Show one shred of data backed evidence that vaccines do not provide protection against disease for a period of time after vaccination.

    So what if we have to get revaccinated periodically? It does not mean that vaccines don't work, it simply means that there are normal human variances in our immune response, and that some people don't retain as strong a response as needed after several years. Seriously, WHAT IS THE BIG DEAL ABOUT REQUIRING PERIODIC REVACCINATION?
