There's a new Vaccines course on Coursera, starting this coming week. If you join now (it's free) you can see the first week's lectures. I've heard this is a good course.

There's also a new Facebook page called The Vaccine Page, designed specifically to keep a neutral tone and answer tough questions about vaccines.
