There’s been a lot of blogging about vaccines lately:

• Mark Meier at Science Progress explains how a cocaine-addiction vaccine was developed, and what questions and hurdles it still faces.
• Jacob Goldstein at WSJ’s Health Blog explains what this year’s mismatched flu vaccine means for next year’s production (also see Effect Measure on this year’s flu season).
• DrugMonkey and Mike Dunford at the Questionable Authority are livid about the parents whose antivaccination stance led to measles for their three children and several others.
• Abel Pharmboy at Terra Sigillata focuses on the dangerous antivaccinationist movement and what American Association of Pediatrics is doing to combat it (although it’s his vasectomy liveblogging that’s drawing most of his visitors).
