Flu shot season is upon us.

Three years ago, STAT laid out some of the questions surrounding flu vaccination in an article you can find here. Lots of flu vaccine studies have been published in the interval — clearing up some of the questions we raised, adding to the confusion with others.

Given that a lot of you are either about to roll up a sleeve or are debating whether you should, we decided to revisit the issues we explored previously, based on new information. We’ll also raise a few more questions percolating in the world of influenza science.
