[Antibodies and antigens and lymphocytes, oh my! What exactly do these microscopic medical marvels have to do with vaccines?. Imagine courtesy of the Encyclopaedia Britannica.]

In the second part of our series on vaccines, I’ll be giving a brief overview of how the immune system works and how vaccines help train it to fight disease! Keep in mind that this information has been simplified somewhat for easier understanding (on both my part and yours, I’m certainly no immunologist!); the immune system is a wildly complex and intense part of any living being! But as primers go, this should help further your understanding 🙂 Missed the first part of this series? Check out Part One for a basic vaccine overview.
