Hi folks. Thanks for listening to Patient Zero. This week, we're doing something a little different.

Instead of a full episode, you're getting one of several bonus episodes that up until now have only been available to donors of New Hampshire Public Radio.

We wanted you to hear this one for three reasons. One, because you deserve to know how awesome our bonus episodes

are. Two, because the topic addressed in this episode is one that a lot of people who haven't

donated have asked about. It's important. And three, because I needed a couple extra days to finish

the next full episodes. This show is a lot of work, and we're committed to doing the best and most thorough job

possible.

So thanks for listening, and if you dig this bonus episode, check out the others by making a

donation of $20.

There's a link in the show notes.

why can my dog be vaccinated against Lyme disease, but I can't?

Why can't they come up with a human version?

And of course the answer is, we have a human version, or we had a human version.

Megan May teaches about infectious disease at the University of New England, and she's here

to tell us the story of Limericks.

Limericks is the vaccine, developed by the giant multinational pharmaceutical company,

Glaxo-SmithKline, that was was released in 1998 but pulled from the market in 2002.
