Rachel Feltman: For Scientific American’s Science Quickly, I’m Rachel Feltman. This is the final episode of our three-part series on bird flu.

(You can listen to episode one here and episode two here.)

On Wednesday we met scientists who are getting their hands dirty with dairy cows and poultry to better understand how H5N1 bird flu is spreading. Today we’ll take a look at efforts to create vaccines for H5N1—and learn why eggs are so critical to the vaccine-making process.

Our host today is Naeem Amarsy, a multimedia journalist based in New York City. Here’s Naeem now.
