Summary

Learn about how we make vaccines to fight viruses like the coronavirus, with help from Julia Schaletzky, Executive Director of the Center for Emerging and Neglected Diseases at UC Berkeley. You’ll also learn about the weird history behind why we call steak “beef” and not “cow.”

0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com.
0:06.5	I'm Cody Gough. And I'm Ashley Hamer.
0:08.6	Today you learn about how we make vaccines to fight viruses like COVID-19, with help from Julia Shaletzky,
0:14.8	executive director of the Center for Emerging and Neglected Diseases at UC Berkeley.
0:19.4	You'll also learn about the weird history behind why we call steak beef and not cow.
0:24.0	Let's satisfy some curiosity.
0:26.0	How do viruses infect us and how can vaccines help?
0:30.0	We thought now might be a good time to tackle the science on this podcast,
0:33.4	since pretty much everyone on the planet is hoping for a COVID-19 vaccine right about now.
0:38.8	So we got in touch with Dr. Julius Schletzky. She's the Executive Director of the Center for Emerging and Neglected Diseases
0:45.2	the Drug Discovery Center and the Immunotherapy and Vaccine Research Institute at UC Berkeley.
0:51.2	Here's Dr Schletzky on how coronavirus infects us in the first place.
0:55.3	The way viruses infect the body is very interesting because most of them can't just get
1:01.1	into the cell so I'm just going to use an analogy here.
1:05.0	It's like if a guest wants to enter your house and the guest is the virus and the house is your body or your cell,
1:11.0	the virus needs a key for the door to even get in, so it can't just walk through the wall.
1:17.2	It needs to have a key, and the key needs to fit in the lock and then the door opens.
1:22.0	He gets in. So for coronavirus the key is this spike
1:26.3	protein that's outside on the virus and it fits right onto a receptor called the H2
1:32.3	receptor that is expressed on human cells and codes the outside of human
1:37.6	cells and so what happens is the key from the virus interacts with the lock from the human cell and then the door opens and the
1:45.1	virus basically walks into your cell and then it's going to use everything you
