Should you take a leftover vaccine? Should you pass up a vaccine if you think you don't need it as much as someone else does? We talk to bioethicists to get their answers on these questions and more.

Anna talks with Dr. Margaret Liu, one of the pioneers of gene-based vaccines, about vaccines that use mRNA to help us build immunity to COVID-19, including the Pfizer-BioNTech and Moderna vaccines. How is this method different from vaccines in the past, and what does the mRNA do once it gets inside our bodies?

There are so many questions about a COVID-19 vaccine that we didn't know where to begin. So we began with you! We took to the mailbag to find answers on vaccine availability, immunity, and more.

On the first day of Christmas, PODCAST-19 gave to me ... an interview with Dr. Fauci. Dr. Anthony Fauci stops by the pod to talk about post-vaccine life, the new variant of the virus in the U.K. and which celebrity he'd like to see vaccinated.

Data has been such a valuable commodity during the pandemic. Unfortunately, at times data has been in short supply, because US government agencies haven’t always undertaken national data collection efforts. So what happens when individuals citizens try to collect data themselves? We talk to Professor Emily Oster, who developed a national COVID-19 School Response Dashboard, to find out what she’s learned about COVID in schools, the implications of volunteers developing their own public health...

It feels like a cure for this pandemic may be in sight. But for many people, injecting a brand-new scientific discovery into their body won't sit well. So, how are scientists making sure that a COVID-19 vaccine won’t cause more damage than the disease? How do regulators decide what an acceptable side effect is? And what would happen if someone did have a serious reaction to the COVID vaccine after it was released? This week, we’re devoting our whole show to vaccine safety.

This week, Pfizer announced that its coronavirus vaccine may be more than 90 percent effective. Anna and FiveThirtyEight's senior science writer, Maggie Koerth, discuss what we know (and don't know) about about the vaccine.

We talk with FiveThirtyEight’s Nathaniel Rakich and Maggie Koerth about how states are trying to make it safe to vote in person this Election Day, and what you should keep in mind as you go to the polls.

Joe Biden says he can fight the pandemic better than President Trump. But is his plan really that different? And does it address what experts say needs to be improved upon?

After testing positive for COVID-19 last week, President Trump was given the three experimental drugs: an antiviral, monoclonal antibodies, and a steroid. On this week’s episode of PODCAST-19, we discuss what happens when all three drugs are combined and why the average American can't expect to receive the same treatment.

Today we learned that President Trump tested positive for COVID-19. In this special crossover episode, the crew from the FiveThirtyEight Politics podcast sat down with senior science writer and Podcast-19 contributor Maggie Koerth to talk about medical implications for the President, and the impact his diagnosis might have on the election.

As schools of all levels struggle to find a new way to educate students, universities, in particular, have had a difficult time navigating classes and campus life. On this week's show, we talk to a student navigating quarantined dorm life at the University of Wisconsin-Madison and a scientist who helped design a different approach to testing for the University of Illinois at Urbana-Champaign.

On this week’s episode of PODCAST-19, we discuss whether the FDA vaccine approval process can withstand political interference and how the agency can reassure the public that everything is working as it should.

We discuss the news that AstraZeneca's COVID-19 vaccine trial has been paused because of a severe side effect for one participant, and how temporarily halting a trial can sometimes mean the process is working as intended.

The U.S. doesn't want to participate in a global effort to find and distribute a vaccine for COVID-19. Anna talks with FiveThirtyEight senior science writer Maggie Koerth about what that decision might mean for the country and the world.

On this week's episode, we explore what it means that people can get reinfected with COVID-19, and how we can still develop immunity to the disease. We also explore why the approach to masks in the Netherlands is so much more lax than in parts of the U.S., even though Holland has done a better job of suppressing COVID-19.
