Our first crossover episode this season with Dr. Matt Candeias of In Defense of Plants stars everyone’s favorite irritating plant-originated substance: urushiol! Join us for a light-hearted deep dive into urushiol, aka the stuff in poison ivy that makes you soooo itchy/burny/scratchy. Have you ever wondered why popping a benadryl doesn’t relieve those oozing, raised welts all over your gardening arms? Or whether a poison ivy rash has ever been used as evidence in a murder case? Or why poison ivy and other plants produce this substance in the first place? Don’t worry, just like a poison ivy rash after a summer gardening sesh, we’ve got you covered.

We’re back with another episode in our Anatomy of a Pandemic series on COVID-19. This time, our subject matter is the one everyone has been waiting for: vaccines. In this episode, with the help of two amazing guests, we attempt to answer all of your burning questions about the new vaccines for the virus that causes COVID-19. We walk you through the ins and outs of the technology behind these vaccines, the safety and regulation steps required for their approval, and some of the logistical challenges involved in their distribution. For this info-packed episode, we were so fortunate to be joined by Dr. Maria Sundaram (interview recorded Dec 14, 2020), postdoctoral fellow at the University of Toronto Center for Vaccine Preventable Diseases and fellow at ICES and Dr. Orin Levine (interview recorded Nov 24, 2020), Director of Vaccine Delivery at the Bill and Melinda Gates Foundation. As always, we wrap up the episode by discussing the top five things we learned from our experts. If at the end of this interview, your curiosity about vaccines is not quite satisfied, check out the COVID-19 Vaccine Tracker website, which is an incredible resource for pretty much anything you could ever want to know about these vaccines.To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: Can you break down what the three potentially successful COVID-19 vaccines are and how each of them work? What are in these vaccines? What are the ingredients and what do they do? There has been some misunderstanding that these vaccines have the potential to give you COVID-19. Can you explain why that isn’t possible? Why are people being advised to wear a mask even after getting vaccinated? What does the timeline look like for these vaccines until we can go to the doctor or pharmacy and get one? Is it a valid concern that this vaccine was developed so rapidly? And could you walk us through some of the steps being taken to ensure safety and efficacy of a vaccine? Can you talk about what emergency use authorization means and whether we’ve seen this before and under what circumstances? Why should people be no more scared of this vaccine than the usual vaccines, like MMR and seasonal influenza? How likely is it that additional side effects we haven’t yet seen or long-term side effects will emerge later on? What do we know about the risk of vaccine-induced antibody-dependent enhancement with this vaccine? What do we know so far about the efficacy of these vaccines? Can you walk us through efficacy vs effectiveness in terms of vaccines? What do we know so far about how long immunity is expected to last from the various vaccines that are close to completion? What are some of the issues with clinical trials in vaccine development in terms of getting a representative subsection of the population and what does this mean for who may be able to get a vaccine once one is ready? Why do you still need to get vaccinated even if you’ve already had COVID-19? For our listeners who may know someone who is hesitant to receive the vaccine, what advice or reassurance can you give them that choosing to get one of these vaccines is a better option than taking your chances with COVID-19? What are the biggest hurdles to vaccine distribution here in the US? What are the biggest hurdles in terms of global distribution of the vaccine? And what is being done to address some of these challenges in vaccine access? We’ve heard about some countries pre-purchasing large stocks of vaccines, how may that affect the global availability especially in lower income countries? How might the availability of several different successful COVID-19 vaccines affect how different countries build their vaccine supply or distribution chain?  Could you talk about how skepticism surrounding vaccines plays into not only vaccine development but administration, and what can be done to rebuild trust in those communities? How do you think this pandemic will change the way that we view either emerging infectious diseases or vaccines in the future? Learn more about your ad choices. Visit megaphone.fm/adchoices

The neglected tropical disease known as leishmaniasis is really more of a collection of diseases caused by a variety of parasites transmitted through the bite of a diversity of sandfly species. Sounds a bit complicated? You’re not wrong. But have no fear. Because in this episode, we walk you through the ins and outs of leishmaniasis. From the biology of visceral vs cutaneous vs mucocutaneous leishmaniasis to the archaeological and modern history of these parasites, we give you the basics on one of the most globally prevalent parasitic infections.

That’s right, we are rebooting our Anatomy of a Pandemic series in which we cover various aspects of the COVID-19 pandemic that has held the world in its grip since early 2020. Since our first episodes in the series dropped in March of this year, we have learned quite a lot about the SARS-CoV-2 virus, the disease it causes, patterns in its transmission, and of course, how we can best control it. In our first episode back, we focus on this last facet by exploring what we now know about policies and practices that work best to slow the spread of this virus and dive into some of the nuance surrounding masks, infection hot spots, and traveling. For this episode, we were so delighted to chat with Dr. Saskia Popescu, infectious disease epidemiologist and infection preventionist and Assistant Professor of Biodefense at George Mason University (interview recorded December 4, 2020) (Twitter: @SaskiaPopescu). As always, we wrap up the episode by discussing the top five things we learned from our expert. To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: What have we seen so far in terms of regional or statewide control policies or practices that seem to best work for infection control? How might something like a nationwide mask mandate or even just fact-based, rational messaging have changed the course of this pandemic in the US? Can you highlight some of the patterns in the policies or practices of the countries where COVID-19 has been pretty well managed, in your opinion? Basically, what are other countries doing better than we are? Which individual behaviors or practices have been shown to be the most effective for virus control? Can you break down some of the different types of masks and explain which types of masks seem to be doing a pretty great job of slowing transmission and which ones may not be as effective? Our knowledge of where transmission is most likely to occur has become more nuanced as the pandemic has continued. How do things like grocery store visits and outdoor runs compare to indoor dining or working out in a gym? What are we seeing as hot spots of infection and what are safer than we previously thought? Although we know much more now than we did at the beginning of this pandemic, the fundamentals of the virus’s transmission and the ways we can control it haven’t really changed. So where is this surge of cases coming from? Do you think the lockdowns or increased restrictions being put into place in some high prevalence locations will have the same effect in flattening this third wave as they seemed to earlier in this pandemic? Do you think we’ll see a reduction in seasonal respiratory infections overall due to the mask wearing, increased handwashing, and social distancing people are practicing? What are the steps people can take to be as safe as possible if they are committed to traveling during this holiday season? What would you say to those experiencing COVID fatigue?

Your long wait is finally over - the season four premiere of This Podcast Will Kill You has arrived! And to mark the special occasion, we’re taking on a topic that is both classic TPWKY material as well as enormously relevant to current discussions in public health. Typhoid fever has been the cause of untold death and devastation throughout human history, and despite our advancements in both treatment and prevention of the disease, it continues to wreak havoc on millions of people around the world every year. This week, we take a trip through the terror of typhoid, starting by tracing the journey this bacterium makes through your body before taking a look at the long history of typhoid in human populations. And what story of typhoid would be complete without Typhoid Mary? We examine the plight of Mary Mallon in the context of today’s COVID-19 pandemic and discuss the tension that often arises between individual and community rights in matters of public health. Finally, we wrap things up with a look at the current status of typhoid fever around the world (spoilers: it’s pretty terrible) as well as some promising developments on the horizon (spoilers: okay, it might not all be bad!).We are so excited to be back with you this season, coming through your headphones with some casual chat about diseases throughout human history!

The podcast explores the history and evolution of birth control methods in the United States, including the development of the birth control pill, male hormonal contraceptives, and legal decisions impacting access. The hosts share personal stories about birth control experiences and celebrate the conclusion of the season, paying tribute to Justice Ruth Bader Ginsburg's advocacy for reproductive rights.

The story of thalidomide is often employed as a cautionary tale - why testing a drug’s safety during pregnancy is crucial or why it’s important to choose the right animal models. Or it’s framed as a success story for drug repurposing or regulation. But those tellings often gloss over the darker lesson of thalidomide: that for some companies, the bottom line is more important than human life. This week, we explore all elements of this infamous drug. We start by examining what we know about how thalidomide causes the severe congenital malformations it’s associated with, and then we dive into the deep, dark history of the drug, complete with a full cast of villains and heroes. Finally, we discuss thalidomide’s controversial comeback as a treatment for myeloma and complications of leprosy. Get out your angry hats for this one, people, because you’ll find yourself asking along with us, “why are humans the way we are?” Learn more about your ad choices. Visit megaphone.fm/adchoices

You’ve heard about smallpox, and you’ve learned about rinderpest. Now it’s time to meet what may be the third disease to ever be eradicated: dracunculiasis, also known as Guinea worm disease. In this episode, we take you through the absolutely remarkable life cycle of this not-so-little worm and the nitty gritty of the havoc it wreaks on a person’s body throughout its journey. Then get out your TPWKY bingo cards, because the history of Guinea worm includes not only mummies and historic papyri but also ancient Rome and fun etymology. To bring us up to speed on the current status of Guinea worm today is Sarah Yerian, Senior Associate Director of the Guinea Worm Eradication Program at the Carter Center. Sara discusses not only how the reduction in prevalence of dracunculiasis has been achieved but also the challenges that remain to finally relegate this worm to the history books.To learn more about the Guinea Worm Eradication Program at the Carter Center, check out the website or follow them on social media: @CarterCenter.

The harm caused by herpes simplex viruses (HSV) 1 & 2 often arises not from the pathology of the viruses themselves but rather from the stigma and shame associated with a positive diagnosis. In this episode, we attempt to lay a clear foundation for understanding not only how these viruses work but also what occurred to change the perception of them from “innocuous infection” to “dreaded disease”. Starting us off with his firsthand account is the incredible Courtney Brame, founder and host of Something Positive for Positive People, a non-profit organization and podcast that aims to provide community support, healing resources, and educational discussions around positive HSV and other STI diagnoses as well as larger issues in sexuality and physical and mental health. We then dive into the meat of the episode, tackling such questions as “how do these viruses hide out in your body?”, “what kind of treatment is available?”, “where did these viruses even come from?” and “why is there such a huge amount of stigma and what can we do about it?”. To help us address this last question is our other fantastic guest, Dr. Ina Park, Associate Professor, University of California San Francisco School of Medicine and Medical Consultant, Division of STD Prevention, Centers for Disease Control and Prevention. We chat with Dr. Park about her new book, Strange Bedfellows, when to have “the talk” with your kids, and how we as individuals can break down some of the shame surrounding a positive STI diagnosis.To learn more about Something Positive for Positive People, head to the website spfpp.org or check out the SPFPP podcast wherever you get your podcasts! You can also follow Courtney on Instagram: @honmychest.And don’t forget to pre-order Dr. Ina Park’s upcoming book Strange Bedfellows: Adventures in the Science, History, and Surprising Secrets of STDs, expected February 2021.

Neglected and ignored by the medical establishment throughout most of its history, sickle cell disease remains one of the most common (and commonly misunderstood) genetic conditions in the world. In this episode, we break down the myriad effects that one nucleotide substitution can have on the human body and discuss the basics of what it means when blood cells sickle. Continuing with the theme of the seen and unseen, we then turn to the history of sickle cell disease, a history of long-standing injustice and the unending fight to raise awareness and provide support for those impacted by the condition. And as always, we wrap up with a discussion on the current global status of sickle cell disease and some exciting new treatment options on the horizon. We are so honored and thrilled to be joined this episode by not one, not two, but three incredible guests! You’ll hear first from Marsha Howe and Sharif Tusuubira, who share with us some of their firsthand experiences living with sickle cell disease. And then in our current status section, Dr. Megan Hochstrasser from the Innovative Genomics Institute walks us through the mind-blowing genome editing approaches being used to treat genetic conditions such as sickle cell disease.You can follow Marsha on her website for her non-profit organization and blog “My Life With Sickle Cell” as well as through her social media channels: Twitter: @MarshaMLWSC, Instagram: @marsha_h181, Facebook: Marsha Howe.
