COVID Variants And Vaccines, U.S. Energy Justice. Feb 5, 2021, Part 1

Will Vaccines Work Against New Variants Of The Coronavirus? The rollout of COVID-19 vaccination programs around the world has been anything but smooth. Complicating the effort is the virus itself. The original coronavirus genome that the current vaccines were based on has mutated. Now, there are three virus variants, and experts are somewhat concerned. How will the vaccines scientists have worked so hard to make fare against these three variants, and future ones? Stephen Goldstein, post-doctoral researcher in evolutionary virology at the University of Utah, joins Ira to talk about what the new numbers on vaccine effectiveness against these variants really mean. This Biden Appointee Is Bringing Justice To Green Energy President Joe Biden has the most ambitious climate change agenda of any U.S. president in history. A large part of the plan is a shift away from fossil fuels to clean energy, like wind and solar power. A new member of Biden’s energy team wants to prioritize something we don’t normally hear from the federal government: energy justice, or making sure communities aren’t left behind, or stepped on, in pursuit of a greener world.  Shalanda Baker, deputy director for energy justice at the U.S. Department of Energy and law professor on leave at Northeastern University in Boston, joins Ira to talk about equitable energy, “The Big Greens,” and her new book, Revolutionary Power: An Activist’s Guide to the Energy Transition. The Thinking Behind New Double-Masking Recommendations If you’re at the grocery store or taking a walk in the brisk winter air, you might see someone sporting the new pandemic trend—double masks. Sometimes it’s a cloth mask over an N95; sometimes it’s two fabric masks layered together. And it’s not because it’s cold out (although the extra warmth is nice). This week the CDC says it’s considering updating its masking guidelines to include wearing two masks, to protect against new, more contagious variants of the coronavirus. Sarah Zhang, staff writer for The Atlantic, joins Ira to discuss whether two masks are really better than one. Plus, how the U.K. is studying whether mixing Astrazeneca’s new vaccine with a dose of Pfizer or Moderna’s formula might actually be more effective at obtaining immunity. Subscribe to this podcast.
