Covid-19: ‘The Rise Of The RNA Vaccines’ (Podcast)

Benjamin Thompson, Noah Baker and Elie Dolgin discuss RNA vaccines.

In this episode:

01:16 How RNA vaccines came to prominence

In less than a year, two RNA vaccines against COVID-19 were designed, tested and rolled out across the world. We discuss these vaccines’ pros and cons, how RNA technology lends itself to rapid vaccine development, and what this means for the fight against other diseases.

09:20 The hurdles for trialling new COVID-19 vaccines

Multiple candidates for new COVID-19 vaccines are still being developed, which may offer advantages over the vaccines currently available. However, running placebo-controlled trials of these candidates is becoming increasingly difficult, so researchers are looking for different ways to evaluate them.

14:45 How long will COVID vaccines be effective?

There is much concern around the world about two faster-spreading variants of SARS-CoV-2. We get an update on whether these variants could render vaccines ineffective.

Covid-19: ‘How mRNA Vaccines Work’ (Video)

Messenger RNA—or mRNA—vaccines have been in development for decades, and are now approved for use against COVID-19. Here’s how they work and what you should know about them. Visit https://www.jhsph.edu/covid-19​ for even more resources.

Covid-19: ‘When Will The U.S. Get The Vaccine?’

The initial doses of Pfizer and BioNTech’s Covid-19 vaccines could go out next month, if the FDA grants emergency authorization. There are also three other promising vaccine candidates in the pipeline from AstraZeneca, Moderna, and Johnson & Johnson. The process of distributing the vaccine to the 330 million people living in the U.S., however, could prove a logistical challenge. Here’s a look at how the federal government plans to do it.

Science Podcast: Pfizer Covid-19 Vaccine Review, Bacteria On Asteroids

Scientists this week announced hopeful results in two of the big COVID-19 vaccination trials. Trudie Lang, Professor of Global Health at the Nuffield Department of Medicine, Oxford, describes some of the methodology used, what the efficacy statistic means, and how the novel approach of inserting mRNA rather than deactivated virus parts, is so exciting. 

Prof Charles Cockell has been investigating how bacteria might be grown in space on lumps of asteroid to extract precious minerals, and as Kim McAllister reports, his lab is itself in orbit. And it is just a few weeks since the UK, and several other countries, signed up to a set of bilateral agreements with the US called the Artemis Accords. These are an attempt to update previous outer space treaties on how countries – and indeed companies – might mine and use resources in space, given that no-one can currently legally claim sovereignty. As Dr Thomas Cheney of the Open University and Prof Jill Stuart of the LSE describe, the Accords have been greeted in certain quarters with some discord.
