Over the past few weeks, India has been experiencing a devastating second wave of COVID-19, recording hundreds of thousands of new cases a day.Evidence is growing that a new variant of the SARS-CoV-2 virus known as B.1.617, first detected in India in October, may be driving this wave.On this week’s Coronapod we talk about the race to learn more about B.1.617, with early results suggesting it may be more transmissible and could cause more severe disease.News: Coronavirus variants are spreading in India — what scientists know so far Hosted on Acast.

In surprise news this week, the US government announced its support for waiving patent protections for COVID-19 vaccines, in an effort to boost supplies around the world.As fewer than 1% of people living in low-income countries have received COVID-19 vaccines, it is hoped that this move is a major step towards addressing this inequity by allowing manufacturers to legally produce generic versions of vaccines. We discuss the next steps that need to be taken to make this a reality, and why there is opposition to the plan.Also on the podcast, we look at another aspect of coronavirus inequity: the sharing of genomic data. Around the world, researchers are racing to upload SARS-CoV-2 genome sequences to repositories, to help in the fight against the pandemic. One popular data repository, GISAID, requires users to sign in and acknowledge those whose data they analyse. Although a growing faction of scientists from wealthy nations are calling for the removal of gatekeeping requirements, scientists in the global south are pushing back, arguing that this will deprive them of credit and chances to participate in big-data analyses.News: In shock move, US backs waiving patents on COVID vaccinesNews: Why some researchers oppose unrestricted sharing of coronavirus genome dataNews: Scientists call for fully open sharing of coronavirus genome dataScience: Coronavirus sequence trove sparks frustrationNew York Times: Pfizer Reaps Hundreds of Millions in Profits From Covid VaccineWashington Post: Poor countries may not be vaccinated until 2024.

Despite warnings, and a number of close calls, drugmakers failed to develop and stockpile drugs to fight a viral pandemic. Now, in the wake of SARS-CoV-2, they are pledging not to make the same mistake again.Around the world, researchers are racing to develop drugs to target COVID-19, but also broad-spectrum antivirals that could be used to treat future viral threats.This is an audio version of our feature: The race for antiviral drugs to beat COVID — and the next pandemic Hosted on Acast.

As COVID-19 vaccine roll-outs continue, attentions are turning to one group: children. While research suggests that children rarely develop severe forms of COVID-19, scientists still believe they could play a key role in transmission and a plan needs to be in place for the longer term. But clinical trials in children are more complicated than those in adults as different ethical and practical concerns need to be taken into account.In this episode of Coronapod, we discuss the ongoing clinical trials to test vaccines in young children, and ask what scientists want to know about safety, and how effective these vaccines might be at preventing disease and transmission.News: COVID vaccines and kids: five questions as trials begin Hosted on Acast.

Reports of rare and unusual blood clots have resulted in several vaccine roll outs being paused while scientists scramble to work out if the vaccines are responsible and if so how.The unusual combination of symptoms, including a low platelet count and clots focussed in the abdomen or brain, seems similar to a rare side effect from treatment with the drug blood thinning drug Heparin - however it is not clear how the vaccines could cause the syndrome.In this episode of Coronapod we discuss the latest theories and ask how scientists are trying to get to the bottom of this important question. Medical regulators maintain that the benefits of these vaccines significantly outweigh the risks. But as uncertainty spreads, we ponder the wider implications of these reports, including the public perception of risk.News: How could a COVID vaccine cause blood clots?
