Ivermectin is a cheap, widely available, anti-parasitic drug that has been proposed by many as a possible treatment for COVID-19. Dozens of trials have been started, but results have been far from clear, with inconsistent results further confused by high profile paper retractions. Nonetheless many countries have recommended the use of Ivermectin, despite WHO advice to the contrary.Now a group of researchers have found suspect data in another influential paper which claimed a Ivermectin caused a 90% reduction in fatality. The paper, published at the end of 2020, has since been withdrawn pending investigation. In this episode of Coronapod we ask what this might mean for Ivermectin, and what's next for the controversial drug.Correction: at 2:53 when discussing two discredited studies, we mistakenly say that the papers say "both drugs worked really well". In fact, this retracted study from the Lancet claimed that the drug hydroxychloroquine caused harm.

The UK government has announced that virtually all COVID restrictions will be removed in England on Monday 18th July. This will do away with social distancing requirements, allow businesses to re-open to full capacity and remove legal mask mandates. This decision comes, however, amidst soaring infections rates in the country, driven by the delta variant.Now scientists are questioning the wisdom of this policy and asking whether the combination of high transmission and a partially vaccinated population could provide the perfect breeding ground for vaccine-resistant variants - a possibility which could have devastating global consequences.News: Why England’s COVID ‘freedom day’ alarms researchers Hosted on Acast.

Since the beginning oft he pandemic, researchers have searched for a biomarker which indicates immune protection from COVID-19 known as a correlate of protection. Now, the team developing the Oxford–AstraZeneca COVID-19 vaccine have published the first results of their so-called 'breakthrough study' which indicated puts forwards thresholds of neutralising antibodies that they suggest correlate with protection.

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.

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.

In 2020, the artificial intelligence (AI) GPT-3 wowed the world with its ability to write fluent streams of text. Trained on billions of words from books, articles and websites, GPT-3 was the latest in a series of ‘large language model’ AIs that are used by companies around the world to improve search results, answer questions, or propose computer code.However, these large language model are not without their issues. Their training is based on the statistical relationships between the words and phrases, which can lead to them generating toxic or dangerous outputs.Preventing responses like these is a huge challenge for researchers, who are attempting to do so by addressing biases in training data, or by instilling these AIs with common-sense and moral judgement.This is an audio version of our feature: Robo-writers: the rise and risks of language-generating AI Hosted on Acast.

From a sore arm to anaphylaxis, a wide range of adverse events have been reported after people have received a COVID-19 vaccine. And yet it is unclear how many of these events are actually caused by the vaccine. In the vast majority of cases, reactions are mild and can be explained by the body's own immune response. But monitoring systems designed to track adverse events are catching much rarer but more serious events. Now scientists need to work out if they are causally liked to the vaccine, or are just statistical anomalies - and that is not an easy task.News: Why is it so hard to investigate the rare side effects of COVID vaccines?Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.Never miss an episode: Subscribe to the Nature Podcast on Apple Podcasts, Google Podcasts, Spotify or your favourite podcast app. Head here for the Nature Podcast RSS feed .
