The Jump is a BBC Radio 4 series exploring how viruses can cross from animals into humans to cause pandemics.
Our podcast sees expert journalists from the magazine discuss the biggest science stories to hit the headlines each week – from technology and space, to health and the environment. New Scientist Weekly features updates and analysis on the latest developments in the covid-19 pandemic.

The authorisation of the Pfizer drug is a big step, said Patrizia Cavazzoni at the FDA’s Center for Drug Evaluation and Research. Paxlovid will be prescribed to over-12s with mild or moderate covid who are at risk of severe disease or hospitalisation.
The first covid-19 antiviral pill has been approved in the US by the Food and Drug Administration (FDA). “An individual infection could be relatively mild for the vast majority of people, but the potential for all these infections to come at once and put serious strain on the NHS remains,” said Mark Woolhouse at the University of Edinburgh. They found that omicron cases were around two thirds as likely to be hospitalised as delta cases, however the small size of the study and the fact that many of the omicron cases were in younger, less vulnerable groups, means this cannot be taken as an indication of the variant’s severity. Only about 672 of the cases sequenced were due to the omicron variant. A University of Edinburgh team looked at over 150,000 covid-19 cases from 1 November to 19 December. “Multi-layered mitigations and limiting socialisation over Christmas is still vitally important.”Ī separate study in Scotland has also found that omicron is associated with proportionally fewer hospitalisations. “Small reductions in protection against severe disease can translate to large differences at population level,” she says. The study suggests that two doses of coronavirus vaccine is not enough to combat omicron alone, tweeted Deepti Gurdasani at Queen Mary University of London. “The study suggests there is no reduction in the severity of omicron compared to delta for the doubly vaccinated, indicating that it is not milder,” James Naismith at the University of Oxford told the Science Media Centre. “Given the high transmissibility of the omicron virus, there remains the potential for health services to face increasing demand if omicron cases continue to grow at the rate that has been seen in recent weeks,” he said in a statement. However this reduced risk is offset by the diminished efficacy of coronavirus vaccines against omicron, and the variant’s high transmissibility, said Neil Ferguson at Imperial College London, who worked on the study.
