Future pandemics could be even more lethal than Covid-19 so the lessons learned from the outbreak must not be squandered and the world must ensure it is prepared for the next viral onslaught, one of the creators of the Oxford-AstraZeneca vaccine said. "The truth is, the next one could be worse. It could be more contagious, or more lethal, or both," Prof Dame Sarah Gilbert said in the Richard Dimbleby Lecture, the BBC reported. "This will not be the last time a virus threatens our lives and our livelihoods." Gilbert, a professor of vaccinology at the University of Oxford, said the world should make sure it is better prepared for the next virus. "The advances we have made, and the knowledge we have gained, must not be lost," she said. Efforts to end the Covid-19 pandemic have been uneven and fragmented, marked by limited access to vaccines in low-income countries while the "healthy and wealthy" in rich countries get boosters, health experts say.

Genomic sequencing allowed the world to track new coronavirus variants throughout the pandemic. Now British researchers plan to use it to better understand a host of other respiratory pathogens, from influenza to respiratory syncytial virus (RSV). The work is aimed at shedding more light on known threats and, potentially, emerging ones, the team at the Wellcome Sanger Institute, working with the UK Health Security Agency, said. The world has never had access to the kind of real-time information for these viruses that scientists obtained on SARS-CoV-2 through sequencing millions of genomes, Ewan Harrison, head of the new Respiratory Virus and Microbiome Initiative, told reporters on Monday. That includes granular detail on how they transmit as well as how they evolve in the face of the human immune response. "We hope that by expanding our ability to sequence these viruses routinely, we can build upon the work that's going on COVID, and hopefully supercharge research efforts to understand the transmission of these viruses, but also to help develop new treatments and vaccines," Harrison said.

Lapses in strategies to tackle COVID-19 this year continue to create the perfect conditions for a deadly new variant to emerge, as parts of China witness a rise in infections, the head of the World Health Organization said on Friday (December 2). The comments by WHO Director-General Tedros Adhanom Ghebreyesus mark a change in tone just months after he said that the world has never been in a better position to end the pandemic. "We are much closer to being able to say that the emergency phase of the pandemic is over, but we're not there yet," Tedros said on Friday. The global health agency estimates that about 90% of the world's population now has some level of immunity to SARS-COV-2 either due to prior infection or vaccination. "Gaps in testing … and vaccination are continuing to create the perfect conditions for a new variant of concern to emerge that could cause significant mortality," Tedros said. COVID-19 infections are at record highs in China and have started to rise in parts of Britain after months of decline.
