| The head of Britain’s Covid-19 genomics programme has warned that there will be a need for regular booster jabs to protect people against the virus as new potentially vaccine-busting variants emerge. | The head of Britain’s Covid-19 genomics programme has warned that there will be a need for regular booster jabs to protect people against the virus as new potentially vaccine-busting variants emerge. |
| “We have to appreciate that we were always going to have to have booster doses; immunity to coronavirus doesn’t last forever,” Sharon Peacock, UK Covid-19 Genomics (COG-UK) chief, told Reuters at the Wellcome Sanger Institute’s Cambridge campus on Monday. | “We have to appreciate that we were always going to have to have booster doses; immunity to coronavirus doesn’t last forever,” Sharon Peacock, UK Covid-19 Genomics (COG-UK) chief, told Reuters at the Wellcome Sanger Institute’s Cambridge campus on Monday. |
| Peacock, whose COG-UK programme has sequenced half of the world’s mapped Covid-19 genomes, said she was confident new variants would emerge that would render the current vaccines ineffective. | Peacock, whose COG-UK programme has sequenced half of the world’s mapped Covid-19 genomes, said she was confident new variants would emerge that would render the current vaccines ineffective. |
| “We already are tweaking the vaccines to deal with what the virus is doing in terms of evolution – so there are variants arising that have a combination of increased transmissibility and an ability to partially evade our immune response,” she said. | “We already are tweaking the vaccines to deal with what the virus is doing in terms of evolution – so there are variants arising that have a combination of increased transmissibility and an ability to partially evade our immune response,” she said. |
| The genomics chief said the “cat and mouse” battle with the virus will require international cooperation. COG-UK was set up a year ago by Peacock and the British government’s chief scientific adviser, Patrick Vallance, and has sequenced 346,713 genomes out of a total of 709,000 genomes mapped worldwide. | The genomics chief said the “cat and mouse” battle with the virus will require international cooperation.

| To date, more than 24 million people in the UK have received at least their first vaccine dose; all vaccines being used have demonstrated considerable efficacy against the virus variants prevalent in Britain. | To date, more than 24 million people in the UK have received at least their first vaccine dose; all vaccines being used have demonstrated considerable efficacy against the virus variants prevalent in Britain. |
