Britain's pandemic modellers say future large waves of COVID possible

There is a realistic possibility of large waves of COVID-19 infection in the future in Britain and such waves might even be considered likely, epidemiologists who model the COVID-19 pandemic to inform government advice have said. British Prime Minister Boris Johnson has ditched legal restrictions in England, saying that, while the pandemic was not over, Britain needs to learn to live with COVID. The Scientific Pandemic Influenza Group on Modelling, Operational sub-group (SPI-M-O) said the emergence of new viral variants was the biggest unknown factor in the medium-to-long term, along with waning population immunity and changes in mixing patterns.
