The UK government has admitted it used phone data to analyse people's movement patterns without their knowledge as part of a vaccination study, a new report claims. Officials are said to have preserved the subjects' anonymity.

The Telegraph cited a report by the Independent Scientific Pandemic Insights Group on Behaviours (SPI-B) which said researchers from the University of Oxford discretely used data from mobile phones as part of their study into how vaccination affects people's lifestyles.

SPI-B advises the Scientific Advisory Group for Emergencies (SAGE), which in turn advises the government. The University of Oxford, which developed the Covid-19 vaccine along with the British-Swedish pharmaceutical firm AstraZeneca, conducted the study on SPI-B's behalf.
