The slogan Protect the NHS, Save Lives was central to the United Kingdom government's public health campaign during the Covid-19 pandemic in 2020, when people were urged to stay home to reduce pressure on hospitals. The message appeared on television, radio and social media, and the phrase quickly became shorthand for the lockdown rules across Britain. It spread further as news clips and parodies circulated online, and it is still used today in retrospectives, documentaries and classroom material about the pandemic because it instantly signals that period.
