The UK's top doctor, Chris Whitty, says that we should expect another huge pandemic like Covid-19 in the future.
He's worried that the UK doesn't have enough intensive care beds for very sick people, and that this is a political decision that could put us at risk.
Whitty says we need more healthcare workers and better ways to research new illnesses quickly to be ready for the next pandemic.
He also stresses the importance of addressing health inequalities, as they make people more vulnerable to these kinds of crises.
