In the first Talk Evidence of 2022, we'll be asking about the evidence for isolation - now that isolation periods are being reduced, or even stopped in the event of a negative lateral flow test, we'll find out what data that's based on, and if it's appropriate. Vaccinations and treatments for covid-19 have been the one major success story of the pandemic, but that doesn't mean we should abandon the principles of openness and transparency when it comes to scrutinising the data - we'll hear what access to the data which underlies regulatory approval could do now. Finally, the impacts of climate change were set out in a WHO report in November last year - and recent weather seems to underline their conclusions. We'll discuss new evidence linking the environment and health, and ask what clinicians can do with that.
