On 22 May 2024 Professor Trisha Greenhalgh and colleagues published their awaited narrative review and meta-analysis summarizing a broad evidence base on the benefits—and also the practicalities, disbenefits, harms and personal, sociocultural and environmental impacts—of masks and masking. This surely lays the debate to rest and is a basis for clear policy measures and further research agendas.

Concluding comments
We shall see how this research is received over the coming days and weeks, but it is a real glimmer of hope for clinically vulnerable families and has the potential to lead to meaningful policy and communication changes that would reduce the incidence of Covid, and an end to the kind of abuse we face as discussed in my recent blog. The findings are discussed further in a piece in the Conversation.
Unfortunately, this publication has landed on a big news day in the UK as speculation mounts that the PM is about to call a general election. However, on the positive side, my assessment is we will only make progress in finally tackling Covid-19 and improving the lives of the clinically vulnerable if there is a change of government.
