The severity of the pandemic in the UK is now surpassing where it was last spring. Hospital admissions are higher, and daily COVID-19 deaths will soon eclipse the peak of April 2020. As a result, the UK government is delaying giving the second, top-up dose of the COVID-19 vaccines. This is sound logic, explains professor of medicine Paul Hunter: it means many more people can be given a protective first dose now.

Because these are new vaccines, there isn’t concrete evidence on how delaying the second dose will affect performance. However, data from testing, together with knowledge about other vaccines, suggests the delay shouldn’t make the vaccine less effective or leave people vulnerable after taking their first dose.

Tuesday’s storming of the US Capitol was fueled in part by the QAnon movement and online conspiracies, writes Marc-André Argentino, and this gave the world a stark warning of how digital propaganda and misinformation can have dangerous impacts offline. Experts from across The Conversation have also examined the protesters’ motives, whether the event qualifies as a coup, and the significance of social media platforms locking President Trump’s accounts.

And in this brilliantly written piece, Rafael Euba answers one of life’s big questions: how do you move on from a lost love?

QAnon and the storm of the U.S. Capitol: The offline effect of online conspiracy theories

Marc-André Argentino, Concordia University

Conspiracy theories spread online are the backbone of Donald Trump's falsehoods about his loss in the U.S. election. The real world consequences of those conspiracies have now exploded.
