Coronavirus antibody tests explained: what are they and do they work?

-

The tests seek to determine whether a person has been exposed to the virus, but many early versions are deeply flawed

Health officials in Germany, the UK and the US are looking at antibody testing to figure out when and how their countries could open back up. Some authorities are even considering issuing “immunity passports” that would help key workers safely and quickly return to their jobs.

But some early Covid-19 antibody tests, and the research that hinges on them, have been deeply flawed. Infectious disease experts warn that while reliable antibody tests could eventually reveal much about how the disease spreads and how deadly it is, it is too early to draw any definitive conclusions from screening studies.

The Glasgow Effect: examining the city's life expectancy gap – a photo essay

Documentary photographer Kirsty Mackay examines the causes of the ‘Glasgow Effect’ in a highly personal project. She looks at Glasgow’s excess mortality in comparison to the UK average and shifts the focus from the individual to government policy. The Fish That Never Swam will be published as a book later this year. In Glasgow people’s lives are cut short: male life expectancy in Possil is 66, in Penilee three young people took their own lives within the space of one week this June, suicide in Glasgow is 30% higher than in English cities, male life expectancy is seven years short of the UK average and women’s is four years less. This is not isolated to areas of deprivation – Glaswegians across all social classes experience a 15% reduction in life expectancy. We have known about the “Glasgow Effect” for more than a decade.

From the raw For Sama to the rip-roaring Rocketman, top-notch films from around the world graced the big screen. The Observer’s film critic introduces his 10 best movies of 2019 2019 was the year that Netflix movies came of age, and ageing actors were made young again. At the 91st Oscars in February, the bland Green Book beat the superior BlackKklansman to the best picture award, although Spike Lee won his first competitive Oscar in the adapted screenplay category. Rami Malik scooped best actor for his portrayal of Freddie Mercury in Bohemian Rhapsody , but best actress Olivia Colman ( The Favourite ) stole the evening with one of the funniest and most self-deprecating acceptance speeches ever (complete with raspberry-blowing). More significantly, Alfonso Cuarón’s Roma won for cinematography, direction and best foreign language film, despite naysayers’ complaints that Netflix-backed movies were essentially made-for-TV films. That attitude is now history: in the forthcoming awa...
