Would herd immunity stop the spread of coronavirus?

Even if achievable, the strategy would kill too many people, say scientists

Like the Covid-19 virus itself, the idea of herd immunity has surged back into public life having been suppressed for months. It was initially touted as a way to hold back the pandemic – by allowing sufficient numbers of infections to occur and so reduce numbers of non-immune potential hosts for the virus. The disease would then stop spreading, it was argued.

The notion quickly fell out of favour when researchers highlighted the high death toll that would have to occur in the UK before herd immunity was achieved. Nevertheless, the idea has now bubbled back and is again making headlines.

‘Poisoning the Pacific’: New book details US military contamination of islands and ocean

More than 12,000 pages of US government documents show military operations contaminating the Pacific with radioactive waste, nerve agents, and chemical weapons like Agent Orange

In 1968, Leroy Foster was a master sergeant in the US Air Force, assigned to the Anderson Air Force Base in Guam, a United States island territory in the Pacific. The day after he arrived on the island, he recalled being ordered to mix “diesel fuel with Agent Orange”, then spraying “it by truck all over the base to kill the jungle overgrowth”.

Soon after, Foster suffered serious skin complaints and eventually fell sick with Parkinson’s and ischemic heart disease. Later, his daughter had cancer as a teenager, and his grandchild was born with 12 fingers, 12 toes, and a heart murmur. Foster died in 2018.

Fresh Azerbaijani shelling shatters peace after fragile ceasefire agreed

Any hope for a truce in the long-running conflict in the Armenian enclave of Nagorno-Karabakh was short-lived

The streets of Stepanakert were quiet as a ceasefire went into effect on Saturday afternoon, but the local population’s ears were still ringing from shelling and drone strikes that have decimated this highland town over the past 13 days.

The peace – and any hope of a lasting truce – was short-lived. Air-raid sirens in Artsakh, a de facto Armenian republic inside Azerbaijan’s borders, were screaming again before nightfall. Residents who have refused to flee the assault retreated back into bomb shelters and basements, bracing for another sleepless night.

Reports of rare bat species in ancient woodland being cleared for high-speed rail line

A critic’s view: the delusion of Trump’s Covid-19 victory photo

President’s pose on the White House balcony was a manic act of narcissistic theatre

The trouble with Trump is that, as he told Bob Woodward, “I bring rage out.” It’s hard to see this picture of him posing maskless on the White House balcony after “winning” against Covid without the red mist coming down.

To anyone with a sense of history, the echo of Mussolini on the balcony of Rome’s Palazzo Venezia is unmistakable. But many of his core voters may know as little history as he does and, besides, this is the White House, with American flags flanking him – still for many a stage of democracy, not dictatorship. Perhaps the real shock of the pose is its delusion. There is no crowd – he’s performing for himself and the camera.

Pelosi says Trump’s Covid medication has him ‘in an altered state’ – video

Nancy Pelosi has announced that the House will invoke the 25th amendment, which gives Congress power to evaluate the health and stability of US presidents in conducting the duties of their office. 

Although the amendment enables the House Speaker to create a commission to review the president’s fitness for office, the House of Representatives would not be able to remove Donald Trump from office without the agreement of the vice-president, Mike Pence, and members of the cabinet. 

Pelosi insisted the proposed commission was not about Trump, but said of the president: 'He is under medication. Any of us who is under medication of that seriousness is in an altered state.'
