Gut reaction: the impact of intestinal infections on polio vaccination

Could gut infections be making the standard polio vaccine ineffective in children in low-income countries? Edward Parker, a PhD student at Imperial College London is trying to find out, as he explains in his article commended in the 2014 Max Perutz Science Writing Award.

The Global Polio Eradication Initiative was never meant to last this long.

In 1988, when the campaign was launched, there was considerable optimism that polio would not see the end of the century. Although this deadline has long since passed, the progress made by the eradication initiative should not be underestimated: in what is arguably the greatest onslaught against a disease in history, polio has been reduced from an infection with a global distribution, responsible for 350,000 cases of paralysis each year, to one that is on the brink of extinction. Just 223 cases of the disease were reported in 2012 ― the lowest number on record.

But polio is a wily foe. Despite exhaustive vaccination campaigns, the virus has never been eliminated in Pakistan, Afghanistan, and Nigeria. What’s more, polio has recently been on the move. After cases in Ethiopia, Somalia, Cameroon, Equatorial Guinea, Syria, and Iraq, in May 2014 the World Health Organization declared the spread of polio to be an international public health emergency. [...]

Behind the picture: Rosalind Franklin and the polio model

24 Jul 2013

Retro light fitting or model of a virus? In the latest of our looks at the story behind an image from the MRC archive, Ellen Charman finds out how this collection of giant ping pong balls is linked to Rosalind Franklin’s less well-known research understanding the structure of viruses.

This image, taken at Birkbeck College in 1958, shows the sculptor John Ernest dwarfed by one of his models of the poliovirus, which is seemingly made from giant pingpong balls.

The five-foot model, together with one of the tobacco mosaic virus, was exhibited at the International Science Pavilion of the Brussels’ World Exhibition in 1958, the first major World’s Fair after World War 2. Earlier versions had indeed been made out of ping pong balls and plastic bicycle handlebar grips. [...]
