Each year an estimated 1 million children worldwide die as a result of pneumococcal disease. Worst affected are those in poor countries, but pneumococcal bacteria cause disease and suffering in all age groups and in all countries, including Sweden.
There are currently two types of active vaccine: polysaccharide vaccines, which protect against more types of pneumococcal bacteria but cannot be given to children under the age of two, and conjugated vaccines, which can be given to infants but protect against fewer types.
In his thesis, Erik Backhaus, infection specialist at Skövde Hospital and doctoral student at the University of Gothenburg’s Sahlgrenska Academy, looks at all cases of serious pneumococcal disease in children and adults in the Västra Götaland region of Sweden between 1998 and 2001. His studies show that the latest conjugated vaccines theoretically offer protection against around 70% of infections. “But around 95% of infections are caused by serotypes covered by the polysaccharide vaccine,” says Backhaus. “This vaccine cannot be administered to children under two years of age, which means that it cannot be used in those who need it most.”
“This may be due to different routines for admitting patients from nursing homes to hospital and how often blood cultures are performed,” he explains.More cases, fewer deaths
It is hoped that the recently introduced pneumococcal vaccination as part of the standard child immunisation programme will reduce the number of infections among both children and adults.The thesis “Invasive Pneumococcal Infections” was successfully defended at the Sahlgrenska Academy’s Institute of Biomedicine on 13 January.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.
Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
