Although it can be life-threatening, most people recover with few remaining problems. The disorder often occurs after an infection; the body's immune system attacks the peripheral nervous system.
The vaccine was approved in June 2006 for use in girls and women age 9 to 26 to prevent infection with human papilloma virus (HPV) types that are the most common cause of cervical cancer. More than 16 million doses of the vaccine have been distributed.
For the study, researchers examined data from the Vaccine Adverse Event Reporting System, which is managed by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA).
There were 36 cases of Guillain-Barré reported after HPV vaccination in the United States from 2006 to 2008. The disorder occurred within six weeks after vaccination in 75 percent of the people. In 20 of the people, or 60 percent, HPV was the only vaccine they received at the time, while 16 people, or 40 percent, received the HPV vaccine along with other vaccines.
"Our results show that Guillain-Barré is not occurring more often after HPV vaccination than it does in the general population," said study author Nizar Souayah, MD, of the University of Medicine and Dentistry of New Jersey in Newark and a member of the American Academy of Neurology. "However, the fact that most of these cases occurred within six weeks of vaccination does warrant careful monitoring for any additional cases and continued analysis."

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
