Optimal flu vaccine priorities developed at Clemson University

24.08.2009
Optimal control of the spread of the seasonal flu and H1N1 is achieved by prioritizing vaccinations for schoolchildren and for adults aged 30 to 39 in the United States. Those are the findings of a new study by Clemson University mathematician Jan Medlock and colleague Alison Galvani of the Yale University School of Medicine.

The researchers have developed models that challenge the recommendations of the Centers of Disease Control and its Advisory Committee on Immunization Practices for which segment of the population should be vaccinated against the flu. In their findings, published Aug. 20 in Science Express http://www.sciencexpress.org, the researchers say the U.S. population can be best protected by stopping the high levels of transmission among schoolchildren and to their parents, despite the fact that other age groups may suffer more severe symptoms if they catch the flu.

"Current flu vaccination recommendations include children under age 5 and for seasonal flu, people over age 50," said Medlock. "The vaccines would be better used to prevent transmission within schools and out to parents, who then spread the flu to the rest of the population. The CDC recommendations have been changing the last few years, particularly due to the new H1N1 strain, and have been moving in the right direction."

The researchers studied mortality data from the United States and survey-based data on infectious contacts from the influenza pandemics of 1918 and 1957, taking into consideration multiple ways to quantify the impact of an influenza outbreak: deaths, infections and other measures that vary with the age of those infected. Strikingly, they found that all the measures led to the conclusion that schoolchildren and their parents are the best groups to vaccinate when even a modest amount of an effective vaccine is available.

The World Health Organization has announced the possibility of shortfalls in the production of H1N1 vaccines this year due to the slow growth of the swine-origin H1N1 in chicken eggs. The researchers concluded that when vaccine availability is limited or when vaccine efficacy is low, optimal allocation of vaccines is imperative to minimize the spread of the illness.

The research was funded with a $650,000 grant from the National Science Foundation.

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

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...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
