Study recommends strategies for distributing flu vaccine during shortage

05.10.2006
When faced with potential vaccine shortages during a flu outbreak, public health officials can turn to a new study by mathematical biologists at The University of Texas at Austin to learn how to best distribute the vaccine.

The scientists used contact network epidemiology to model various vaccine distribution strategies, including the United States Centers for Disease Control strategy of targeting high-risk groups, like infants, the elderly and people with health complications. They also tested the idea of targeting school children, who are critical vectors in moving diseases through communities.

They found that the best vaccine distribution strategy depends on the contagiousness of the flu strain.

"If we only have a limited flu vaccine supply, the best distribution strategy depends on the contagiousness of the strain," says Dr. Lauren Ancel Meyers, assistant professor of integrative biology. "We can more effectively control mildly contagious strains by vaccinating school children, while we can more effectively control moderately and highly contagious strains by vaccinating high-risk groups."

If there is no information available about the contagiousness of a flu strain or if the vaccines are only available after the outbreak is underway, the study recommends prioritizing vaccines for those people in high-risk groups who can experience the greatest complications due to the disease.

Meyers and her colleagues based their contact network models on information from Vancouver, British Columbia. While other mathematical models of disease transmission assume all members of a community are equally likely to infect each other, contact network models take the relationships among people into account.

Meyers says this allowed them to make more detailed and reliable predictions about infectious disease transmission.

"Given that vaccine shortages are likely (as occurred at the start of the 2004 flu season) and that we are unlikely to have a large vaccine supply if a new strain of pandemic flu emerges in human populations, this study offers quantitatively grounded recommendations for public health officials who may be forced to make rapid life-and-death decisions," says Meyers.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
