Swine Flu vaccination: voluntary system works

11.02.2010
Social interaction between neighbours, work colleagues and other communities and social groups makes voluntary vaccination programs for epidemics such as Swine Flu, SARS or Bird Flu a surprisingly effective method of disease control.

New research published today, Thursday 11 February, in New Journal of Physics (co-owned by the Institute of Physics and German Physical Society), shows that contact with others can positively influence individuals to choose voluntary vaccination when considering the pros and cons.

The group of Chinese researchers found that in scale-free networks — social networks with an uneven distribution of connectedness such as neighbourhoods, work places or gyms — the so-called hub nodes, people with multiple social connections, tend to choose to vaccinate themselves as they are at higher risk of infection from others, thus containing the spread of epidemics.

Based on their studies, the researchers have observed that at the beginning of an epidemic, when levels of infection are high, a large number of people will gradually take vaccination. As the effects of the temporary vaccination wear off, a second wave of outbreak will occur, however on a less severe level due to the number of individuals with still effective immunisation.

This is why outbreaks of disease and voluntary vaccination occur periodically, eventually settling down to a stable state. Individuals with a large social network play a crucial role in this cycle as, given information on the spread of the disease is freely available, the majority of them will choose voluntary vaccination.

In order to set up an effective vaccination strategy it is therefore crucial to affect the hub nodes' willingness to vaccinate, which can potentially be negatively influenced by factors such as the risk of infection, the coverage of disease and the cost of vaccination.

As the researchers write, "Sometimes the high costs of vaccination or misunderstanding the side effect of vaccinations can reduce the enthusiasm for taking vaccination. In this case the external incentives such as subsidy of vaccination cost would be helpful in enhancing the vaccination inclination of the hub nodes."

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
