Pennsylvania State University Classroom rosters combined with human-networking theory may give a clearer picture of just how infectious diseases such as influenza can spread through a closed group of people, and even through populations at large. Using high-school schedule data for a community of students, teachers, and staff, Penn State University's Marcel Salathé, an assistant professor of biology, and Timo Smieszek, a post-doctoral researcher, have developed a low-cost but...

How to predict ways in which population vaccinating behavior might unfold during a vaccine scare Worries over vaccine risks can allow preventable contagious diseases, such as measles and whooping cough, to make a comeback. A new study, published in PLoS Computational Biology, shows how to predict ways in which population vaccinating behavior might unfold during a vaccine scare. "These findings might help in evaluating and developing global immunization programs and public health...

A unique and innovative analysis of how social media can affect the spread of a disease has been designed and implemented by a scientist at Penn State University studying attitudes toward the H1N1 vaccine. Marcel Salathé, an assistant professor of biology, studied how users of Twitter -- a popular microblogging and social-networking service -- expressed their sentiments about a new vaccine. He then tracked how the users' attitudes correlated with vaccination rates and how...

Vaccine scares may do more harm than previously believed to a population's 'herd immunity' Public immunization efforts may be much more sensitive than previously realized to small changes in the perceived costs or risks of vaccination, scientists at Harvard University report this week. In some cases, the spread of vaccine avoidance via social networks can make the difference between a minor, localized outbreak and an epidemic four times as large. The finding, published in Proceedings of the...

Trial results in rural Canadians show effect of herd immunity Results of a clinical trial conducted in a largely self-contained religious community during the 2008-09 influenza season show that immunizing children against seasonal influenza can significantly protect unvaccinated community members against influenza as well. The study was conducted to determine if immunized children could act as a barrier to limit the spread of influenza to the wider, unvaccinated community, a concept known as...

NEW YORK (Reuters Health) - Evidence from a recent large measles outbreak in the Republic of the Marshall Islands (RMI) indicates that, in very crowded living conditions, routine two-dose measles vaccination schedule reaching most of the inhabitants is required to provide measles "herd immunity." Herd immunity occurs when a large segment of the population is vaccinated against a particular microbe, which, in turn, makes the odds of infection among unvaccinated individuals low. The...

NEW YORK (Reuters Health) - In 2003, routine immunization of US children with a vaccine that protects against bacterial infection prevented nearly 30,000 cases of severe disease, researchers from the Centers for Disease Control and Prevention report. The 7-valent pneumococcal conjugate vaccine (PCV7) vaccine protects against a variety of infections caused by Streptococcus pneumoniae, many of which, such as meningitis or pneumonia, can be fatal. "Routine use of PCV7 in young children...
