Vaccines are an essential weapon in fighting disease outbreaks. But how does the time taken to develop vaccines compare to the speed and frequency of outbreaks? And how can we do it better? A feature by Mosaicscience, lets you navigate by disease and see possible scenarios for how many lives can be saved. See it here

VIDEO: Demographic Party Trick 1 – Hans Rosling & Bill Gates: What percent of children get the basic vaccines? (Source: Gapminder 2014) Explaining the global vaccination programs is NOT a party-killer! It’s a Party Trick! In this film Hans asks the question — What percent of children get the basic vaccines? In our Global Ignorance Project we found that the majority of people in Sweden & US don’t know the fact that most children in the world get the basic vaccines. ___________________________________________________________________ VIDEO: The role of vaccines in global health (2010) (Source David Hager on Vimeo) Hans Rosling gives a presentation on the role of vaccines in global health, that was held at the 3rd Northern European Conference on Travel Medicine (NECTM) in Hamburg on May 27th, 2010. Hans Rosling is working for International Health, Karolinska Institute, Medical University Stockholm, Sweden. He lectures about past and contemporary economic, social and environmental changes in the world. ___________________________________________ Is measles vaccination the biggest unrecognized success in global health? (Source Huffington Post 2013) During an interview with CNN this week, Dr. Hans Rosling - iconic co-founder of Gapminder and professor of global health at the Karolinska Institutet - reflected on the state of vaccination in countries around the world. “It’s a beautiful example of global collaboration, life-saving technology, the flagship of aid, and awareness among governments and parents in even the poorest countries - and it’s not known.” Rosling was referring to the fact that a full 84 percent of the world’s one-year-olds are vaccinated against measles - yet American adults are woefully uninformed of this success. ________________________________________________________ VIdeo: River of Myths (Source Gatesnotes via Youtube) "Only by measuring we can cross the river of myths." - Hans Rosling. Hans Rosling shows how measurement reveals incredible progress in saving the lives of children in what were once labeled "developing countries." If the few countries that still have high child mortality rates can follow the path of Ethiopia, preventable child deaths may be history by 2030. We must continue to closely measure this progress. __________________________________________ VIDEO: Love and hate the graph on global vaccination against measles (Source Gapminder via Youtube) Here Rosling explains why he loves and hates this graph. _______________________________________________________ Video: Professor Hans Rosling: Immunisation trends and child survival - 2013 (Source GAVI via Youtube) Professor Hans Rosling delivers a presentation highlighting trends in immunisation, vaccine development and child survival, during GAVI Alliance Mid-Term Review meeting, 30 October 2013. _________________________________________________________________ Hans Rosling at the GAVI Partners' Forum (Source Gavi 2012) Professor Hans Rosling, co-founder of the Gapminder Foundation, doctor and professor of international health at the Karolinska Institute in Sweden, presents "Immunisation and Development" at the Plenary Session Partners’ Forum in Dar-es-Salaam, Tanzania. His presentation showed how GAVI’s mission to increase access to immunisation fits into a new way of looking at global poverty and population trends. Using his trademark computerised graphs and information diagrams, with circles that swarm, swell and shrink like bacteria under a microscope, Dr Rosling this morning demonstrated that the eligibility criteria for GAVI support is unique in recognising a new world order no longer divided along traditional lines between developing and developed countries. “I like GAVI because it is intellectually easier to understand why the line (for eligibility) is here,” said Dr Rosling, pointing to one of his trademark graphs.

Tina posted a topic in Data visualizationWe are experiencing a data revolution. Large amounts of data are increasingly available about our lives as individuals, members of communities, and citizens. Visualizing this information can help translate the most complex of facts and figures into clear stories that inform further study and promote awareness of important topics. Nowadays it is becoming increasingly easy to find and visualize data online. We are interested in data stories and how they relate to our lives. It is not by chance that many innovative data visualization approaches and technologies were developed in data journalism teams at the New York Times, the Wall Street Journal and the Guardian. In public health, specifically, data visualization can help the health policy-makers and the public alike to make sense of the swath of available information: track and explain changes in our health and well-being, track outbreaks of diseases and help us make informed decisions. Better understanding of data and what it means can lead to better choices about our health and well-being, and enable us to make better decisions as family members, neighbours, and citizens. Below are some data visualizations related to vaccine-preventable diseases (VPDs) and vaccines that use data to explain a complex concept. 1. Measles and polio vaccination (share of population that is protected by a vaccine) are used by WHO as essential indicators to measure performance of the country’s health system – see Measuring “State of Health 2020” in Europe. They are proxies that indicate the extent to which governments are investing in the health and well-being of their citizens. My take: Some people think of vaccination as a matter affecting them as individuals, but that’s not how public health experts think. 2. The winner of a Data Journalism Awards 2015 prize, the Wall Street Journal’s “Infectious Diseases and Vaccines” uses data to show how the number of disease cases have plummeted as a result of widespread vaccine usage in the United States. Vaccines have decreased occurrence of several infectious diseases significantly. My take: Measles is one of the most infectious diseases and very difficult to prevent – its chart steals the show. (This visualization created a lot of buzz among information designers on its choice of colour and heatmap design, see here and here .) 3. Here is an explanatory visualization of the data on safety of the HPV vaccine, by the data journalist and information designer David McCandless. My take: Very effective choice to show risk by visually comparing number of people given the vaccine vs those having side effects. 4. The Guardian’s “Watch how the measles outbreak spreads when kids get vaccinated – and when they don’t” helps explain the concept of “herd immunity” – when enough individuals in the population are vaccinated against a disease, they as a community are ensuring that the disease cannot spread easily within the population. My take: It is not enough to achieve on average high vaccination coverage within the country – the risk of an outbreak of disease is higher when unvaccinated people are clustering together within a community. 5. As a data nerd, I wanted to understand how vaccination coverage and our individual choices can affect the course of outbreaks. I found this scientific paper: “The role of vaccination coverage, individual behaviours, and the public health response in the control of measles epidemics: an agent-based simulation for California” (DOI: 10.1186/s12889-015-1766-6) , in which the authors simulated various combinations of vaccination rates, response of the public health authority to outbreak, and the degree to which unvaccinated individuals grouped themselves closely to each other. My take: For a highly infectious disease such as measles, a high vaccination rate, also among smaller groups of unvaccinated people, is essential to control the outbreaks. The figures in the paper are quite good in showing the results of the statistical model. Here’s a challenge – visualize the results in a more simplified way! //@Division of Information, Evidence, Research and Innovation at WHO/Europe //Posts are my own.
