Government and Public Health

Italy is facing a serious drop in vaccine coverage, which are falling close to – and in some cases even below – the target set by the Minister of Health in the current national plan for vaccine prevention. This is a serious  problem for public health, since, for infections transmitted from man to man (tetanus being an exception), a high coverage is necessary to protect those people that cannot be vaccinated either because of their age or because of clinical reasons, such as for cancer therapies, through the mechanism of herd immunity.

Monitoring health on a large scale through Big Data or using social networks to modify behaviour and risk factors are two relevant examples of how cutting edge technology may provide new and powerful tools against infectious diseases.

Many public and private agencies and bodies gather data from social networks and search engines to try and identify health emergencies and solve the problem: the most common approach is to analyze the search strings used by Google and the texts of blogs, forums and other pages on the Net.

The monographic issue of Vaccine, published in August 2015 under the title “WHO Recommendations Regarding Vaccine Hesitancy”, is a collection of materials produced by a group specifically dedicated to the topic in 2012, under the combined leadership of the WHO and UNICEF.
