The project was subsequently extended to ten Italian Regions. This led to the creation of the VaccinarSì Network, whose websites are publicly owned. The aim of this work was to present the framework of the websites of the VaccinarSì Network and to analyse user behaviour in the pre-COVID-19-era (dating from each website’s publication until 31 January 2020) and in the COVID-19-era (from 1 February 2020 to 31 January 2021). Some metrics such as the number of visits to the site (sessions, number of users and average session duration), user behaviour (pages viewed, bounce rate and organic search) and the session acquisition path (direct traffic, referrals and social traffic) were searched, extrapolated and processed with Google Analytics. Qualitative and normally distributed quantitative variables were summarised with their absolute (relative) frequencies and means. Statistical differences between the means of the two periods were evaluated through paired t-test. A two-tailed p-value less than 0.05 was considered to be statistically significant. When the total values recorded over the period were compared, an overall increase in metrics was observed—the number of individual users, visits and individual pageviews rose in a statistically significant way. Our study aimed to highlight how combining disciplines such as health education and digital communication via Information and Communication Technologies (ICT) represents the best strategy to support citizens. This approach gives them the tools to become independent and responsible players that are capable of voluntarily and consciously choosing to adhere to vaccination programs. The VaccinarSì Network’s goal for the future is to reach an even wider audience. By building each user’s critical knowledge, this network enables users to be active components of a wider, more empowered community. Quick and cheap access to the internet as well as the vast number of registered users of mobile applications (apps) have enabled the Web to become an effective tool for spreading information [1] [2] [3] [4] . Approximately half of the world's population regularly use social media-5.19 billion people own a mobile phone and 4.54 billion people are regularly connected to the Internet [5] . Moreover, the current pandemic, and the resulting social isolation imposed on the population, has further contributed to the increase in use of digital platforms [6] [7] [8] [9] . For some time now, Public Health has also been making use of modern Information and Communication Technologies (ICT) to reach various population groups and to obtain better health conditions for all [10] [11] [12] . This practice, known as digital health or e-health, provides healthcare through the use of digital tools (e.g., web sites and social media networks) to be delivered in easy-to-understand language [13] [14] [15] . On the other hand, digital communication tools in public health, if misused, can act as a conduit for conflicting and misleading information, negatively impacting the health choices of each individual [16] [17] [18] . In particular, during the COVID-19 pandemic, repeated media exposure to the news, discrepancies in the number of infections and mortality figures reported in different countries, as well as conflicting opinions in the media about the urgent need for a vaccine made it difficult for people to find reliable sources of information [19, 20] . Moreover, a low accessibility to technology due to various societal and social factors (i.e., digital divide) make finding correct information even more difficult for those who need it most [21] . Such factors further highlighted the importance of e-health in providing information support for users [22] [23] [24] . A person's decision-making process regarding health choices is, indeed, strongly influenced by what they read online, especially in relation to health issues such as vaccination [25] [26] [27] . According to the World Health Organization (WHO), pandemic-related interruptions in vaccination services and conflicting information on the Internet about SARS-CoV-2 vaccines have further affected vaccination compliance [28] [29] [30] . In particular, a worrying decline in vaccination coverage for DTaP, measles and polio has been observed in at least 68 countries worldwide, since early 2020 [28, 29] . In Italy, during the same period, several regions reported a decrease in childhood and adolescent vaccination coverage for reasons such as-(i) the lack of personnel normally employed in vaccination services, (ii) citizens' concerns about accessing health services and (iii) unjustified interruptions to active calls for vaccination sessions [24, 29] . In this context, the use of e-health by health institutions to counter the phenomenon of Vaccine Hesitancy and to facilitate access to services has acted as an opportunity to educate citizens towards informed and conscious health decisions [31] [32] [33] [34] . Based on the above premises, taking the metrics of the Italian VaccinarSì network (medical and scientific communication websites on vaccinations in Italy) as a starting point, this study aimed to describe and analyse user behaviour recorded before and during the COVID-19 period. It also evaluated the strategies necessary to counteract cyber disinformation through the potential offered by ICTs. The VaccinarSì website (www.vaccinarsi.org) came into being on 8 May 2013, as part of a health communication project led by the Italian Society of Hygiene (S.It.I.). Its organisational structure consists of three coordinating units-(i) a directive unit (restricted board) composed of 5 experts in Hygiene and Preventive Medicine; (ii) a scientific committee composed of 20 public health professionals whose expertise guarantees the quality of the information published; and (iii) an operational board composed of 36 experts (hygienists, infectivologists, paediatricians and health communication professionals), whose task it is to update information and provide advice/correspondence to users. In Italy, the reform of Title V of the Constitution (Constitutional Law no. 3 of 18 October 2001) [35] , determined the almost exclusive responsibility of the Regions, for the organisation and management of the health service. Meanwhile, the State is responsible for establishing the "essential" health services (Livelli essenziali di assistenza -LEA)including vaccines-that all Regions must guarantee to citizens, wherever they reside. As such, the Regions, while guaranteeing the vaccines included in the LEAs, are also free to offer further vaccinations to their citizens. From an organisational point of view, they can also use different supply terms and conditions. In the Italian healthcare panorama, therefore, vaccination policies have been characterised by strong territorial heterogeneity. Thus, vaccination information/communication strategies have also needed to be developed at a regional level. For this reason, in 2014, the Centre for Disease Prevention and Control (CCM) of the Ministry of Health funded a multicentre project that provided for the creation of a VaccinarSì website (VaccinarSì Network) [36] for each of the participating Italian regions (Tuscany: www. vaccinarsintoscana.org; Apulia: www.vaccinarsinpuglia.org; Liguria: www.vaccinarsinliguria. org; Sicily: www.vaccinarsinsicilia.org; Veneto: www.vaccinarsinveneto.org, Latium (www. vaccinarsinlazio.org) and Sardinia: www.vaccinarsinsardegna.org). In the following years, other regions also joined the project: Campania (www.vaccinarsincampania.org), Marche (www.vaccinarsinellemarche.org) and Trentino Alto Adige (www.vaccinarsintrentino.org). In January 2020, the region of Sardinia also published an English-language version of the portal (www.vaccinarsinsardegna.org/en). The network's web portals are structurally identical to the national site in terms of organisation and content, apart from one section that is adapted to the territorial context and is specific to each region. The network is hosted on a dedicated server. To create the website, a preliminary analysis of the epidemiological framework on the national and international scene was carried out to discern the potential determinants of vaccination hesitation and to develop in-depth information. The contents of the website are organised into 7 sections: Vaccine-preventable diseases (VPDs): This section contains a brief description of the infectious diseases for which vaccination is available. Available vaccines: The methods, rules and indications relating to the administration of a vaccine are dealt with in this section. It also contains a direct reference to the corresponding disease. Vaccine benefits and risks: In this section, the benefits of vaccination and its future prospects are presented and discussed, alongside insights into the real risks related to vaccination practices. Countering misinformation: The articles in this section analyse and respond to the main theories of the anti-vaccination movements. These movements operate mainly on the Internet, spreading experimental evidence and news that is not supported by data. This results in misleading consequences, inaccurate results, illusory myths and urban legends-or in a word, disinformation. Travel and vaccinations: In this section of the site, the main issues linking international travel and planned vaccinations are discussed. News Section: A communication task force is responsible for periodically publishing short news reports on the following topics-epidemiological data on vaccinepreventable infectious diseases (outbreaks and epidemics); immunisation guidelines and programmes; and health education and health communication. Once published on the portal, each news item is automatically forwarded by email to all VaccinarSì subscribers, via a newsletter. Regional Section: This section provides up-to-date information on vaccination clinics (locations, addresses, opening hours and contacts) in the region, the vaccines offered and terms and conditions, as well as the health promotion initiatives implemented locally. In order to respond to the various information needs of users, the collection and drafting of the contents present on the VaccinarSì Network is organised into three information levels for each topic covered-(i) title and abstract; (ii) short essay; and (iii) long article. The network's activities are described from each portal's publication date up until 31 January 2021. The network was analysed by distinguishing between a pre-COVID-19 era (from the date of publication to 31 January 2020) and a COVID-19 era (from 1 February 2020 to 31 January 2021). The decision to limit the pre-COVID-19 era to the month of January 2020 relates to the identification of the first European cases of COVID-19, dating back to that period. The data were searched, extrapolated and processed with Google Analytics, which, using adaptive formulas on the data captured by the software, enabled the analysis of metrics such as: the number of visits to the site (sessions, number of users, average session duration), user behaviour (pages viewed, bounce rate, organic search) and the session acquisition path (direct traffic, referrals and social traffic). The description of the macrocategories and metrics considered in the analysis (glossary) is shown in Table 1 . An ad-hoc electronic form was drawn up to collect the main environmental variables using Excel (Microsoft Office, Microsoft Corporation, Redmond, WA, USA). Qualitative and normally distributed quantitative variables were summarised with absolute (relative) frequencies and means. The statistical differences of means between the two periods were evaluated applying the paired t-test. A two-tailed p-value less than 0.05 was considered to be statistically significant. The statistical computations were performed using STATA 16 (StatCorp., Austin, TX, USA). The During the study period (8 May 2013-31 January 2021), almost 4.4 million users accessed the portal and almost 18% of these visited the site more than once. In total, the site pages received more than 8.5 million views, with an average session duration of 50 s ( Table 1 ). In socio-demographic terms, most users came from Italy (95.98%). The site was accessed from abroad-most users came from Switzerland (0.69%), the UK (0.49%), Germany (0.48%) the USA (0.41%) and (1.95%) from 110 other countries. In Italy, the highest number of reported visits to the portal came from Rome (18.5%), Milan (18.2), Naples (3.8%), Turin (3.3%) and Florence (3.1%). Mobile phones were the most commonly used device to access the portal (62.7%), while personal computers (PCs) and tablets accounted for 30.9% and 6.4%, respectively. Most visitors (80.8%) accessed the site via an Organic search, 13.6% via Direct, 3.6% via Referral and 2.5% through social networks (mainly Facebook) ( Table 1) . As far as visits to specific web pages are concerned, the most visited pages were those regarding the Immunisation schedule and those dealing with the most common fake news about vaccines (approximately 2500 visits each). The metrics recorded by the VaccinarSì website per single day, over the pre-COVID-19 era vs. COVID-19 era (366 days) are shown in Figure 1 . A general decrease in the number of users was observed during the period under consideration. With regards visits to the website, the number of sessions decreased by 6%, whereas the number of users remained almost unchanged. Regarding the behaviour of users during the same period, there was an increase of 8% recorded for organic traffic while web page visits decreased by 24%. This reduction was particularly noticeable when considering the metrics relating to the acquisition of direct, referral and social sessions, for which the number of visits per day fell by 50%, 63% and 80%, respectively. With regards the devices used to access the site, as compared to the pre-COVID-19 period, during the COVID-19 period, there was an increase of 18% in the use of mobile phones/day (1386 visits/day in the COVID-19 period vs. 1174 visits/day pre-COVID-19) and a reduction of 37% in the use of Personal Computers (393 visits/day in the COVID-19 era vs. 623 accesses/day pre-COVID-19). A general decrease in the number of users was observed during the period under consideration. With regards visits to the website, the number of sessions decreased by 6%, whereas the number of users remained almost unchanged. Regarding the behaviour of users during the same period, there was an increase of 8% recorded for organic traffic while web page visits decreased by 24%. This reduction was particularly noticeable when considering the metrics relating to the acquisition of direct, referral and social sessions, for which the number of visits per day fell by 50%, 63% and 80%, respectively. With regards the devices used to access the site, as compared to the pre-COVID-19 period, during the COVID-19 period, there was an increase of 18% in the use of mobile phones/day (1,386 visits/day in the COVID-19 period vs. 1,174 visits/day pre-COVID-19) and a reduction of 37% in the use of Personal Computers (393 visits/day in the COVID-19 era vs. 623 accesses/day pre-COVID-19). The metrics for the websites of the VaccinarSì network in the period dating from each portal's publication until 31 January 2021 are reported in Table 2 . Similarly, for each network's web portals, the metrics recorded in the pre-COVID period (from the publication date until 31 January 2020), in the COVID-19 period (from 1 February 2020 to 31 January 2021) and the total are indicated. The metrics for the websites of the VaccinarSì network in the period dating from each portal's publication until 31 January 2021 are reported in Table 2 . Similarly, for each network's web portals, the metrics recorded in the pre-COVID period (from the publication date until 31 January 2020), in the COVID-19 period (from 1 February 2020 to 31 January 2021) and the total are indicated. With regards to the VaccinarSì Network, a comparison of the total values recorded in the pre-COVID-19 era and during the COVID-19 era showed an overall increase in the following metrics-(i) bounce rate (81.58% in COVID-19 period vs. 79.79% pre-COVID-19; (ii) organic search (88.85% in COVID-19 period vs. 79.80% pre-COVID-19); and (iii) mobile device usage (73.71% in COVID-19 period vs. 61.50% pre-COVID-19). On the other hand, a decrease in the recorded values was observed in relation to-(iv) direct, referral and social acquisition paths and (v) PC and tablet use. In particular, the increase of the organic search path, to the detriment of the referral and social paths, was observed for 9 of the 12 websites. The differences in session, user and pageview metrics in the COVID-19 period as compared to the pre-COVID-19 period are shown in Figure 2 . pre-COVID-19). On the other hand, a decrease in the recorded values was observed in relation to-(iv) direct, referral and social acquisition paths and (v) PC and tablet use. In particular, the increase of the organic search path, to the detriment of the referral and social paths, was observed for 9 of the 12 websites. The differences in session, user and pageview metrics in the COVID-19 period as compared to the pre-COVID-19 period are shown in Figure 2 . From Figure 2 it can be seen that all regional sites recorded an increase in the metrics in question (range between +41.5% and +498%), with the highest values for the number of users (from +51.6% to +498.1%) with an exception for the number of pageviews on the vaccinarsintrentino.org website, which showed a decrease of 13.8% in the COVID-19 period. Table 3 shows the statistical differences found in the number of sections, users and pages registered per day, during the pre-COVID-19 and COVID-19 era.

From Figure 2 it can be seen that all regional sites recorded an increase in the metrics in question (range between +41.5% and +498%), with the highest values for the number of users (from +51.6% to +498.1%) with an exception for the number of pageviews on the vaccinarsintrentino.org website, which showed a decrease of 13.8% in the COVID-19 period. Table 3 shows the statistical differences found in the number of sections, users and pages registered per day, during the pre-COVID-19 and COVID-19 era. Tuscany 60 248 47 212 96 407 Sicily 51 161 40 140 83 277 Sardinia 49 96 37 84 102 172 Liguria 19 45 16 40 30 67 Campania 60 214 49 183 89 394 Latium 101 198 84 174 156 293 Marche 45 121 33 96 80 193 Trentino 18 30 11 24 86 74 In particular, as far as all the websites of the VaccinarSì network are concerned, the paired t-test performed showed a significant statistical difference in the number of sections, users and pages registered during the pre-COVID-19 and COVID-19 eras. This increased consultation of the regional websites corresponds to a slight decrease in the number of sessions and pages viewed on the national website. The average consultation time appears to have decreased over the last year for all websites in the network. The average consultation time of the sessions in relation to the lifespan of each website is shown in Figure 3 (the ordinate shows the consultation time during the era of COVID- 19 while the x-axis shows the websites' lifespan). This increased consultation of the regional websites corresponds to a slight decrease in the number of sessions and pages viewed on the national website. The average consultation time appears to have decreased over the last year for all websites in the network. The average consultation time of the sessions in relation to the lifespan of each website is shown in Figure 3 (the ordinate shows the consultation time during the era of COVID-19 while the x-axis shows the websites' lifespan). − The graph shows that the average consultation time decreased in a quadratic manner in accordance with the website's age. The sites with the shortest lifespan have the longest session duration (e.g., www.vaccinarsintrentino.org with 0:01:32 min of consultation time). Web-based vaccination content is not always well-regulated and the spread of erroneous and misleading information cannot be limited or monitored [37] [38] [39] . Many young people and families rely on the information available on the Internet when choosing whether to adhere to vaccination programmes. Using the Internet to inform the population about the importance of vaccinations is a strategic tool for Public Health. As such, the aim of the VaccinarSì project was to provide in-depth online information by strategically exploiting modern ICT and e-Health [32, 37] . In these years of activity, the website has promoted the culture of preventive vaccination, constantly expanding the user-base with clicks to the site coming from over 100 countries. The views originating from outside Italy might stem from the website's inclusion in the 53 web portals of the Vaccine Safety Net network, also increasing its visibility on the international scene [40, 41] . From a careful observation of the metrics recorded per day in the pre-COVID-19 and COVID-19 eras, we can see that, while on the one hand, the VaccinarSì website showed a decreasing trend with regards pageviews, on the other hand, the network showed an increase. Indeed, some regional web portals saw their number of visits triple. This phenomenon also reflects the Italian regions' autonomy of management, with regards to the anti-COVID-19 vaccination plan implemented in Italy. The graph shows that the average consultation time decreased in a quadratic manner in accordance with the website's age.

Indeed, some regional web portals saw their number of visits triple. This phenomenon also reflects the Italian regions' autonomy of management, with regards to the anti-COVID-19 vaccination plan implemented in Italy. According to Zhao et al., the isolation imposed during the pandemic led to an increase in the use of digital social platforms to look up information [16, 17] . This is also evident from our observations, as for both the national and regional portals, there was an increase in the use of mobile devices as compared to desktop ones. As far as user behaviour is concerned, an increase in organic traffic was observed in the period under consideration, to the detriment of the referral and social paths of acquisition. This phenomenon, which was found in 9 out of 13 sites, confirmed the network as a preferred tool for direct search to acquire information on health, mainly on vaccines. The network's strength is the publication of evidence-based topics, with a particular focus on local and regional information. Moreover, considering the number of sessions, users and pages recorded by the VaccinarSì network, there were differences regarding daily visits to the site (i.e., sessions and users) and user behaviour (i.e., pages viewed). In the COVID-19 period as compared to the pre-COVID-19 period, we can see statistically significant differences, with an increasing trend for all regional websites, with an exception of the number of pages viewed on vaccinarsintrentino.org as well as for the national site. These data are difficult to interpret in light of the short pre-COVID-19 lifespan of the Trentino regional website and the instability of the statistics calculated. In contrast, for the VaccinarSì website (which has the longest pre-COVID-19 lifespan), a reduction in the number of pages consulted was observed. This may be linked to the fact that users may be more interested in the News items published rather than in the site's other previously known pages (the Science and Knowledge section, which is common to all of the portal's websites). Finally, with regards to the average session duration in relation to each web site's lifespan, our results show that with newer sites (e.g., vaccinarsintrentino.org) users spent a longer time browsing the portal than they do with older sites (e.g., www.vaccinarsi.org). This could be related to the users' level of confidence with each individual web site; indeed, a medical and scientific information site on vaccinations known to the population by virtue of its age requires less consultation time than a site with similar contents but more recently published. The results of our study might imply an effect of the phenomenon of emotional epidemiology, which affected the entire population in the COVID-19-era. Indeed, in the early stages of a pandemic, the public was keen to seek relevant knowledge and information online to meet their protection needs [42, 43] . This phenomenon, together with the social isolation imposed as a measures to contain the spread of SARS-CoV-2, may have led to an exacerbated use of ICT. Thus, the increase in our metrics may also depend on this. Nevertheless, the average time of consultation and the number of pages viewed by users are useful indicators of positive feedback and community loyalty to the VaccinarSì network. The ICT have become an integral part of our everyday lives and the development of modern ICT has given a further push towards digital consumption [1, 2] . Given technology's potential in information-seeking processes, the use of online channels by healthcare institutions is a valuable tool for the dissemination of medical and scientific knowledge to patients. In this context, recently published protocols [13] [14] [15] 19, 20, 22, 23] and systematic literature reviews describe the importance of e-Health applied to certain healthcare contexts [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] . In particular, these describe how the use of online channels, instant messaging (SMS) or Short-Messages sent via apps to communicate with patients can-(i) facilitate user participation by increasing the attendance rate for health appointments [13] ; (ii) tackle the misinformation prevailing on the web; (iii) improve therapeutic compliance [27] [28] [29] [30] [31] ; and (iv) provide remote psychological support in patients with particular clinical conditions [31, 32] . Conversely, digital communication tools in Public Health can act as a channel for incorrect and misleading information [36] [37] [38] [39] . In line with what has already been described in the literature, the results of the VaccinarSì Network Project highlight, in particular in the current pandemic context, the need to invest in health literacy by making full use of the potential offered by ICT. Our study aimed to highlight how uniting disciplines such as health education and digital communication may well be the best strategy to support citizens, by enabling them to independently, responsibly and consciously choose whether to voluntarily adhere to vaccination programs [16, 40] . In fact, the transfer of shared knowledge and skills through institutional websites, with dedicated sections, periodic news and scientific publications made available, aims to build each user's critical knowledge, thereby making each individual an active part of an extended community (empowered organisation) in continuous growth, and paving the way for increased evidence and experience-based knowledge [17, 42] . In our study, the result of the active empowerment process is clear to see, above all from the user-loyalty which serves to measure impact on the community and user satisfaction. In fact, with a 90% increase in the volume of online conversations following requests for information through virtual consultancy help-desks (especially in the COVID-19-era), the services provided by the network have become increasingly well-known, and the project's impact in terms of improving compliance and citizens' awareness has grown. Gaps such as the lack of adequate educational methods in the health sector along with the presence of misleading information content on the web, contribute to altering perceptions of health risk and increasing improper spreading of information, especially with regards to the topic of vaccinations. On the contrary, proper sharing of verified scientific content and health communication via mass media, provides users with the necessary tools to make informed health decisions. At the same time, it gives them the chance to become autonomous in searching and disseminating reliable information [16] [17] [18] 44] . In this context, features such as total views, pageviews, bounce rate and time spent on a specific landing page, are useful cyber information indicators. In our study, these demonstrate the importance of digital vaccine communication initiatives such as a support for users, operators and the community. In this context, a key role is played by the active cooperation between the media and scientific professionals (experts in public health, infectious diseases and epidemiology), who, in collaboration with local doctors (general practitioners and paediatricians) could constitute an effective network in identifying and 'unmasking' disinformation, by providing the public with simple and relevant sources of up-to-date information. The future use of these digital tools to disseminate reliable information, represents an opportunity for the transfer of evidence-based knowledge for users and health professionals, in order to achieve the empowerment of the population for informed health choices. The VaccinarSì Network's goal for the future is to grow further to reach an even wider audience and take advantage of further collaborations with national and international scientific organisations and associations, to further promote the culture of prevention and vaccination.
