COVID-19 Vaccination Intent and Belief that Vaccination Will End the Pandemic.

High vaccination coverage is considered to be key in dealing with the coronavirus disease (COVID-19) pandemic. However, vaccine hesitancy can limit uptake. We examined the specific coronavirus beliefs that persons have regarding COVID-19 and COVID-19 vaccines and to what extent these beliefs explain COVID-19 vaccination intentions. We conducted a survey among 4,033 residents of the Netherlands that examined COVID-19 vaccination intentions and various beliefs. Random forest regression analysis explained 76% of the variance in vaccination intentions. The strongest determinant in the model was the belief the COVID-19 crisis will only end if many persons get vaccinated. Other strong determinants were beliefs about safety of vaccines, specifically in relation to vaccine development and approval process; (social) benefits of vaccination; social norms regarding vaccination behavior; and effectiveness of vaccines. We propose to address these specific beliefs in communications about COVID-19 vaccinations to stimulate vaccine uptake.

Dynamics in public perceptions and media coverage during an ongoing outbreak of meningococcal W disease in the Netherlands.

BACKGROUND: From 2015 to 2018, the Netherlands faced an outbreak of invasive meningococcal disease (IMD) caused by serogroup W. To counter the rise in infections, the government introduced a catch-up menACWY vaccination campaign for teenagers in 2018 and 2019. The outbreak situation induced substantial media attention and a run on menACWY vaccines outside the vaccination campaign. This study aimed to gain insights into the dynamics of public perceptions of and responses to the outbreak and the menACWY vaccination, and into the media coverage about the outbreak. METHODS: Three repeated surveys (N = 1110) between 2017 and 2019 were sent to parents of teenagers invited for a menACWY catch-up vaccination, other parents, and individuals with no under-age children. These surveys assessed IMD risk perceptions, attitudes towards the menACWY vaccination, trust in involved institutions, and willingness to vaccinate with the menACWY vaccine. Changes in the public perceptions and responses were studied with linear multilevel regression analyses. In addition, 103 national newspaper articles from the period 2017-2019 were thematically coded with themes about IMD and the menACWY vaccination. RESULTS: The survey results showed clear increases in perceived IMD severity, positive attitude towards the menACWY vaccination, and willingness to vaccinate over time. Perceived IMD vulnerability remained low across all three waves, and trust in involved institutions increased slightly. Differences between the survey groups were limited. The newspaper articles discussed the rise in infections extensively, the disease symptoms, and the possible fatal outcome of IMD. In addition, while many articles discussed the menACWY vaccine shortage, few discussed the safety or effectiveness of the vaccine. CONCLUSION: The real-time insights into the interrelated dynamics of public perceptions, responses, and media coverage provide an integrated portrait of the social developments during this outbreak. The focus on IMD severity and the absence of doubt in the public discussion about vaccine safety may have played an important role in the societal response to this outbreak and the recommended vaccine.

Dynamic Public Perceptions of the Coronavirus Disease Crisis, the Netherlands, 2020.

A key component of outbreak control is monitoring public perceptions and public response. To determine public perceptions and public responses during the first 3 months of the coronavirus disease (COVID-19) outbreak in the Netherlands, we conducted 6 repeated surveys of ≈3,000 persons. Generalized estimating equations analyses revealed changes over time as well as differences between groups at low and high risk. Overall, respondents perceived the risks associated with COVID-19 to be considerable, were positive about the mitigation measures, trusted the information and the measures from authorities, and adopted protective measures. Substantial increases were observed in risk perceptions and self-reported protective behavior in the first weeks of the outbreak. Individual differences were based mainly on participants' age and health condition. We recommend that authorities constantly adjust their COVID-19 communication and mitigation strategies to fit public perceptions and public responses and that they tailor the information for different groups.

Information needs during an emerging outbreak of meningococcal W135 disease in the Netherlands: a study among teenagers, their parents and healthcare professionals.

BACKGROUND: To counter the rise in invasive meningococcal disease (IMD) serogroup W, the Netherlands introduced a menACWY catch-up vaccination campaign for teenagers in 2018 and 2019. Teenagers and parents who have questions or who seek advice from a professional about vaccinations are likely to consult a youth healthcare professional or their general practitioner. This study aimed to appraise the ability of these healthcare professionals to meet the information needs of teenagers and their parents at the start of the vaccination campaign. METHODS: With online surveys, we assessed information needs in teenagers (N = 1603) and parents (N = 1784) concerning IMD and the menACWY vaccination, and in healthcare professionals (N = 520) in their communication with teenagers and parents. We additionally studied healthcare professionals' expectations of the information needs of teenagers and parents. RESULTS: We identified several information needs about IMD and the menACWY vaccination in teenagers, parents and healthcare professionals. Some important commonalities in the information needs in these three groups were found, with regard to the topics IMD prevention, vaccine effectiveness and vaccine protection duration. Healthcare professionals' expectations of the information needs of teenagers and parents were quite accurate but some important discrepancies were found. CONCLUSION: Our results suggest that healthcare professionals might not have been optimally equipped or prepared for questions from teenagers and their parents at the beginning of the vaccination campaign. We recommend public health institutes to timely assess and meet information needs about new vaccines in healthcare professionals to optimally equip them for consultations.

The role of the media in the amplification of a contested health risk: Rubber granulate on sport fields.

This study aims to increase insights into the potential role of the media in the amplification and attenuation of modern risks in society, by studying the dynamics and contents of the newspaper coverage about the potential health risk posed by rubber granulate in the Netherlands. We thematically analysed 153 national newspaper articles about the risks posed by rubber granulate between September 2016 and February 2017. Our results suggest that newspaper coverage might have contributed to heightened public risk perceptions by presenting the negligible health risk as uncertain, focusing on controversy between authorities and experts, describing responses such as concerns, commotion, and adopted risk mitigation measures by members of the public, and by providing insufficient contextualization on whether hazardous substances in rubber granulate pose a threat to health. The risks posed by rubber granulate is one of the many modern risks that has become subject to heated and mediated public discussions. Our results provide in-depth insights into important content elements in media coverage during such discussions and the impact of these elements on public perceptions. Public health institutes and other authorities might be able to mitigate the amplification of risks through media coverage by means of appropriate preparedness and response.

Meningococcal W135 Disease Vaccination Intent, the Netherlands, 2018-2019.

To control the rise in Neisseria meningitidis strain W infections, during 2018-2019, the Netherlands launched a catch-up meningococcal conjugate (MenACWY) vaccination campaign for teenagers (13-18 years of age). Applying a mental models approach, we surveyed teenagers and their parents about their knowledge and beliefs about meningococcal disease, the MenACWY vaccination, vaccinations in general, and their MenACWY vaccination intentions. Using random forest analysis, we studied predictions of vaccination intentions by knowledge and beliefs. Survey response rate was 52.8% among teenagers and 59.4% among parents. MenACWY vaccination intentions were best predicted by knowledge and beliefs about vaccinations in general, surpassing knowledge and beliefs about meningococcal disease and the MenACWY vaccination. For teenagers, their parents' intention that the teenager be vaccinated was a strong predictor of the teenagers' own vaccination intention. To optimize vaccination uptake during future outbreaks, we recommend that communications emphasize the effectiveness and safety of vaccines and continue to focus on parents.

Collaborative emergency preparedness and response to cross-institutional outbreaks of multidrug-resistant organisms: a scenario-based approach in two regions of the Netherlands.

BACKGROUND: The likelihood of large-scale outbreaks of multidrug-resistant organisms (MDRO) is growing. MDRO outbreaks can affect a wide range of healthcare institutions. Control of such outbreaks requires structured collaboration between professionals from all involved healthcare institutions, but guidelines for cross-institutional procedures are, however, often missing. Literature indicates that such multi-actor collaboration is most promising when effective network brokers are present, and when the collaborative actors have clarity about the different roles and responsibilities in the outbreak response network, including collaborative structures and coordination roles. Studying these factors in an imaginary MDRO outbreak scenario, we gained insights into the expectations that health professionals in the Netherlands have in regard to the procedures required to best respond to any future cross-institutional MDRO outbreaks. METHODS: For exploration purpose, a focus group discussion with ten healthcare professionals was held. Subsequently, an online-survey was conducted among 56 healthcare professionals in two Dutch regions. The survey data was analysed using social network analyses (clique analysis and centrality analysis), which provided insights into the collaborative structures and potential brokers in the outbreak response networks. Additionally, respondents were asked which healthcare institutions and which professions they would prefer as coordinating actors in the collaborative network. RESULTS: Our results show a relatively high level of perceived clarity about the roles and responsibilities that healthcare professionals have during a joint outbreak response. The regional outbreak response networks which were studied appeared inclusive and integrated, with many overlapping groups of fully-connected healthcare actors. Social network analyses resulted in the identification of several central actors from different healthcare institutions with the potential to take on a brokerage role in the collaboration. Actors in the outbreak response networks also showed to prefer several healthcare professionals to take on the coordination roles. CONCLUSION: Expected collaborative structures during an imaginary regional MDRO outbreak response are relatively dense and integrated. In regard to the coordination of an MDRO outbreak response, based on both the network analysis results and the preferred coordination roles, our findings support a governance structure with several healthcare institutions involved in responding to future cross-institutional MDRO outbreaks.

Parental intention, attitudes, beliefs, trust and deliberation towards childhood vaccination in the Netherlands in 2022: Indications of change compared to 2013.

BACKGROUND: Vaccine uptake within the Dutch National Immunisation Programme (NIP) has slightly declined since the COVID-19 pandemic. We studied psychosocial factors of vaccine uptake, namely parental intention, attitudes, beliefs, trust and deliberation (i.e., self-evidence), before (2013) and two years into the pandemic (2022). METHODS: In 2022 and 2013, parents with a young child (aged < 3.5 years) participated in online surveys on vaccination (n = 1000 and 800, (estimated) response = 12.2 % and 37.2 %, respectively). Psychosocial factors were measured on 7-point Likert scales. Multivariate logistic regression analysis was used to study differences between parents in 2022 and 2013 in 'negative' scores (≤2) of psychosocial factors. RESULTS: In both 2022 and 2013, most parents with a young child expressed positive intention (2022 = 83.1 %, 2013 = 87.0 %), attitudes (3 items: 2022 = 66.7 %-70.9 %, 2013 = 62.1 %-69.8 %) and trust (2022 = 51.8 %, 2013 = 52.0 %) towards the NIP and considered vaccinating their child as self-evident (2022 = 57.2 %, 2013 = 67.3 %). Compared to parents in 2013, parents in 2022 had significantly higher odds of reporting negative attitudes towards vaccination (3 items combined: OR = 2.84, 95 % CI = 1.09, 7.37), believing that vaccinations offer insufficient protection (OR = 4.89, 95 % CI = 3.19, 7.51), that the NIP is not beneficial for the protection of their child's health (OR = 2.23, 95 % CI = 1.15, 4.35), that vaccinating their child does not necessarily protect the health of other children (OR = 2.24, 95 % CI = 1.16, 4.33) or adults (OR = 2.22, 95 % CI = 1.32, 3.75) and that vaccinations could cause severe side effects (OR = 2.20, 95 % CI = 1.35, 3.58), preferring natural infection over vaccination (OR = 3.18, 95 % CI = 2.24, 4.51) and reporting low trust towards the NIP (OR = 1.73, 95 % CI = 1.08, 2.79). CONCLUSIONS: Although most parents had positive intention, attitudes and trust towards vaccination and perceived vaccinating their child as self-evident, proportions of parents with negative scores were slightly larger in 2022 compared to 2013. Monitoring these determinants of vaccine uptake and developing appropriate interventions could contribute to sustaining high vaccine uptake.

The public's considerations about implementing non-pharmaceutical interventions to manage a novel COVID-19 epidemic.

In the future, new variants of the SARS-CoV-2 virus might emerge and cause outbreaks. If this occurs, the implementation of non-pharmaceutical interventions (NPIs) can be reconsidered. Consideration of the potential benefits and harms of implementing NPIs, and ultimately deciding about implementing NPIs, is currently mainly executed by experts and governments. However, general literature on public engagement suggests that integrating public perspectives into decision-making can enhance the quality of decisions and foster greater public understanding of them. In this study, a deliberative mini-public was conducted to integrate this public perspective. The aim was to elicit public considerations regarding non-pharmaceutical interventions by asking a diverse group of citizens to participate as decision-makers and convene, learn and deliberate about implementing non-pharmaceutical interventions during a hypothetical outbreak of a new SARS-CoV-2 variant. Participants emphasized the importance of early implementation during the outbreak, to prevent exceeding healthcare capacity, long-term mental health issues, educational deficits, and bankruptcies. Additionally, participants stressed taking public support into account, and shared ideas on maintaining support. Furthermore, participants wanted to give citizens personal responsibility and freedom in making their own assessment regarding adherence to interventions and how much risk of infection they would be willing to accept. Participants also expressed the need for the government to adopt a learning attitude towards improvements in pandemic response, and to generate more focus on long-term strategies. The deliberative mini-public, revealed public considerations that reflected public values and needs. These considerations might be helpful in better aligning epidemic management policies with public perspectives. Regarding the deliberative mini-public, uncertainties remain about the design and impact on a bigger scale.

Environmental impact assessment of vegetable production in West Java, Indonesia.

Indonesia is one of the world's economies contributing the most to greenhouse gas (GHG) emissions from the global food system. This study aimed to quantify the environmental impacts of Indonesian vegetable production and the relative contribution of different farm inputs. Data were collected from 322 vegetable farms in the Lembang sub-district in West Java. A Life Cycle Assessment (LCA) was carried out to estimate global warming potential (GWP), acidification potential (AP), freshwater eutrophication potential (EP), and abiotic resource depletion. Results of the LCA showed that GHG emissions were 14.1 t CO2eq ha-1 yr-1 (0.5 t CO2eq t-1), AP was 39.3 kg SO2eq ha-1 yr-1 (1.4 kg SO2eq t-1), EP was 45.3 kg PO4eq ha-1 yr-1 (1.7 kg PO4eq,), and depletion of phosphate, potash, and fossil fuel resources were 60.0 kg P2O5, 101 kg K2O, and 6299 MJ ha-1 yr-1, respectively (1.9 kg P2O5, 3.7 kg K2O, and 281 MJ t-1). Organic fertilizer use contributed the most to impact categories of global warming, freshwater eutrophication, and acidification, followed by synthetic fertilizer. The sensitivity analysis showed that yield and organic fertilizer use explained most of the variation in GHG emission per ton product. Therefore, it is recommended to include organic fertilizer use in the fertilizer advisory system for vegetable production in Indonesia.

Preferences for public engagement in decision-making regarding four COVID-19 non-pharmaceutical interventions in the Netherlands: A survey study.

BACKGROUND: Worldwide, non-pharmaceutical interventions (NPIs) were implemented during the COVID-19 crisis, which heavily impacted the daily lives of citizens. This study considers public perspectives on whether and how public engagement (PE) can contribute to future decision-making about NPIs. METHODS: An online survey was conducted among a representative sample of the public in the Netherlands from 27 October to 9 November 2021. Perceptions and preferences about PE in decision-making on NPIs to control COVID-19 were collected. Preferences regarding four NPIs were studied: Nightly curfew (NC); Digital Covid Certificate (DCC); Closure of elementary schools and daycares (CED); and physical distancing (1.5M). Engagement was surveyed based on the five participation modes of the IAP2 Spectrum of Public Participation, namely inform, consult, advice, collaborate and empower. RESULTS: Of the 4981 respondents, 25% expressed a desire to engage in decision-making, as they thought engagement could improve their understanding and the quality of NPIs, as well as increase their trust in the government. Especially for the NPIs DCC and NC, respondents found it valuable to engage and provide their perspective on trade-offs in values (e.g. opening up society versus division in society by vaccination status). Respondents agreed that the main responsibility in decision-making should stay with experts and policy-makers. 50% of respondents did not want to engage, as they felt no need to engage or considered themselves insufficiently knowledgeable. Inform was deemed the most preferred mode of engagement, and empower the least preferred mode of engagement. CONCLUSION: We reveal large variations in public preferences regarding engagement in NPI decision-making. With 25% of respondents expressing an explicit desire to engage, and considering the benefit of PE in other areas of (public) health, opportunities for PE in NPI decision-making might have been overlooked during the COVID-19 pandemic. Our results provide guidance into when and how to execute PE in future outbreaks.

Did the temporary suspension of Vaxzveria vaccinations influence COVID-19 vaccination intentions, vaccination perceptions and trust in the vaccination campaign? A repeated survey study in the Netherlands.

In spring 2021, several countries, among which the Netherlands, suspended vaccinations against COVID-19 with the Vaxzevria vaccine from AstraZeneca after reports of rare but severe adverse events. This study investigates the influence of this suspension on the Dutch public's perceptions of COVID-19 vaccinations, trust in the government's vaccination campaign, and COVID-19 vaccination intentions. We conducted two surveys in a population of general Dutch public (18 + ), one shortly before the pause of AstraZeneca vaccinations and one shortly thereafter (N eligible for analysis = 2628). Our results suggest no changes in perceptions nor intentions regarding the COVID-19 vaccines in general but do suggest a decline in trust in the government's vaccination campaign. In addition, after the suspension, perceptions of the AstraZeneca vaccines were more negative in comparison to those of COVID-19 vaccinations in general. AstraZeneca vaccination intentions were also considerably lower. These results stress the need to adapt vaccination policies to anticipated public perceptions and responses following a vaccine safety scare, as well as the importance of informing citizens about the possibility of very rare adverse events prior to the introduction of novel vaccines.

Voices of society: the emergence of civil-society practices aiming to engage in the management of the COVID-19 pandemic in the Netherlands.

During the COVID-19 pandemic, public groups mobilised themselves in civil-society engagement practices (CSEPs) aiming to improve or suggest alternative epidemic management. This study explores the motivation to establish CSEPs and their perceived contributions to epidemic management, to gain insight whether integrating views of CSEPs could add value. A systematic online search was executed to identify CSEPs focused on COVID-19 management between January 2020 and January 2022 in the Netherlands. In order to create a comprehensible overview of the identified CSEPs, relevant characteristics were gathered and mapped, for example, local or national scope, subject of action and goals. A selection of CSEPs was interviewed between April and June 2022 to study their motivators to start the CSEPs and perceived contributions to management. The search resulted in the identification of 22 CSEPs, of which members of 14 CSEPs were interviewed. These members indicated several issues that motivated the start of their CSEP, namely; shortage of equipment, sense of solidarity, and a perceived lack of governmental action, lack of democratic values and lack in diversity of perspectives in epidemic management. All respondents believed to have contributed to policy or society, by influencing opinions, and occasionally by altering policy. However, respondents encountered obstacles in their attempts to contribute such as inability to establish contact with authorities, feeling unheard or undermined, and complications due to the interplay of political interests. In conclusion, CSEPs have fulfilled various roles such as providing alternative management policies, producing equipment, representing the needs of vulnerable populations, and supporting citizens and providing citizens with other viewpoints and information. The identified motivators to establish CSEPs in this study uncover room for improvements in policy. These insights, together with the identified perceived barriers of CSEPs, can be used to improve the connection between (future) epidemic management and public priorities and interests.

Public Perceptions of Contentious Risk: The Case of Rubber Granulate in the Netherlands.

This paper reports on the perceptions of risk related to practicing sports on fields containing rubber granulate infill, and preferences for mitigation measures, among people with and without offspring exposed to rubber granulate. Two repeated surveys were conducted among members of the general population and parents of children aged under 18, in the middle of a dynamic public discussion about the potential health risks of exposure to rubber granulate. The first survey (N = 1033) was administered in December 2016 at a time characterized by considerable public uncertainty and contrasting opinions in the public risk debate. The second survey (N = 782) was conducted in January 2017 after the publication of a risk assessment report, which concluded that practicing sport on fields containing rubber granulate is safe. Multilevel analyses were performed to study changes in perceptions of risk and mitigation preferences in the time between the two surveys, the influence of being familiar with new information following the risk assessment report, and the differences in the perceptions of risk and mitigation preferences between groups with and without offspring exposed to rubber granulate. The results of this study show that, initially, a substantial proportion of the Dutch public perceived practicing sports on fields containing rubber granulate as a potential health threat to children. Over time, after publication of a new risk assessment study stating that practicing sports on fields containing rubber granulate is safe, perceived risk and preferences for mitigation of this risk decreased, especially among those who were familiar with the new information. Parents of children under the age of 18, in particular those with children who were exposed to rubber granulate, were more likely to perceive the risk as higher and to prefer a stricter mitigation policy. These insights may be important to inform public health communication strategies with respect to the timing and tailoring of risk messages to various groups.
