Population Attributable Fraction of Nonvaccination of COVID-19 Due to Vaccine Hesitancy, United States, 2021.

Understanding the extent of coronavirus disease 2019 (COVID-19) nonvaccination attributable to vaccine hesitancy versus other barriers can help prioritize approaches for increasing vaccination uptake. Using data from the Centers for Disease Control and Prevention's Research and Development Survey, a nationally representative survey fielded from May 1 to June 30, 2021 (n = 5,458), we examined the adjusted population attribution fraction (PAF) of COVID-19 vaccine hesitancy attributed to nonvaccination according to sociodemographic characteristics and health-related variables. Overall, the adjusted PAF of nonvaccination attributed to vaccine hesitancy was 76.1%. The PAF was highest among adults who were ≥50 years of age (87.9%), were non-Hispanic White (83.7%), had a bachelor's degree or higher (82.7%), had an annual household income of at least $75,000 (85.5%), were insured (82.4%), and had a usual place for health care (80.7%). The PAF was lower for those who were current smokers (65.3%) compared with never smokers (77.9%), those who had anxiety or depression (65.2%) compared with those who did not (80.1%), and those who had a disability (64.5%) compared with those who did not (79.2%). Disparities in PAF suggest areas for prioritization of efforts for intervention and development of messaging campaigns that address all barriers to uptake, including hesitancy and access, to advance health equity and protect individuals from COVID-19.

Mapping sociodemographic and geographical differences in human papillomavirus non-vaccination among young girls in Sweden.

AIMS: Human papillomavirus (HPV) vaccination plays a key role in the prevention of cervical cancer. Yet, disparities in HPV vaccination in Sweden have persisted. Previous research on such disparities has typically focused on singular sociodemographic variables and measures of average risk. Using a multi-categorical approach and drawing on intersectionality theory, this study aimed to provide a more precise mapping of HPV non-vaccination among girls in different sociodemographic groups and geographical areas in Sweden during 2013-2020. METHODS: Using nationwide register data, we conducted a multi-categorical analysis of individual heterogeneity and discriminatory accuracy complemented by a multilevel geographical analysis. We mapped HPV non-vaccination prevalence across 54 strata defined by parental income, education and country of birth, and urban versus rural place of residence. We also disentangled municipal and regional influences on HPV non-vaccination. RESULTS: HPV non-vaccination was more common in groups with a low income, a low education and an immigration background, whereas among those with an immigration background, the association between income, education and HPV non-vaccination was more complex. Geographical differences were found between municipalities. However, the discriminatory accuracy of the sociodemographic and geographical groups was weak, and 50% of the non-vaccination cases were observed in eight strata, of which some are among those with low risk. CONCLUSIONS: Our findings underscore the importance of universal yet tailored approaches, including providing adequate information about HPV vaccination in Swedish and other languages, and of health-care professionals displaying sensitivity to patients' and parents' questions or needs.

Suboptimal COVID-19 vaccine uptake among hospitalised patients: an opportunity to improve vulnerable, hard-to-reach population vaccine rates.

BACKGROUND: COVID-19 vaccination represents a key preventative part of the Australian public health approach to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Hospital inpatients are frequently high risk for severe COVID-19 and death. Anecdotes of high-risk inpatients being unvaccinated and a lack of electronic medical record (EMR) visibility of COVID-19 vaccination status prompted the present study as these patients could represent a risk to themselves, staff, other patients and service provision. AIMS: To determine the uptake of COVID-19 vaccine among inpatients at an adult Australian tertiary public hospital and identify reasons for non-vaccination. METHODS: A point-prevalence study of patient-reported COVID-19 vaccine status was conducted on 26 October 2021 through an in-person interview with collection of demographic factors and reasons for non-vaccination. RESULTS: Of 368 (68% of inpatients) participants, 280 (76%) reported receiving at least one COVID-19 vaccine dose. Vaccination status was associated with older age, having received the flu vaccine, being born in Australia and not requiring an English-language interpreter. The majority (88%) of participants had at least one comorbid risk factor for severe COVID-19. Of the unvaccinated (n = 88), 67% were willing to be vaccinated with 54% of those indicating vaccination in hospital would be helpful and 42% requesting approval from their doctor. CONCLUSIONS: Vaccine uptake in our cohort is suboptimal. Existing public health programmes have failed to reach this high-risk, vulnerable population. Changes to the national vaccination strategy to include a parallel inhospital programme for all hospital encounters and target culturally and linguistically diverse individuals might improve uptake among this high-risk, hard-to-reach group of patients.

Susceptibility to Hepatitis A Virus Infection in the United States, 2007-2016.

BACKGROUND: Despite national immunization efforts, including universal childhood hepatitis A (HepA) vaccination recommendations in 2006, hepatitis A virus (HAV)-associated outbreaks have increased in the United States. Unvaccinated or previously uninfected persons are susceptible to HAV infection, yet the susceptibility in the US population is not well known. METHODS: Using National Health and Nutrition Examination Survey 2007-2016 data, we estimated HAV susceptibility prevalence (total HAV antibody negative) among persons aged ≥2 years. Among US-born adults aged ≥20 years, we examined prevalence, predictors, and age-adjusted trends of HAV susceptibility by sociodemographic characteristics. We assessed HAV susceptibility and self-reported nonvaccination to HepA among risk groups and the "immunization cohort" (those born in or after 2004). RESULTS: Among US-born adults aged ≥20 years, HAV susceptibility prevalence was 74.1% (95% confidence interval, 72.9-75.3%) during 2007-2016. Predictors of HAV susceptibility were age group 30-49 years, non-Hispanic white/black, 130% above the poverty level, and no health insurance. Prevalences of HAV susceptibility and nonvaccination to HepA, respectively, were 72.9% and 73.1% among persons who reported injection drug use, 67.5% and 65.2% among men who had sex with men, 55.2% and 75.1% among persons with hepatitis B or hepatitis C, and 22.6% and 25.9% among the immunization cohort. Susceptibility and nonvaccination decreased over time among the immunization cohort but remained stable among risk groups. CONCLUSIONS: During 2007-2016, approximately three-fourths of US-born adults remained HAV susceptible. Enhanced vaccination efforts are critically needed, particularly targeting adults at highest risk for HAV infection, to mitigate the current outbreaks.

Estimates and determinants of HPV non-vaccination in 14-year-old Canadians: Results from the childhood national immunization coverage survey, 2019.

Human papillomavirus (HPV) infections, the most common sexually transmitted infections, are associated with various health outcomes including anogenital warts and cancers. Despite significant investments in HPV vaccination programs, ensuring adequate vaccination coverage for adolescents remains a challenge in Canada. This analysis used data collected through the 2019 Childhood National Immunization Coverage Survey (CNICS) to determine national estimates of HPV non-vaccination and investigate determinants of HPV non-vaccination for adolescents aged 14-years old in Canada, both overall and stratified by gender. The primary outcome of interest was HPV vaccination status, categorized as vaccinated with at least one dose or unvaccinated. Simple and multiple logistic regression models were used to investigate determinants of HPV non-vaccination. In 2019, an estimated 19.8% of the 14-year-olds in Canada were unvaccinated for the HPV vaccine, with males having higher non-vaccination rates than females (27.0% compared to 12.9%). In the unstratified analysis, factors associated with HPV non-vaccination for 14-year-olds were gender and region of residence. These factors differed by gender - for males, region of residence and respondent's age were significant factors, whereas for females, total household income was a significant factor. These results could help public health officials and policymakers develop and implement tailored interventions to enhance the delivery of HPV vaccination programs for male and female adolescents. By targeting populations that are under-vaccinated, vaccine uptake could be better facilitated to help reduce inequalities in access to the HPV vaccine, which could also potentially reduce disparities in HPV-related health outcomes.

Assessing the Vaccination Status and Barriers to Influenza, Pneumococcal, and COVID-19 Vaccination Among Moroccan Patients With Chronic Inflammatory Rheumatic Disease.

OBJECTIVE: To evaluate the vaccination coverage of patients with chronic inflammatory rheumatic disease (CIRD) against influenza, pneumococcus, and COVID-19 and to determine, per the patients' point of view, the possible factors related to vaccination hesitation and/or refusal. METHODS: A cross-sectional study carried out by the vaccination working group of the Moroccan Society of Rheumatology, including patients with CIRD in Morocco. Information about vaccination coverage and reasons for non-vaccination against influenza, pneumococcal infection, and COVID-19 was collected. RESULTS: This survey included 230 patients (mean age of 46.9 +/-13.89 years; 68.7% females) affected by CIRD (rheumatoid arthritis 53%, spondyloarthritis 39.6%, psoriatic arthritis 7%). The study shows a significant lack of influenza and pneumococcal vaccination in CIRD patients, with vaccination coverage against influenza, pneumococcal infection, and COVID-19 at 2.2%, 0.4%, and 80.9%, respectively. The main reason for non-vaccination against influenza and pneumococcus was related to the absence of recommendations by their doctors (77%, 87%, p = 0.04). Additionally, the primary reason for non-vaccination against COVID-19 was the fear of the vaccine's side effects (51%, p = 0.0001), mainly a flare-up of CIRD (44%, p = 0.001). CONCLUSION: This survey shows a lack of influenza, pneumococcal, and COVID-19 vaccination in CIRD patients. The principal actions to improve vaccination should aim to educate patients and encourage rheumatologists to vaccinate their patients.

Reasons for COVID-19 Non-Vaccination from 2021 to 2023 for Adults, Adolescents, and Children.

Understanding how attitudes and beliefs about COVID-19 vaccination have changed over time is essential for identifying areas where targeted messaging and interventions can improve vaccination confidence and uptake. Using data from multiple waves of the nationally representative U.S. Census Bureau's Household Pulse Survey collected from January 2021 to May 2023, we assessed reasons for the non-vaccination of adults, adolescents, and children using the Health Belief Model as the framework for understanding behavior. Among unvaccinated adults, perceived vulnerability increased from 11.9% to 44.1%, attitudinal factors/mistrust increased from 28.6% to 53.4%, and lack of cue to action increased from 7.5% to 9.7% from January 2021 to May 2022. On the other hand, safety/efficacy concerns decreased from 74.0% to 60.9%, and logistical barriers to vaccination decreased from 9.1% to 3.4% during the same time period. Regarding reasons for non-vaccination of youth, perceived vulnerability increased from 32.8% to 40.0%, safety/efficacy concerns decreased from 73.9% to 60.4%, and lack of cue to action increased from 10.4% to 13.4% between September 2021 and May 2023. While safety/efficacy concerns and logistic barriers have decreased, increases in perceived vulnerability to COVID-19, mistrust, and lack of cues to action suggest that more efforts are needed to address these barriers to vaccination.

"Zero Dose" Children in the Democratic Republic of the Congo: How Many and Who Are They?

(1) Background: The Democratic Republic of the Congo (DRC) is one of the countries with the highest number of never vaccinated or "zero-dose" (ZD) children in the world. This study was conducted to examine the proportion of ZD children and associated factors in the DRC. (2) Methods: Child and household data from a provincial-level vaccination coverage survey conducted between November 2021-February 2021 and 2022 were used. ZD was defined as a child aged 12 to 23 months who had not received any dose of pentavalent (diphtheria-tetanus-pertussis-Haemophilus influenzae type b (Hib)-Hepatitis B) vaccine (by card or recall). The proportion of ZD children was calculated and associated factors were explored using logistic regression, taking into account the complex sampling approach. (3) Results: The study included 51,054 children. The proportion of ZD children was 19.1% (95%CI: 19.0-19.2%); ZD ranged from 62.4% in Tshopo to 2.4% in Haut Lomami. After adjustment, being ZD was associated with low level of maternal education and having a young mother/guardian (aged ≤ 19 years); religious affiliation (willful failure to disclose religious affiliation as the highest associated factor compared to being Catholic, followed by Muslims, revival/independent church, Kimbanguist, Protestant); proxies for wealth such as not having a telephone or a radio; having to pay for a vaccination card or for another immunization-related service; not being able to name any vaccine-preventable disease. A child's lack of civil registration was also associated with being ZD. (4) Conclusions: In 2021, one in five children aged 12-23 months in DRC had never been vaccinated. The factors associated with being a ZD child suggest inequalities in vaccination that must be further explored to better target appropriate interventions.

Labels matter: Use and non-use of 'anti-vax' framing in Australian media discourse 2008-2018.

Childhood vaccine refusal is a globally contentious topic, with some jurisdictions addressing it with punitive policies. Media discourse influences how solutions are framed by implying blame - a process known as framing. We examined Australian media discourse on vaccine rejection over a period in which mandatory childhood vaccination policies were discussed and introduced, focusing on the common Australian pejorative term 'anti-vaxxer'. We mapped frequency of use from January 2008 to December 2018. We then searched Factiva for print media articles on childhood vaccination and parents published in that period, searching separately for articles using and not using 'anti-vaxxer' and variants. We constructed a set of 85 articles that did, and 85 articles date-matched that did not use the term to make comparisons and conducted a frame analysis of each set. 'Anti-vaxxer' was absent in Australian media discourse 2008-2010, rising to a peak of 247 articles using the term at the height of legislative change in 2017. Parents were framed as: 1) deviant "others"; 2) ignorant and in need of informing; 3) vulnerable and in need of protection from anti-vaccination activists; 4) thoughtful, critical, informed, and in need of agency and respect; 5) entitled, privileged and selfish; and finally, 6) lacking access to vaccination, rather than being unwilling. Articles using 'anti-vax' terms were more likely to negatively characterise non-vaccinating parents, while articles not including this language were more likely to frame them as thoughtful or lacking access. This study clearly demonstrates strategic use of pejoratives in the Australian mass media around a time of pressure for legislative change and conflation of anti-vaccination activists with non-vaccinating parents. We suggest fundamental changes to how non-vaccination is framed and dealt with in the media to curb polarization and fostering more respectful dialogue, and better social and public health outcomes.

Differential determinants and reasons for the non- and partial vaccination of children among Nigerian caregivers.

BACKGROUND: Vaccination has saved millions of lives. However, the vaccination rate in Nigeria remains low. We differentiate reasons for incomplete vaccination by status: not- and partially- vaccinated, and examine the association between sociodemographic characteristics of caregivers and reasons for incomplete vaccination. METHODS: Data from the Multiple Indicator Cluster Survey (MICS) conducted in Nigeria in 2016 and 2017 was analyzed. The logistic regression was used to evaluate associations between sociodemographic characteristics of caregivers and incomplete vaccination according to different reasons. RESULTS: The most common reason for non-vaccination is that caregivers have no faith in immunization (27.0%), followed by lack of awareness of the need for immunization (26.0%) and the perception that the place where immunization is given is too far/inconvenient (24.3%). The most common reason for partial vaccination is that caregivers thought the children had already been fully immunized (44.8%), followed by the inconvenient location for immunization (15.3%) and supply-side issues such as shortage of vaccine stock and absence of vaccinators (14.4%). Among caregivers whose children are never vaccinated, a lower level of education is correlated with more likelihood of having no faith in immunization and poorer households are more likely to state a lack of awareness of the need for immunization need and an inconvenient place as the reasons for non-vaccination. Among caregivers whose children are only partially vaccinated, educated and wealthier caregivers are more likely to state that they thought their children were fully vaccinated, while poorer caregivers tend to give an inconvenient immunization place as the reason for incomplete vaccination. Supply-side barriers are not systematically correlated with educational attainment or wealth level of caregivers. CONCLUSION: Barriers to vaccination are different according to vaccination status: not- and partially- vaccinated, as is the association between sociodemographic characteristics of caregivers and reasons for incomplete vaccination. The policy to increase vaccination take-up should take these differentials into consideration.

Different Reasons for Not Completing Routine Vaccinations Among Jewish and Arab Children in Israel.

Minority communities are at high risk for low childhood vaccination coverage rates. This paper compared the rate of children not fully vaccinated and the reasons for that between Jewish (majority) and Arab (minority) children in Israel. This cross-sectional study screened the medical files of 14,232 children (12,360 Jewish and 1872 Arab), registered at Mother-Child Health Clinics in two large geographical area, to identify children who did not complete the last dose of hepatitis B and DTaP or first dose of MMR vaccines. We compared the reasons for not completing the vaccine schedule registered by the nurses between Jewish and Arab children. We identified 1052 children who did not complete at least one of the vaccines: 975 Jewish children and 77 Arab children. Four causal categories were identified: medical reasons, parental decision, parental behaviour, and organizational reasons. Multinomial logistic regression analysis was performed to analyze the reasons for not completing the vaccination protocol. Arab children compared to Jewish children were more likely not to complete the vaccination protocol due to medical reasons (OR 3.81, CI 1.53-9.49) and less likely due to the reason parental decision (OR 0.35, CI 0.13-0.96). Therefore, patterns of reasons for not completing vaccinations vary, depending on population. Interventions to reduce the number of children not fully vaccinated should be tailored to the specific population.

Factors associated with non- and under-vaccination among children aged 12-23 months in Malawi. A multinomial analysis of the population-based sample.

BACKGROUND: Non- and under-vaccination among children in Malawi have received little attention. Between 2010 and 2016, the proportion of children who received full immunization before their first birthday dropped from 81% to 76% in Malawi. This signifies that a certain fraction of children are either non-vaccinated or under-vaccinated. Thus, the present study attempted to examine the predictors of non- and under-vaccination among children aged 12-23 months in Malawi. METHODS: Cross-sectional data obtained from the Malawi Demographic and Health Survey 2015-16 were utilized. The percentage of children aged 12-23 months who were non-vaccinated, under-vaccinated, or fully vaccinated with 1 dose of Bacillus Calmette-Guérin, 3 doses of oral polio vaccine, 3 doses of pentavalent, 2 doses of rotavirus vaccine, 3 doses of pneumococcal vaccine and 1 dose of measles-containing vaccine were calculated. The odds of being non-vaccinated and under-vaccinated compared to full vaccination relative to various sociodemographic factors were assessed using a multivariable multinomial logistic regression with logit link function which accounted for survey design. RESULTS: Of 3111 children aged 12-23 months, 72% were fully vaccinated, 26% were under-vaccinated, and about 2% were non-vaccinated. The multinomial logistic regression showed that children from the poorest households, and children who did not have postnatal care within two months had increased odds of being under-vaccinated. On the other hand, children who had no health card or whose card was lost had increased odds of being both non- and under-vaccinated. Additionally, children from the northern region and who resided in households with either none or one under-five child had reduced odds of being non-vaccinated and under-vaccinated, respectively. CONCLUSIONS: Women from the poorest households and those who are not attending PNC should be targeted when designing interventions that aim at improving childhood vaccination in order to reduce the barriers they face in accessing vaccination services.

Reasons for non-vaccination and incomplete vaccinations among children in Pakistan.

BACKGROUND: Global immunization efforts have received a boost through the introduction of several new vaccines. These efforts however, are threatened by sub-optimal vaccine coverage, particularly in countries with large birth cohorts. Pakistan has one of the largest birth cohorts in the world, where coverage of routine vaccination remains persistently inadequate. We undertook this study to ascertain reasons for non-vaccination or incomplete vaccination of children less than two years in 8 districts of southern Pakistan. METHODS: A cross-sectional survey using WHO recommended rapid coverage assessment technique was conducted in 2014. Using probability proportional to size method, we sampled 8400 households with eligible children (aged 4-12 months). Using a structured questionnaire, mothers or other primary caregivers were interviewed to determine vaccination status of an index child. In case of non-vaccination or incomplete vaccination, respondents were asked for reasons leading to low/no vaccine uptake. RESULTS: Based on both vaccination record and recall, only 30.8% of children were fully vaccinated, 46% had an incomplete vaccination status while 23%were non-vaccinated. The most frequently reported reasons for non-vaccination included: mothers/caregivers being unaware of the need for vaccination (35.3%), a fear of side effects (23%), mother/caregiver being too busy (16.6%), distance from vaccination centers (13.8%), and non-availability of either vaccinators or vaccines at vaccination centers (10.7%). Reasons identified for incomplete vaccination were similar, with caregivers being unaware of the need for subsequent doses (27.3%), non-availability of vaccinators or vaccines (17.7%), mother/caregiver being too busy (14.8%), fear of side effects (11.2%), and postponement for another time (8.7%). CONCLUSION: Various factors result in non-compliance with vaccination schedules and vaccine refusal within the surveyed communities, ranging from lack of knowledge to non-availability of supplies at vaccination centers. These barriers are best addressed through multi-pronged strategies addressing supply gaps, increasing community awareness and enhancing demand for routine vaccination services.

Factors associated with routine childhood vaccine uptake and reasons for non-vaccination in India: 1998-2008.

BACKGROUND: Despite almost three decades of the Universal Immunization Program in India, a little more than half the children aged 12-23months receive the full schedule of routine vaccinations. We examined socio-demographic factors associated with partial-vaccination and non-vaccination and the reasons for non-vaccination among Indian children during 1998 and 2008. METHODS: Data from three consecutive, nationally-representative, District Level Household and Facility Surveys (1998-99, 2002-04 and 2007-08) were pooled. Multinomial logistic regression was used to identify individual and household level socio-demographic variables associated with the child's vaccination status. The mother's reported reasons for non-vaccination were analyzed qualitatively, adapting from a previously published framework. RESULTS: The pooled dataset contained information on 178,473 children 12-23months of age; 53%, 32% and 15% were fully vaccinated, partially vaccinated and unvaccinated respectively. Compared with the 1998-1999 survey, children in the 2007-2008 survey were less likely to be unvaccinated (Adjusted Prevalence Odds Ratio (aPOR): 0.92, 95%CI=0.86-0.98) but more likely to be partially vaccinated (aPOR: 1.58, 95%CI=1.52-1.65). Vaccination status was inversely associated with female gender, Muslim religion, lower caste, urban residence and maternal characteristics such as lower educational attainment, non-institutional delivery, fewer antenatal care visits and non-receipt of maternal tetanus vaccination. The mother's reported reasons for non-vaccination indicated gaps in awareness, acceptance and affordability (financial and non-financial costs) related to routine vaccinations. CONCLUSIONS: Persisting socio-demographic disparities related to partial-vaccination and non-vaccination were associated with important childhood, maternal and household characteristics. Further research investigating the causal pathways through which maternal and social characteristics influence decision-making for childhood vaccinations is needed to improve uptake of routine vaccination in India. Also, efforts to increase uptake should address parental fears related to vaccination to improve trust in government health services as part of ongoing social mobilization and communication strategies.

Prevalence and correlates of never vaccinated Nigerian children, aged 1-5 years.

INTRODUCTION: A unique population of Nigerian children, aged 1-5 years, never receive any of the recommended childhood vaccines. However, the characteristics of this population has not been previously described. Given Nigeria's historically poor childhood immunization coverage and high child mortality rates, it was imperative we investigate the prevalence and correlates of never-vacccination among Nigerian children. METHODS: We conducted secondary analysis of the 2013 Nigeria Demographic Health Survey data of Nigerian children, aged 12-59 months (n = 20,586). Weighted multivariate logistic regressions were used to examine the relationship between socio-demographic factors and never-vaccination of Nigerian children. Further regression analysis was conducted after stratifying by Northern and Southern regions. RESULTS: About twenty one percent of study sample, had never been vaccinated. Over eighty percent of the never-vaccinated children in our study resided in the Northern geopolitical zones of Nigeria. Child never-vaccination was found to be significantly associated with key socio-demographic characteristics. Children born into poor households, with mothers who are unemployed and uneducation, were more likely to be never-vaccinated. Unique predictors of child never-vaccination specific to Northern Nigeria were identified. Islam (aOR: 1.56, 95% CI: 1.11-2.17) and lack of access to Television or Radio (aOR: 1.49, 95% CI: 1.22-1.81) promoted never-vaccination, while increasing maternal age and rural residence (aOR: 0.63, 95% CI: 0.42-0.95) were associated with lower odds of never-vaccination. CONCLUSION: Socio-demographic factors are predictors of child never-vaccination in Nigeria. Further investigations are needed to better understand the underlying contexts that conribute to child never-vaccination in populations identified in this study. More so, it is important to examine the mechanism through which predictors that are region-speific, culminate in child never-vaccination.

Eliminar o sarampo: uma meta a alcançar / Eliminating measles: a goal to achieve

Nos últimos três anos assistimos a um aumento global do número de casos sarampo, com a ocorrência de surtos graves e prolongados em vários países do mundo. Sendo o sarampo um problema de saúde pública, a sua prevenção é fundamental para o controlo e eliminação da doença. Realizámos uma revisão Scoping, com o objetivo de mapear a literatura existente sobre os condicionalismos que levam os adultos à não adesão à vacina do sarampo. A questão de partida foi: "O que leva os adultos a não se vacinarem contra o sarampo?" O Projeto de Intervenção Comunitária decorreu numa USF de Lisboa, com a finalidade de contribuir para a prevenção do sarampo nos adultos. Para a sua consecução foi seguida a Metodologia do Planeamento em Saúde e como referencial teórico de enfermagem, o Modelo de Promoção da Saúde (MPS) de Nola Pender. Para o diagnóstico de situação, aplicámos presencialmente o questionário baseado no MPS, a 41 utentes. O tratamento dos dados foi feito através de uma análise estatística descritiva, utilizando o programa Microsoft Excel. Após a priorização dos problemas identificados, foram formulados os diagnósticos de enfermagem: "falta de conhecimentos sobre a doença", "não adesão ao regime de imunização" e "comportamentos de procura de saúde comprometido", definidos os objetivos e implementadas as estratégias de educação para a saúde com vista à capacitação dos adultos para a prevenção do sarampo. Realizámos a avaliação da intervenção e verificámos que os indicadores selecionados foram alcançados ou parcialmente alcançados e os objetivos específicos foram atingidos.

In the last three years, we have seen a global increase in the number of measles cases, with the occurrence of serious and prolonged outbreaks in several countries around the world. As measles is a public health problem, its prevention is essential for the control and elimination of the disease. We conducted a Scoping Review, with the objective of mapping the existing literature on the constraints that lead adults to non-adherence to the measles vaccine. The starting question was: "What causes adults to not get the measles vaccine?" The Community Intervention Project took place at a FHU (Family Heath Unit) in Lisbon, with the purpose of contributing to the prevention of measles in adults. To achieve this, the Health Planning Methodology was followed. The Nola Pender Health Promotion Model (HPM) was used as a theoretical framework for nursing. For the situational diagnosis, we applied the MPS based questionnaire to 41 users in person. The data was processed using descriptive statistical analysis in Microsoft Excel. After prioritizing the identified problems, the following nursing diagnoses were formulated: "lack of knowledge about the disease", "non-adherence to the immunization regime" and "compromised health-seeking behaviors". Health education strategies were then implemented, with the objective of empowering adults to prevent measles. Evaluation of the intervention was carried out. We found that the selected indicators were fully or partially achieved. Furthermore, we found that the specific objectives were fully achieved.
