Prevalence of pain and fear as barriers to vaccination in children - Systematic review and meta-analysis

Transdermal delivery of PeptiCRAd cancer vaccine using microneedle patches

Microneedles (MNs) are a prospective system in cancer immunotherapy to overcome barriers regarding proper antigen delivery and presentation. This study aims at identifying the potential of MNs for the delivery of Peptide-coated Conditionally Replicating Adenoviruses (PeptiCRAd), whereby peptides enhance the immunogenic properties of adenoviruses presenting tumor associated antigens. The combination of PeptiCRAd with MNs containing polyvinylpyrrolidone and sucrose was tested for the preservation of structure, induction of immune response, and tumor eradication. The findings indicated that MN-delivered PeptiCRAd was effective in peptide presentation in vivo, leading to complete tumor rejection when mice were pre-vaccinated. A rise in the cDC1 population in the lymph nodes of the MN treated mice led to an increase in the effector memory T cells in the body. Thus, the results of this study demonstrate that the combination of MN technology with PeptiCRAd may provide a safer, more tolerable, and efficient approach to cancer immunotherapy, potentially translatable to other therapeutic applications.

Pain and development: interacting phenomena

ABSTRACT

For decades, clinicians and researchers have observed bidirectional relationships between child development and the pain experience in childhood. Pain in childhood is an inherently developmental phenomenon, embedded in an iterative, time-dependent process that reflects individual biological, behavioral, social, psychological, and environmental characteristics that unfold across the early life span. Childhood pain can have wide ranging effects on brain development in ways that contribute-for better and worse-to social, emotional, and cognitive well-being in childhood and on into adulthood. Atypical trajectories of development in the context of disorders such as autism, cerebral palsy, ADHD, and mood/anxiety disorders also contribute to unique childhood pain experiences. In this paper, pain will be considered as a determinant of development, and conversely development will be considered as a key determinant of a child's pain experience. We will discuss how intersectional identities (eg, gender, race, socioeconomic status) and associated social, structural, systemic, and physical environments influence the relationship between development and pain. Finally, we will identify what might be needed to think "developmentally" in ways that extend from the "bench side" in the lab to the "curb side" in the community, integrating a developmental perspective into research and clinical practice to achieve health accessibility and equity in pain care for all children across the developmental spectrum.

The effect of breastfeeding on reducing pain induced by pentavalent vaccine in infants: a randomized clinical trial

OBJECTIVE

To analyze the effect of breastfeeding on reducing Pentavalent vaccination pain in infants and to identify the necessary breastfeeding interval for antinociceptive action.

METHOD

Open parallel randomized clinical trial. Ninety mother-infant dyads participated, distributed into intervention group 1 (n = 30), which breastfed five minutes before vaccination; intervention group 2 (n = 30), which breastfed five minutes before and during vaccination; and control group (n = 30), which did not breastfeed. The outcome variable was the pain level measured by the FLACC Scale. Data analysis was conducted using descriptive and inferential statistics, applying Fisher's Exact, Kolmogorov-Smirnov, Kruskal-Wallis and Dunn's multiple comparison tests, with 0.05 significance level.

RESULTS

Pain induced by the Pentavalent vaccine was reduced in intervention groups 1 and 2 (mean pain of 6.06 versus 3.83, respectively) compared to the control group (mean of pain of 7.43), which was significant for intervention group 2 (p < 0.001), indicating that, to achieve lower levels of pain, breastfeeding should be carried out before and during vaccination.

CONCLUSION

Longer breastfeeding, conducted five minutes before and during vaccination, reduces the pain induced by the Pentavalent vaccine. No vaccination risks were identified to outweigh the benefits. These results endorse that health professionals should encourage breastfeeding at least five minutes before and during vaccine injection for an antinociception effect.

Comparison of Sucrose vs. Swaddling in Pain Management during Birth Dose of Hepatitis B Vaccine: A Randomized Control Trial

OBJECTIVES

To evaluate the efficacy of pain management of 1 ml of 24% sucrose given orally compared to routine care given one minute before vaccination for reduction of pain.

METHODS

This double-blind randomized controlled trial included term neonates visiting Pediatric OPD for immunization. Neonates were randomly assigned into two groups (Group A- Sucrose, Group B- Swaddling). Commercially available sucrose solution (StayHappi solution 24%) was given in a dose of 1 ml to the neonates. Video recording of the neonate's facial expression was done during the procedure. Duration of cry, latency of onset of cry as well Modified Neonatal Facial Coding Score (MFCS) were the outcome variables.

RESULTS

The mean (SD) of birth weight and gestational age was 2729 (321.6) g and 38.24 (0.84) d, respectively. Analysis showed significant difference in total MFCS across the groups (P <0.001). Total MFCS was significantly lower in sucrose group [4.88 (1.07) vs. 7.17 (0.95)]. The duration of cry (in seconds) was also found to be significantly lower in sucrose group.

CONCLUSIONS

Administration of 1 ml 24% sucrose one minute prior to immunization is efficacious in pain management during injectable immunization.

"I Thought It Was Better to Be Safe Than Sorry": Factors Influencing Parental Decisions on HPV and Other Adolescent Vaccinations for Students with Intellectual Disability and/or Autism in New South Wales, Australia

The uptake of human papilloma virus (HPV) and other adolescent vaccinations in special schools for young people with disability is significantly lower than in mainstream settings. This study explored the factors believed to influence parental decision making regarding vaccine uptake for students with intellectual disability and/or on the autism spectrum attending special schools in New South Wales, Australia, from the perspective of all stakeholders involved in the program. Focus groups and interviews were conducted with 40 participants, including parents, school staff, and immunisation providers. The thematic analysis identified two themes: (1) appreciating diverse parental attitudes towards vaccination and (2) educating parents and managing vaccination questions and concerns. While most parents were described as pro-vaccination, others were anti-vaccination or vaccination-hesitant, articulating a marked protectiveness regarding their child's health. Reasons for vaccine hesitancy included beliefs that vaccines cause autism, concerns that the vaccination may be traumatic for the child, vaccination fatigue following COVID-19, and assumptions that children with disability will not be sexually active. Special school staff regarded the vaccination information pack as inadequate for families, and nurses described limited educational impact resulting from minimal direct communication with parents. More effective communication strategies are needed to address vaccine hesitancy among parents with children with disability.

Parental vaccine hesitancy and influenza vaccine type preferences during and after the COVID-19 Pandemic

BACKGROUND

Seasonal influenza vaccine (SIV) greatly reduces disease burden among school-aged children, yet parental vaccine hesitancy remains a persistent challenge. Two types of SIV are available for children in Hong Kong and other locations: inactivated influenza vaccine (IIV), administered through intramuscular injection, and live attenuated influenza vaccine (LAIV), administered via nasal spray. We aimed to understand how vaccine hesitancy shaped parental preference for LAIV versus IIV, particularly amidst important public health events, such as the COVID-19 pandemic and the massive rollout of COVID-19 vaccination campaigns.

METHODS

We employed a concurrent mixed-methods design. The quantitative part involves longitudinal surveys spanning three years, from pre-pandemic to post-pandemic periods, tracking parental vaccine hesitancy and preference for SIV types. The qualitative part involves 48 in-depth interviews, providing insights into parental preference for SIV types, underlying reasons, and related values.

RESULTS

Our quantitative analyses show an overall increase in parental vaccine hesitancy and preference for LAIV over IIV after the onset of the COVID-19 pandemic and especially after the rollout of the COVID-19 vaccination campaign. Further logistic regression modelling based on the cohort data shows that higher vaccine hesitancy, coupled with the COVID-19 vaccination campaign rollout, predicts a greater preference for LAIV over IIV. The qualitative analysis complements these results, highlighting that LAIV's non-invasive nature aligns with parental values of prioritizing natural immunity and concerns about overmedication, leading to a more acceptable attitude towards LAIV.

CONCLUSIONS

Leveraging the higher acceptability of LAIV compared to IIV among parents with high vaccine hesitancy could promote childhood vaccination uptake.

Early childhood risk factors for later onset of pediatric chronic pain: a multi-method longitudinal study

BACKGROUND

Pediatric chronic pain (i.e., pain lasting ≥ 3 months) is prevalent, disabling, and costly. It spikes in adolescence, interrupts psychosocial development and functioning, and often co-occurs with mental health problems. Chronic pain often begins spontaneously without prior injuries and/or other disorders. Prospective longitudinal cohort studies following children from early childhood, prior to chronic pain onset, are needed to examine contributing factors, such as early pain experiences and mental health. Using data from a longitudinal community pregnancy cohort (All Our Families; AOF), the present study examined the associations between early developmental risk factors, including early childhood pain experiences and mental health symptoms, and the onset of pediatric chronic pain at ages 8 and 11 years.

METHODS

Available longitudinal AOF data from child age 4 months, as well as 1, 2, 3, 5, 8, and 11 years, were used. Mothers reported their child's pain experiences (e.g., hospitalizations, vaccinations, gut problems) at each timepoint from 4 months to 8 years, child chronic pain at age 8, and child mental health symptoms at ages 5 and 8 years. Children reported their chronic pain frequency and interference at age 11. Adaptive least absolute shrinkage and selection operator (LASSO) regressions were used to select predictor variables. Complete case analyses were complemented by multiple imputation using chained equation (MICE) models.

RESULTS

Gut problems, emergency room visits, frequent pain complaints, and headaches at age 5 or earlier, as well as female sex, were associated with increased risk of maternal reported child chronic pain at age 8. Maternal reported chronic pain at age 8 was associated with higher levels of child-reported pain frequency and pain interferences at age 11. Boys self-reported lower levels of pain interference at age 11.

CONCLUSIONS

Some, but not all, painful experiences (e.g., gut problems, ER visits, pain complaints) in early life contribute to pediatric chronic pain onset and should be considered for screening and early intervention.

Association Between Pneumococcal Vaccination Uptake and Loneliness Among Regular Patients in Rural Community Hospitals: A Cross-Sectional Study

Introduction Vaccination is essential for preventing infectious diseases such as pneumonia and seasonal viral infections. The COVID-19 pandemic has underscored the critical role of vaccination in public health. However, vaccination uptake can be influenced by biopsychosocial conditions. Immunocompromised individuals, for instance, face restrictions with live vaccines, and psychosocial factors like loneliness can negatively impact attitudes towards vaccination. This study aims to clarify the association between loneliness and pneumococcal vaccination rate among regular patients in a rural Japanese community. Method A cross-sectional study was conducted at Unnan City Hospital in Unnan City, a rural area in southeastern Shimane Prefecture, Japan. Participants included patients over 40 who regularly visited the general medicine department between September 1, 2023, and November 31, 2023. Data on vaccination rates for pneumococcal pneumonia and loneliness levels assessed using the Japanese version of the three-item University of California, Los Angeles (UCLA) Loneliness Scale were collected. Additional data on demographics, BMI, renal function, and comorbidities were extracted from electronic medical records. Statistical analyses were performed to identify factors associated with vaccination rates, including univariate and multivariate logistic regression. Results Out of 1,024 eligible patients, 647 participated in the study. Participants with higher loneliness had significantly lower vaccination rates for pneumococcal pneumonia (22.3% vs. 34.2%, p = 0.001). The multivariate logistic regression model showed that higher loneliness was significantly associated with lower vaccination likelihood (odds ratio (OR) = 0.54, 95% CI = 0.37-0.78, p = 0.0011). Age was positively associated with vaccination (OR = 1.08, 95% CI = 1.06-1.11, p < 0.001), whereas higher comorbidity scores (Charlson Comorbidity Index (CCI) ≥ 5) and frequent healthy eating practices were associated with lower vaccination rates. Conclusion This study demonstrates a significant association between higher loneliness levels and lower pneumococcal vaccination rates among patients in a rural Japanese community. Addressing psychosocial barriers such as loneliness could enhance vaccination uptake. Public health interventions focused on reducing loneliness and enhancing social support are essential to improving vaccination rates and preventing infectious diseases. Further research should explore the causal mechanisms and develop targeted strategies to mitigate the impact of loneliness on health behaviors.

The effect of virtual reality versus standard-of-care treatment on pain perception during paediatric vaccination: A randomised controlled trial

AIMS AND OBJECTIVES

To determine the effect of immersive virtual reality (VR) on perceived pain and fear in children during vaccination and parental satisfaction with the procedure.

BACKGROUND

Virtual reality can reduce the perception of pain by children but only three studies have analysed its use during vaccination to date; these had small sample sizes and imperfect methodological designs.

DESIGN

A randomised controlled clinical trial.

METHODS

One hundred and sixty participants from the Tres Forques Health Center were randomly assigned to the intervention group (IG) (n = 82) in which distraction with immersive VR was used during the vaccination, while standard distraction techniques were used for the control group (n = 80). The primary outcome was pain (Wong-Baker FACES). Secondary outcomes included (Children's Fear Scale) and parental satisfaction with the vaccination procedure. Chi-squared tests were used for qualitative variables, relationships between quantitative variables were tested with Spearman correlations, and Mann-Whitney U- or Student t-tests were employed to assess the relationship between quantitative and qualitative variables.

RESULTS

Compared to the controls, the children in the IG reported significantly less pain and fear, while parental satisfaction was significantly higher. Reported pain and fear did not differ according to the sex of the patient. Child age was not linked to fear but was related to pain: the younger the patient, the greater the pain they described.

CONCLUSIONS

Immersive VR effectively controlled pain and fear in children during vaccination and increased parent satisfaction with the vaccination process. Patient sex did not influence the level of pain and fear but age did.

RELEVANCE TO CLINICAL PRACTICE

Improving vaccination experiences can reduce perceived pain and fear in children and increase parent satisfaction, thereby enhancing vaccination schedule adherence and improving group immunity.

REPORTING METHOD

The CONSORT Statement for non-pharmacological randomised clinical trials were followed.

Prevalence, factors associated and management of needle phobia among the general population in Saudi Arabia and Egypt

OBJECTIVE

This study aims to assess the prevalence of needle phobia among Saudi and Egyptian adult populations. In addition, underlying causes and strategies that can be utilized to address needle fear were investigated.

METHODS

A cross-sectional online survey study was conducted in Saudi Arabia and Egypt between 1 May and 30 June 2023. Participants aged 18 years and above and living in Saudi Arabia and Egypt were eligible to complete the survey. Participants were invited to participate in this study through social media platforms (Facebook, X, Snapchat, and Instagram). A convenience sampling technique was used to recruit the study participants. A 21-item questionnaire consisting of four sections including a Likert scale score was used to answer the research objectives. Numeric data were presented as mean ± SD. For categorical variables, percentages were used. Comparison between groups were made by Student's t-test or Mann Whitney test according to data distribution. Chi squared tests for categorical values were conducted. A binary logistic regression analysis was conducted to investigate factors associated with needle phobia.

RESULTS

A total of 4065 participants were involved in this study (Saudi Arabia: 2628 and Egypt: 1437). Around one-third of the study participants (36.5%) confirmed that they have needle phobia. Most of the study participants (81.1%) reported that they have had needle phobia since they were under 18 years of age. Pain, general anxiety, and fear of making a mistake during the procedure were the most commonly reported contributors for fear of needles during or before a medical procedure. Around 15.8% of the study participants reported that they have tried to get rid of phobia from needles. Non-surgical alternatives (such as oral medications and patches) and using smaller/thinner needles were the most commonly reported interventions that reduced fear of needles. Binary logistic regression analysis identified that females, those who are aged (41-50 years), widowed, those with bachelor's degrees and higher education, and those unemployed were more likely to have needle phobia compared to others.

CONCLUSION

Our study highlighted the high prevalence of needle fear within an adult population in Egypt and Saudi Arabia. Females, those who are aged (41-50 years), those widowed, those with higher education degrees, those unemployed, those working in the health sector and people with low income were more likely to have needle phobia compared to others.

The association between parent mental health and pediatric chronic pain: a systematic review and meta-analysis

ABSTRACT

Mental health problems are common among parents of children with chronic pain and associated with worse outcomes for the child with chronic pain. However, the effect sizes of these associations between parent mental health and pediatric chronic pain vary widely across studies. The aim of this systematic review and meta-analysis was to generate pooled estimates of the (1) prevalence of mental health problems among parents of children with chronic pain and (2) associations between parent mental health and the (2a) presence of child chronic pain and (2b) functioning of children with chronic pain. Embase, MEDLINE, PsycINFO, Web of Science, and CINAHL were searched up to November 2022. Observational studies that examined symptoms or diagnoses of parent anxiety, depression, or general distress and the presence of child chronic pain and/or related functioning were included. From 32,848 records, 2 coders identified 49 studies to include in random-effects meta-analyses. The results revealed that mental health problems among parents of children with chronic pain were common (anxiety: 28.8% [95% CI 20.3-39.1]; depression: 20.0% [15.7-25.2]; general distress: 32.4% [22.7-44.0]). Poorer parent mental health was significantly associated with the presence of chronic pain (anxiety: OR = 1.91 [1.51-2.41]; depression: OR = 1.90 [1.51-2.38]; general distress: OR = 1.74 [1.47-2.05]) and worse related functioning (ie, pain intensity, physical functioning, anxiety and depression symptoms; r s = 0.10-0.25, all P s < 0.05) in children. Moderator analyses were generally nonsignificant or could not be conducted because of insufficient data. Findings support the importance of addressing parent mental health in the prevention and treatment of pediatric chronic pain.

If we know better, why don't we do better? A rapid quality improvement project to increase utilization of comfort measures to reduce pain and distress in children in a COVID-19 mass vaccination clinic

INTRODUCTION

Many evidence-based tools exist to address pain and distress associated with injections; however, there remains a large gap between the knowledge of these tools and their utilization. Our hospital began a quality improvement (QI) project prior to COVID-19, with the goal of increasing the utilization of Comfort Promise measures during needle procedures. When COVID-19 vaccinations were approved, our mass vaccination clinics provided an opportunity to rapidly increase utilization across the institution. The primary aim was to increase the percentage of comfort measures (CM) offered with COVID-19 vaccinations.

METHODS

Through this QI project, nurses and other professionals implemented CMs during COVID mass vaccination clinics. Clinics occurred in 3 age-based waves. Waves served as Plan-Do-Study-Act (PDSA) cycles. Families completed post-vaccination surveys to determine what CMs were offered and intention for future use with vaccinations.

RESULTS

Uptake of CMs (PainEase, ShotBlockers, Comfort Positioning, Alternative Focus, Topical Lidocaine, and Breastfeeding/Sucrose) throughout the waves increased and generally remained stable. CMs also seemed to decrease pain/distress with vaccinations (70.5 to 88.7%), and children/caregivers intended to use some combination for future vaccinations (82.5 to 98.5%).

CONCLUSIONS

Fast-paced mass vaccination clinics provided an ideal opportunity to significantly increase utilization of CMs. Across age groups CMs yielded high satisfaction and interest in future utilization. Clinic nurses returned to their own sub-specialties and became change agents.

IMPLICATIONS

If all healthcare providers can work together to achieve consensus while incorporating comfort measures into daily practice, sustained change with incorporation of these evidence-based tools can be achieved. Future directions are discussed.

SimSAARlabim study - The role magic tricks play in reducing pain and stress in children

BACKGROUND

Vaccination is an essential preventative medical intervention, but needle fearandinjection painmay result in vaccination hesistancy.

STUDY PURPOSE

To assess the role of magic tricks - no trick vs. one trick ("disappearing handkerchief trick") vs. three tricks ("disappearing handkerchief trick", "jumping rubber band trick", and "disappearing ring trick") - performed by a professional magician and pediatrician during routine vaccination in reducing discomfort/pain and the stress response (heart rate, visual analogue scale (VAS), and biomarkers (cortisol, Immunoglobulin A (IgA), α-amylase, and overall protein concentration in saliva before and after vaccination).

PATIENTS AND METHODS

Randomized controlled trial (RCT) in healthy children aged 6-11 years undergoing routine vaccination in an outpatient setting.

RESULTS

50 children (26 female) were enrolled (no trick: n = 17, 1 trick: n = 16, 3 tricks: n = 17) with a median age of 6.9 years (range: 5.3-10.8 years). We detected no significant differences among the three groups in their stress reponse (heart rate before and after vaccination and cortisol, IgA, α-amylase, and overall protein concentrations in saliva before and after vaccination) or regarding pain assessment using the VAS.

CONCLUSIONS

Although children undergoing routine outpatient vaccination appeared to enjoy a magician's presence, the concomitant performance of magic tricks revealed no significant effect on the stress response.

Strategies for Improving Vaccine Communication and Uptake

Vaccines have led to a significant decrease in rates of vaccine-preventable diseases and have made a significant impact on the health of children. However, some parents express concerns about vaccine safety and the necessity of vaccines. The concerns of parents range from hesitancy about some immunizations to refusal of all vaccines. This clinical report provides information about the scope and impact of the problem, the facts surrounding common vaccination concerns, and the latest evidence regarding effective communication techniques for the vaccine conversation. After reading this clinical report, readers can expect to: Understand concepts and underlying determinants of vaccine uptake and vaccine hesitancy.Understand the relationship between vaccine hesitancy and costs of preventable medical care.Recognize and address specific concerns (eg, vaccine safety) with caregivers when hesitancy is present.

CARD (Comfort Ask Relax Distract) for school-based immunizations in Calgary, Canada: a pragmatic cluster trial

ABSTRACT

School-based immunizations are fear-inducing events for many students and contribute to vaccine hesitancy. We developed an immunization delivery framework called the CARD (Comfort Ask Relax Distract) system that incorporates evidence-based interventions to improve the experience (eg, reduce fear, pain, dizziness). We evaluated CARD in grades 6 and 9 students in Calgary, Canada. In this pragmatic, hybrid, effectiveness-implementation, cluster trial, we randomized 8 Community Health Centres providing regional immunization services to CARD or control (usual care). In the CARD group, public health staff educated students about CARD and planned processes to reduce fear cues and support student coping choices during immunization. Students self-reported fear, pain, and dizziness during immunization using a 0-10 numerical rating scale; staff recorded procedure details, including vaccines administered, fainting episodes, and coping strategies used. Staff participated in focus groups afterward. Altogether, 8839 children from 105 schools in the 2019 to 2020 school calendar year were included. Fear was lower for CARD (mean = 3.6 [SD = 3.1] vs control 4.1 [3.2]; mean difference = -0.5; 95% confidence interval = -0.74 to -0.21; P < 0.001). Effectiveness persisted after stratification by student gender (male and female) and grade level (grade 6 and grade 9). Other symptoms did not differ. Compared with control, CARD students used peers, privacy, muscle tension, and topical anesthetics more; verbal distraction, deep breathing, and adult support were used less frequently ( P < 0.05, all analyses). Immunization rate did not differ. Staff reported positive to neutral attitudes about CARD. In summary, this pragmatic trial demonstrated that CARD improved the immunization experiences of students at school.

A review of potential use cases for measles-rubella, measles-mumps-rubella, and typhoid-conjugate vaccines presented on microarray patches

As an innovative vaccine delivery technology, vaccine microarray patches could have a meaningful impact on routine immunization coverage in low- and middle-income countries, and vaccine deployment during epidemics and pandemics. This review of the potential use cases for a subset of vaccine microarray patches in various stages of clinical development, including measles-rubella, measles-mumps-rubella, and typhoid conjugate, highlights the breadth of their applicability to support immunization service delivery and their potential scope of utilization within national immunization programs. Definition and assessment of the use cases for this novel vaccine presentation provide important insights for vaccine developers and policymakers into the strengths of the public health and commercial value propositions, and the preparatory requirements for public health systems for the future rollout of vaccine microarray patches. An in-depth understanding of use cases for vaccine microarray patches serves as a foundational input to overcoming the remaining technical, regulatory, and financial challenges. Additional efforts will help to realize the potential of vaccine microarray patches as part of the global effort to improve the coverage and equity of national immunization programs.

A scalable synthesis of adjuvanting antigen depots based on metal-organic frameworks

Vaccines have saved countless lives by preventing and even irradicating infectious diseases. Commonly used subunit vaccines comprising one or multiple recombinant proteins isolated from a pathogen demonstrate a better safety profile than live or attenuated vaccines. However, the immunogenicity of these vaccines is weak, and therefore, subunit vaccines require a series of doses to achieve sufficient immunity against the pathogen. Here, we show that the biomimetic mineralization of the inert model antigen, ovalbumin (OVA), in zeolitic imidazolate framework-8 (ZIF-8) significantly improves the humoral immune response over three bolus doses of OVA (OVA 3×). Encapsulation of OVA in ZIF-8 (OVA@ZIF) demonstrated higher serum antibody titers against OVA than OVA 3×. OVA@ZIF vaccinated mice displayed higher populations of germinal center (GC) B cells and IgG1+ GC B cells as opposed to OVA 3×, indicative of class-switching recombination. We show that the mechanism of this phenomenon is at least partly owed to the metalloimmunological effects of the zinc metal as well as the sustained release of OVA from the ZIF-8 composite. The system acts as an antigen reservoir for antigen-presenting cells to traffic into the draining lymph node, enhancing the humoral response. Lastly, our model system OVA@ZIF is produced quickly at the gram scale in a laboratory setting, sufficient for up to 20 000 vaccine doses.

Creating a Low-Stimulus Clinic to improve immunization success rates for children with alternate environment needs: A quality improvement initiative

Patients with specific sensory needs may face barriers to receiving their immunizations. Therefore, a Low-Stimulus Clinic was created in Alberta. Modifications to regular clinic space included lower visual and auditory input, access to longer appointment times and private clinic spaces, development of pre-appointment comfort plans, and offering of in-vehicle immunization. Between April 2021 and May 2022, 90% (641/712) of booked patients were successfully immunized. The top reasons for accessing the clinic included autism spectrum disorder (229/712, 32%), and needle fear/phobia (195/712, 27%). The Low-Stimulus Clinic had a high rate of successful vaccination for populations that may otherwise have been less likely to receive immunizations. Its workflows support the principles of choice, collaboration, and control in creating a positive immunization experience for patients and their families. Having such clinics widely available is a key step in reducing barriers to accessing vaccines for individuals with specific sensory needs.

Ethical Challenges of Advances in Vaccine Delivery Technologies

Strategies to address misinformation and hesitancy about vaccines, including the fear of needles, and to overcome obstacles to access, such as the refrigeration that some vaccines demand, strongly suggest the need to develop new vaccine delivery technologies. But, given widespread distrust surrounding vaccination, these new technologies must be introduced to the public with the utmost transparency, care, and community involvement. Two emerging technologies, one a skin-patch vaccine and the other a companion dye and detector, provide excellent examples of greatly improved delivery technologies for which such a careful approach should be developed in order to increase vaccine uptake. Defusing fears and conspiracy mongering must be a key part of their rollout.

Pain management in infant immunisation: A cross-sectional survey of UK primary care nurses

BACKGROUND

Childhood immunisation is a critically important public health initiative. However, since most vaccines are administered by injection, it is associated with considerable pain and distress. Despite evidence demonstrating the efficacy of various pain management strategies, the frequency with which these are used during routine infant vaccinations in UK practice is unknown.

AIM

This study aimed to explore primary care practice nurses' (PNs) use of evidence-based pain management strategies during infant immunisation, as well as barriers to evidence-based practice.

METHODS

A questionnaire was developed and distributed to nurses throughout the UK via convenience sampling in paper and online formats. Questions assessed the frequency of pain management intervention use during infant immunisation and barriers to their use.

FINDINGS

A total of 255 questionnaire responses were received. Over 90% (n = 226) of respondents never used topical anaesthetics or sweet solutions during immunisations, while 41.9% advised breastfeeding occasionally (n = 103). Parent-/caregiver-led distraction was the most frequently used intervention, with most nurses using it occasionally (47.9%, n = 116) or often (30.6%, n = 74). Most practices had no immunisation pain management policy (81.1%, n = 184), and most PNs' previous training had not included pain management (86.9%, n = 186). Barriers to intervention use included lack of time, knowledge and resources. Excluding distraction, pain management strategies were infrequently or never used during infant immunisation. Key barriers to using evidence-based strategies were lack of time, knowledge and resources.

Mobile Vaccination Teams for Improving Vaccination Coverage in the Kyrgyz Republic: Results of a National Health System-Strengthening Project during the First Two Years of the COVID-19 Pandemic

(1) Background: This implementation study reports on the results of the mobile vaccination teams' (MVTs) activities during the first two years of the COVID-19 pandemic in Kyrgyzstan, when other vaccination services were disrupted. (2) Methods: Through a national health system-strengthening project under an order of the Ministry of Health, in 2020, the number of MVTs was increased, focusing on internal immigrant settlements around the cities of Bishkek and Osh and geographically remote areas. MVTs provided free vaccination services. (3) Results: MVTs vaccinated a total of 125,289 and 158,047 children in 2020 and 2021, respectively. The higher contribution of MVTs to vaccination coverage was in children under 5 years of age, with the three top vaccines being IPV (8.9%), MMR (7%), and PCV (6.6%). In 2021, 13,000 children who had not received an IPV vaccination and 8692 children who had not received the Pentavalent vaccine (DPT-HBV-Hib) were reached. The number of cases of vaccine-preventable disease reported in official statistics has reduced over time. (4) Conclusions: MVTs increased vaccination coverage in Kyrgyzstan, in particular in remote regions and migrant settlements, where it accounted for a considerable proportion of the vaccinated. This study adds to previous evidence in the literature of the role of MVTs as a strategy to improve immunization in hard-to-reach populations, particularly children.

Changes in Students' Perceptions Regarding Adolescent Vaccinations through a Before-After Study Conducted during the COVID-19 Pandemic: GIRASOLE Project Study

The COVID-19 pandemic caused a reduction in vaccination coverage for all age groups, especially in non-infant age. The main objective of the present study is to evaluate the effectiveness of an online intervention conducted among adolescents during the COVID-19 pandemic in increasing knowledge and positive attitudes toward vaccinations. The study, which took place online from March to May 2021, involved 267 students from six lower secondary schools in Palermo city (Italy); they filled out the questionnaire before and after the intervention. The questionnaire was based on the protection motivation theory (PMT), which estimates the improvement in vaccination-related knowledge and attitudes. The pre- and post-intervention comparison showed a significant increase in the perception of the disease severity: strongly agree pre-intervention n = 150 (58.6%) and post-intervention n = 173 (67.6%, p < 0.001), rated on a five-point Likert scale. In a multivariate analysis, the factor associated with the improvement in the score after the intervention was the school dropout index (low vs. very high dropout index OR 4.5; p < 0.03). The educational intervention was more effective in schools with lower early school leaving rates, an indirect index of socio-economic status. The topic of vaccination has caught the adolescents' attention, it is, therefore, important that interventions tackling teenagers are tailored to reduce their emotional tension about the perception of adverse effects and improve vaccination coverage.

Liposome-based vaccines for minimally or noninvasive administration: an update on current advancements

INTRODUCTION

Vaccination requires innovation to provide effective protection. Traditional vaccines have several drawbacks, which can be overcome with advanced technologies and different administration routes. Over the past 10  years, a significant amount of research has focussed on the delivery of antigens into liposomes due to their dual role as antigen-carrying systems and vaccine adjuvants able to increase the immunogenicity of the carried antigen.

AREAS COVERED

This review encompasses the progress made over the last 10  years with liposome-based vaccines designed for minimally or noninvasive administration, filling the gaps in previous reviews and providing insights on composition, administration routes, results achieved, and Technology Readiness Level of the most recent formulations.

EXPERT OPINION

Liposome-based vaccines administered through minimally or noninvasive routes are expected to improve efficacy and complacency of vaccination programs. However, the translation from lab-scale production to large-scale production and collaborations with hospitals, research centers, and companies are needed to allow new products to enter the market and improve the vaccination programs in the future.

Picturing Bravery: A Rapid Review of Needle Procedures Depicted in Children's Picture Books

Existing research has identified evidence-based strategies for mitigating fear and pain during needle procedures; yet, families often experience limited access to health professionals who deliver these interventions. Children may benefit from learning about such strategies in a developmentally appropriate and accessible format such as a picture book. This review aimed to summarize content related to needle procedures represented in picture books for 5- to 8-year-old children. Key terms were searched on Amazon, and the website was used to screen for relevant eligibility criteria. Three levels of screening and exclusions resulted in a final sample of 48 books. Quantitative content analysis was used to apply a coding scheme developed based on relevant Clinical Practice Guidelines and systematic reviews. Cohen's Kappa indicated strong reliability, and frequencies were calculated to summarize the content. The books were published between 1981 and 2022. All 48 books included at least one evidence-based coping strategy. Distressing aspects such as scary visuals were often included (27.1%), as well as specific expressions of fear (52.1%) and pain (16.7%). Overall, this study paves the way for researchers interested in evaluating the effectiveness of picture books on children's knowledge and self-efficacy, as well as creating interventions for coping.

How to use participatory design to develop an eHealth intervention to reduce preprocedural stress and anxiety among children visiting the hospital: The Hospital Hero app multi-study and pilot report

BACKGROUND

Medical procedures can cause considerable stress and anxiety among children. Current interventions mainly diminish stress and anxiety during procedures, while stress and anxiety often build up at home. Moreover, interventions often focus on either distraction or preparation. eHealth can combine multiple strategies and provide a low-cost solution that can be used outside the hospital.

OBJECTIVE

To develop an eHealth solution to diminish preprocedural stress and anxiety, and to evaluate the app on use, usability and user experience in practice. We also aimed to gain in-depth insights in children's and caregivers' opinions and experiences to inform future improvements.

METHODS

This is a multi-study report on the development (Study 1) and evaluation (Study 2) of a first version of the developed app. In study 1 we adopted a participatory design approach in which children's experiences were central to the design process. We performed an experience journey session with stakeholders (n = 13) to map the child's outpatient journey, identify pains and gains, and formulate the desired experience journey. Iterative development and testing with children (n = 8) and caregivers (n = 6) resulted in a working prototype. The prototype was tested with children, resulting in a first version of the Hospital Hero app. The app was evaluated on use, user-experience and usability during an eight-week pilot study in practice (Study 2). We triangulated data from online interviews with children and caregivers (n = 21) and online questionnaires (n = 46).

RESULTS

Multiple stress and anxiety experience touchpoints were identified. The Hospital Hero app supports children in their hospital journey by facilitating preparation at home and providing distraction at the hospital. The pilot study showed that the app was evaluated positively on usability and user-experience and is considered feasible. Qualitative data showed five themes: (1) user-friendliness, (2) coherence and power of storytelling, (3) motivation and reward, (4) fit with real hospital journey, (5) procedural comfort.

DISCUSSION

Using participatory design, we developed a child-centered solution that supports children in the entire hospital journey and may diminish preprocedural stress and anxiety. Future efforts should create a more tailored journey, define an optimal engagement window and formulate implementation strategies.
