CARD (Comfort Ask Relax Distract) for community pharmacy vaccinations in children: Effect on immunization stress-related responses and satisfaction.

Introduction: CARD (Comfort Ask Relax Distract) is a vaccine delivery program demonstrated to reduce pain, fear and associated immunization stress-related responses (ISRR) in children undergoing vaccinations at school. This study evaluated CARD's clinical impact when integrated into community pharmacy-based pediatric vaccinations. Methods: This was a before-and-after CARD implementation study in 5 independent pharmacies offering COVID-19 vaccinations to children aged 5-11 years. No changes were made to practices in the "before" phase. CARD interventions were integrated in the "after" phase (e.g., children prepared a coping plan using a checklist, distraction toolkits were placed in waiting and vaccination spaces, vaccinations were performed with privacy, needles were obscured). Children self-reported ISRR, including fear, pain and dizziness during vaccination, and both children and parents/caregivers (herein, parents) compared the child's experience to their last needle (better, same, worse). In the "after" phase, parents and children reported how much CARD helped (not at all, a little bit, a moderate amount, a lot). Results: The study was conducted between January 16 and March 20, 2022. Altogether, 152 children participated (71 before and 81 after CARD); demographic characteristics did not differ. Children's self-reported fear was lower after CARD, when assessed continuously (2.5 vs 3.7 out of 10; p = 0.02) or dichotomously, using a cut-off of 0 vs >0 (58% vs 80%; p = 0.01). Pain was lower when assessed dichotomously (<2 vs ≥2; p = 0.03). There was no difference in dizziness. After CARD, children and parents reported more positive experiences compared to the child's last needle (p = 0.01, both analyses) and more children and parents reported that distraction and child participation in the process were helpful (p < 0.001, both analyses). Overall, 92% of children and 91% of parents said CARD helped. Conclusion: CARD reduced children's fear and improved vaccination experiences for children and parents when integrated in community pharmacy-based vaccinations.

Integration of CARD (Comfort Ask Relax Distract) for COVID-19 community pharmacy vaccination in children: Effect on implementation outcomes.

Introduction: Community pharmacists report that providing vaccinations can be challenging, particularly if the vaccine recipient is a child, because of heightened levels of fear. The objective of this study was to determine acceptability and feasibility of the CARD (Comfort Ask Relax Distract) system as a vaccination delivery framework for children receiving COVID-19 vaccinations in a community pharmacy setting. CARD incorporates evidence-based interventions that reduce fear and immunization stress-related responses in vaccine recipients and was demonstrated to be effective and feasible in other vaccination settings providing vaccinations to children and adults. Methods: This mixed-methods study involved 5 independent pharmacies (with 6 vaccinators) offering COVID-19 vaccinations to children between 5 and 11 years of age. Vaccinating staff and implementation leads from the pharmacy organization participated in a small-scale CARD implementation project (before-and-after design). Afterwards, they filled in quantitative surveys and provided qualitative feedback about their perceptions and experiences in focus group discussions. Qualitative data were analyzed deductively, using the Consolidated Framework for Implementation Research (CFIR). Results: The study was conducted between January 16 and March 20, 2022. Across both quantitative and qualitative measures, vaccinating staff reported positive attitudes about CARD and alignment with their professional roles. They reported that CARD reduced children's fear and improved the vaccination experiences in children and parents and for themselves. Vaccinators reported increased confidence due to CARD. They reported compatibility of CARD interventions within their practice and that it was time neutral. They maintained use of some interventions after the study. They also provided suggestions and shared concerns about fidelity and future feasibility of continuing various components of the program. Conclusion: CARD was demonstrated to be acceptable and feasible by vaccinators performing vaccinations in children in community pharmacies.

Improved maternal-fetal outcomes among emergency obstetric referrals following phone call communication at a teaching hospital in south western Uganda: a quasi-experimental study.

BACKGROUND: Emergency obstetric referrals develop adverse maternal-fetal outcomes partly due to delays in offering appropriate care at referral hospitals especially in resource limited settings. Referral hospitals do not get prior communication of incoming referrals leading to inadequate preparedness and delays of care. Phone based innovations may bridge such communication challenges. We investigated effect of a phone call communication prior to referral of mothers in labour as intervention to reduce preparation delays and improve maternal-fetal outcome at a referral hospital in a resource limited setting. METHODS: This was a quasi-experimental study with non-equivalent control group conducted at Mbarara Regional Referral Hospital (MRRH) in South Western Uganda from September 2020 to March 2021. Adverse maternal-fetal outcomes included: early neonatal death, fresh still birth, obstructed labour, ruptured uterus, maternal sepsis, low Apgar score, admission to neonatal ICU and hysterectomy. Exposure variable for intervention group was a phone call prior maternal referral from a lower health facility. We compared distribution of clinical characteristics and adverse maternal-fetal outcomes between intervention and control groups using Chi square or Fisher's exact test. We performed logistic regression to assess association between independent variables and adverse maternal-fetal outcomes. RESULTS: We enrolled 177 participants: 75 in intervention group and 102 in control group. Participants had similar demographic characteristics. Three quarters (75.0%) of participants in control group delayed on admission waiting bench of MRRH compared to (40.0%) in intervention group [p = < 0.001]. There were significantly more adverse maternal-fetal outcomes in control group than intervention group (obstructed labour [p = 0.026], low Apgar score [p = 0.013] and admission to neonatal high dependency unit [p = < 0.001]). The phone call intervention was protective against adverse maternal-fetal outcome [aOR = 0.22; 95%CI: 0.09-0.44, p = 0.001]. CONCLUSION: The phone call intervention resulted in reduced delay to patient admission at a tertiary referral hospital in a resource limited setting, and is protective against adverse maternal-fetal outcomes. Incorporating the phone call communication intervention in the routine practice of emergency obstetric referrals from lower health facilities to regional referral hospitals may reduce both maternal and fetal morbidities.

Transition to endemic: acceptance of additional COVID-19 vaccine doses among Canadian adults in a national cross-sectional survey.

BACKGROUND: Additional doses of COVID-19 vaccine have been proposed as solutions to waning immunity and decreased effectiveness of primary doses against infection with new SARS-CoV-2 variants. However, the effectiveness of additional vaccine doses relies on widespread population acceptance. We aimed to assess the acceptance of additional COVID-19 vaccine doses (third and annual doses) among Canadian adults and determine associated factors. METHODS: We conducted a national, cross-sectional online survey among Canadian adults from October 14 to November 12, 2021. Weighted multinomial logistic regression analyses were used to identify sociodemographic and health-related factors associated with third and annual dose acceptance and indecision, compared to refusal. We also assessed influences on vaccine decision-making, and preferences for future vaccine delivery. RESULTS: Of 6010 respondents, 70% reported they would accept a third dose, while 15.2% were undecided. For annual doses, 64% reported acceptance, while 17.5% were undecided. Factors associated with third dose acceptance and indecision were similar to those associated with annual dose acceptance and indecision. Previous COVID-19 vaccine receipt, no history of COVID-19 disease, intention to receive an influenza vaccine, and increasing age were strongly associated with both acceptance and indecision. Chronic illness was associated with higher odds of acceptance, while self-reported disability was associated with higher odds of being undecided. Higher education attainment and higher income were associated with higher odds of accepting additional doses. Minority first language was associated with being undecided about additional doses, while visible minority identity was associated with being undecided about a third dose and refusing an annual dose. All respondents reported government recommendations were an important influence on their decision-making and identified pharmacy-based delivery and drop-in appointments as desirable. Co-administration of COVID-19 and influenza vaccines was viewed positively by 75.5% of the dose 3 acceptance group, 12.3% of the undecided group, and 8.4% of the refusal group. CONCLUSIONS: To increase acceptance, targeted interventions among visible minority and minority language populations, and those with a disability, are required. Offering vaccination at pharmacies and through drop-in appointments are important to facilitate uptake, while offering COVID-19/influenza vaccine co-administration may have little benefit among those undecided about additional doses.

Vaccine Hesitancy, Acceptance, and Anti-Vaccination: Trends and Future Prospects for Public Health.

An often-stated public health comment is that "vaccination is a victim of its own success." While the scientific and medical consensus on the benefits of vaccination is clear and unambiguous, an increasing number of people are perceiving vaccines as unsafe and unnecessary. The World Health Organization identified "the reluctance or refusal to vaccinate despite availability of vaccines" as one of the 10 threats to global health in 2019. The negative influence of anti-vaccination movements is often named as a cause of increasing vaccine resistance in the public. In this review, we give an overview of the current literature on the topic, beginning by agreeing on terminology and concepts before looking at potential causes, consequences, and impacts of resistance to vaccination.

Feasibility of implementation of CARD™ for school-based immunizations in Calgary, Alberta: a cluster trial.

BACKGROUND: Negative experiences with school-based immunizations can contribute to vaccine hesitancy in youth and adulthood. We developed an evidence-based, multifaceted and customizable intervention to improve the immunization experience at school called the CARD™ (C-Comfort, A-Ask, R-Relax, D-Distract) system. We evaluated the feasibility of CARD™ implementation for school-based immunizations in Calgary, Canada. METHODS: In a mixed methods study, two Community Health Centres providing immunization services, including 5 schools each with grade 9 students (aged approximately 14 years), were randomized to CARD™ or control (usual care). In the CARD™ group, public health staff and students were educated about coping strategies prior to immunization clinics. Clinics were organized to reduce fear and to support student's choices for coping strategies. Public health staff in the CARD™ group participated in a focus group discussion afterwards. We sought a recruitment rate of 80% for eligible schools, an external stakeholder focus group (e.g., school staff) with 6 or more individuals, 85% of individual injection-related data acquisition (student and immunizer surveys), and 80% absolute agreement between raters for a subset of data that were double-coded. Across focus groups, we examined perceptions of acceptability, appropriateness, feasibility and fidelity of CARD™. RESULTS: Nine (90%) of eligible schools participated. Of 219 students immunized, injection-related student and immunizer data forms were acquired for 195 (89.0%) and 196 (89.5%), respectively. Reliability of data collection was high. Fifteen public health and 5 school staff participated in separate focus groups. Overall, attitudes towards CARD™ were positive and compliance with individual components of CARD™ was high. Public health staff expressed skepticism regarding the value of student participation in the CARD™ system. Suggestions were made regarding processes to refine implementation. CONCLUSION: While most outcome criteria were satisfied and overall perceptions of implementation outcomes were positive, some important challenges and opportunities were identified. Feedback is being used to inform a large cluster trial that will evaluate the impact of CARD™ during school-based immunizations. TRIAL REGISTRATION: The trial is registered at ClinicalTrials.gov ( NCT03948633 ); Submitted April 24, 2019.

Factors associated with parents' experiences using a knowledge translation tool for vaccination pain management: a qualitative study.

BACKGROUND: Vaccination is a common painful procedure for children. Parents' concern regarding vaccination pain is a significant driver of vaccine hesitancy. Despite the wealth of evidence-based practices available for managing vaccination pain, parents lack knowledge of, and access to, these strategies. Knowledge translation (KT) tools can communicate evidence-based information to parents, however little is known about what factors influence parents' use of these tools. A two-page, electronic KT tool on psychological, physical, and pharmacological vaccination pain management strategies for children, was shared with parents as part of a larger mixed methods study, using explanatory sequential design, exploring factors related to uptake of this KT tool. The aim of this qualitative study was to understand what influenced parents' perceptions of the relevance of the KT tool, as well as their decision as to whether to use the tool. METHODS: A qualitative descriptive design was used. A total of 20 parents of children aged 0-17 years (n = 19 mothers) reviewed the KT tool ahead of their child's upcoming vaccination and participated in a semi-structured interview at follow-up. Interviews were recorded, transcribed verbatim, and analyzed with reflexive thematic analysis using an inductive approach. RESULTS: The analysis generated three interrelated themes which described factors related to parents' use of the KT tool: (1) Relevance to parents' needs and circumstances surrounding their child's vaccination; (2) Alignment with parents' personal values around, and experiences with, vaccination pain management (e.g., the importance of managing pain); and (3) Support from the clinical environment for implementing evidence-based strategies (e.g., physical clinical environment and quality of interactions with the health care provider). CONCLUSIONS: Several factors were identified as central to parents' use of the KT tool, including the information itself and the clinical environment. When the tool was perceived as relevant, aligned with parents' values, and was supported by health care providers, parents were more inclined to use the KT tool to manage their children's vaccination pain. Future research could explore other factors related to promoting engagement and uptake when creating parent-directed KT tools for a range of health-related contexts.

Association of Maternal Influenza Vaccination During Pregnancy With Early Childhood Health Outcomes.

Importance: Seasonal influenza vaccination in pregnancy can reduce influenza illness among pregnant women and newborns. Evidence is limited on whether seasonal influenza vaccination in pregnancy is associated with adverse childhood health outcomes. Objective: To assess the association between maternal influenza vaccination during pregnancy and early childhood health outcomes. Design, Setting, and Participants: Retrospective cohort study, using a birth registry linked with health administrative data. All live births in Nova Scotia, Canada, between October 1, 2010, and March 31, 2014, were included, with follow-up until March 31, 2016. Adjusted hazard ratios (HRs) and incidence rate ratios (IRRs) with 95% confidence intervals were estimated while controlling for maternal medical history and other potential confounders using inverse probability of treatment weighting. Exposures: Seasonal influenza vaccination during pregnancy. Main Outcomes and Measures: Childhood outcomes studied were immune-related (eg, asthma, infections), non-immune-related (eg, neoplasms, sensory impairment), and nonspecific (eg, urgent or inpatient health care utilization), measured from emergency department and hospitalization databases. Results: Among 28 255 children (49% female, 92% born at ≥37 weeks' gestation), 10 227 (36.2%) were born to women who received seasonal influenza vaccination during pregnancy. During a mean follow-up of 3.6 years, there was no significant association between maternal influenza vaccination and childhood asthma (incidence rate, 3.0 vs 2.5 per 1000 person-years; difference, 0.53 per 1000 person-years [95% CI, -0.15 to 1.21]; adjusted HR, 1.22 [95% CI, 0.94 to 1.59]), neoplasms (0.32 vs 0.26 per 1000 person-years; difference, 0.06 per 1000 person-years [95% CI, -0.16 to 0.28]; adjusted HR, 1.26 [95% CI, 0.57 to 2.78]), or sensory impairment (0.80 vs 0.97 per 1000 person-years; difference, -0.17 per 1000 person-years [95% CI, -0.54 to 0.21]; adjusted HR, 0.82 [95% CI, 0.49 to 1.37]). Maternal influenza vaccination in pregnancy was not significantly associated with infections in early childhood (incidence rate, 184.6 vs 179.1 per 1000 person-years; difference, 5.44 per 1000 person-years [95% CI, 0.01 to 10.9]; adjusted IRR, 1.07 [95% CI, 0.99 to 1.15]) or with urgent and inpatient health services utilization (511.7 vs 477.8 per 1000 person-years; difference, 33.9 per 1000 person-years [95% CI, 24.9 to 42.9]; adjusted IRR, 1.05 [95% CI, 0.99 to 1.16]). Conclusions and Relevance: In this population-based cohort study with mean follow-up duration of 3.6 years, maternal influenza vaccination during pregnancy was not significantly associated with an increased risk of adverse early childhood health outcomes.

Is physician dismissal of vaccine refusers an acceptable practice in Canada? A 2018 overview.

Despite robust evidence that routine immunization is effective and safe, some parents refuse some or all vaccines for their children. In 2007, concern that Canadian paediatricians and family physicians might be considering dismissal of vaccine refusers from their practices prompted an ethical, legal, and public health analysis which concluded that dismissal was professionally problematic. We now reassess this important issue in the Canadian context updating ethical, legal, and public health considerations highlighting changes since 2007. In light of the recent strengthening of Ontario's school immunization requirements that include stiffer steps to qualify for a medical, conscience, or religious belief exemption, physicians and health care workers may be under more pressure from vaccine refusers in their practice leading some to contemplate dismissal or even consider no longer offering immunizations at all in their practice. Given the challenges that vaccine refusers may present, we offer an overview for managing vaccine refusal by parents/patients in a medical practice.

Effectiveness of a hospital-based postnatal parent education intervention about pain management during infant vaccination: a randomized controlled trial.

BACKGROUND: Parents have reported that they want to learn how to reduce pain in infants during vaccinations. Our objective was to compare different levels of intensity of postnatal education about pain mitigation on parental self-reported use of interventions at future infant vaccinations. METHODS: We conducted a longitudinal, 3-group parallel, add-on, randomized controlled trial on the postnatal ward of a hospital. New mothers, unaware of the hypothesis, were randomly assigned to 1 of 3 intervention groups and 3 follow-up groups (i.e., 9 groups, 3 × 3). The 3 intervention groups were control (general immunization information), pain pamphlet (pain mitigation information), and pain pamphlet and pain video (pain mitigation information). Both pain mitigation education groups also received general immunization information. The 3 follow-up groups were 2-, 4- and 6-month infant vaccinations. Mothers reported use of breastfeeding, sucrose and topical anesthetics during infant vaccinations in a telephone survey. RESULTS: Of 3420 participants, follow-up was available for 2549 (75%): 36.1%, 34.2% and 29.7% reported on pain mitigation practices at 2-, 4- and 6-month vaccinations, respectively (p = 0.9). Maternal characteristics did not differ (p > 0.05): mean age, 33.6 years; 58% were primipara. Utilization of any intervention (breastfeeding, sucrose or topical anesthetics) was 53.2%, 61.4% and 63.0% for control, pain pamphlet, and pain pamphlet and pain video groups, respectively (p < 0.001); both pain education groups had higher utilization than the control group, but did not differ from one another. Uptake differed among intervention groups at 2 and 4 months but not at 6 months. INTERPRETATION: Hospital-based postnatal education increased parental use of pain interventions at infant vaccinations and can be added to existing education. TRIAL REGISTRATION: ClinicalTrials.gov, no. NCT01937143.

Addressing vaccine hesitancy in immunization programs, clinics and practices.

This practice point offers evidence-based guidance for provincial/territorial immunization programs, clinics and office practices on how to address hesitancy and improve vaccine uptake rates. Steps to take include the following: 1) Detecting under-immunized subgroups (which requires record-keeping), diagnosis, and targeted interventions; 2) Educating all health care workers involved with immunization on best practices; 3) Employing evidence-based strategies to increase uptake, including reminders, convenient clinic hours and locations, and tailored communication; 4) Educating children, youth, and adults on the importance of immunization for health; and 5) Working collaboratively across provincial/territorial jurisdictions and with the federal government, nongovernmental organizations, community leaders and health services.

Working with vaccine-hesitant parents: An update.

Most Canadian parents make sure that their children are immunized on time, but health care providers often encounter parents who are hesitant about vaccination or refuse recommended vaccines. This practice point offers evidence-based guidance to clinicians on how to work with vaccine-hesitant parents. Steps include: 1) Understanding the health care provider's key role in parental decision-making and not dismissing vaccine refusers from practice; 2) Using presumptive and motivational interviewing techniques to identify specific vaccine concerns; 3) Using effective, clear language to present evidence for disease risks and vaccine benefits fairly and accurately; 4) Managing pain on immunization; and 5) Reinforcing the importance of and parental responsibility for community protection. Immunization is one of the most important preventive health measures in existence and responsible for saving millions of lives. Addressing the concerns of vaccine-hesitant parents is a priority for health care providers.

Head lice infestations: A clinical update.

Head lice (Pediculus humanus capitis) infestations are not a primary health hazard or a vector for disease, but they are a societal problem with substantial costs. Diagnosis of head lice infestation requires the detection of a living louse. Although pyrethrins and permethrin remain first-line treatments in Canada, isopropyl myristate/ST-cyclomethicone solution and dimeticone can be considered as second-line therapies when there is evidence of treatment failure.

Knowledge, attitude and behaviour towards the use of insecticide treated mosquito nets among pregnant women and children in rural Southwestern Uganda.

BACKGROUND: The burden of malaria in Uganda remains unacceptably high, especially among children and pregnant women. To prevent malaria related complications, household possession and use of Insecticide Treated mosquito Nets (ITNs) has become a common practice in the country. Despite the availability of ITNs, malaria remains a foremost public health concern in Uganda. We sought to explore knowledge, attitude, and behaviour towards the use of ITNs as a nightly malaria prevention strategy among pregnant women and children under five years of age in Isingiro district, Southwestern Uganda. MATERIALS AND METHODS: This was a community based, descriptive cross-sectional study, in which households with children under 5 years, and/or pregnant women were enrolled. We used a structured questionnaire to collect data on participants' understanding of the causes, signs and symptoms of malaria; use of ITNs to prevent malaria; attitudes and behaviours towards the use of ITNs. We also conducted key informant interviews (KIIs) to get in-depth understanding of responses from the participants. We analysed quantitative data using STATA version 12.Qualitative findings from the KIIs were transcribed and translated, and manually analysed using thematic content analysis. RESULTS: Of the 369 households enrolled, 98.4% (N = 363) households had children under five. Most participants (41.2%, N = 152) were in the 21-30 age category (mean age; 32.2 years). 98.1% (N = 362) of the respondents considered ITNs a key malaria prevention strategy. The ITN possession rate was 84.0% (N = 310), of these, 66.1% (N = 205) consistently used them. 39% of the respondents did not have a positive attitude towards ITNs. CONCLUSIONS: Although 84.0% of the respondents possessed ITNs, many were not consistently using them. To this, there is need to engage all stakeholders (including cultural leaders, community health workers, religious leaders and the government) in the malaria prevention campaigns using ITNs through: a) government's concerted effort to ensure universal access of right fit ITNs, b) end-user directed health education to emphasize positive attributes of ITN use, c) telling the ITN success stories to improve on the usage.

Canada's eight-component vaccine safety system: A primer for health care workers.

Concerns about vaccine safety make some parents hesitant about immunization. Health care providers are pivotal in helping parents understand that Canada is a leader in vaccine safety. The present practice point provides an update on the eight components of Canada's vaccine safety system: (1) an evidence-based pre-license review and approval process; (2) strong regulations for manufacturers; (3) independent evidence-based vaccine use recommendations; (4) immunization competency training and standards for health care providers; (5) pharmacovigilance programs to detect and (6) determine causality of adverse events following immunization (AEFIs); (7) a program for vaccine safety and efficacy signal detection; and (8) the Canadian Immunization Research Network's special immunization clinics for children who have experienced serious AEFIs.

Taking the sting out of school-based immunizations.

Pain and fear widely contribute to negative experiences for students during school-based immunizations. In this preliminary research, we used a pre-existing network of 50 schools across Canada that participated in a biannual national immunization poster competition for grade 6 students organized by Immunize Canada to survey principals, teachers and students about their experiences with immunization pain and fear, how they want to learn about managing pain and fear and opportunities to include this information in the process of immunization. Responses revealed that both pain and fear are relevant to the immunization experience and that education and interventions are welcome by students and school staff. This may lead to improved attitudes about immunization, as well as future compliance with recommended immunizations.

La douleur et la peur contribuent largement aux expériences négatives des élèves lors de la vaccination scolaire. Dans le cadre de la présente recherche préliminaire, les auteurs ont recouru à un réseau déjà formé de 50 écoles du Canada qui avaient participé à un concours national bisannuel d'affiches sur la vaccination organisé par Immunisation Canada auprès d'élèves de sixième année. Ils ont sondé les directions d'école, les enseignants et les élèves au sujet de leurs expériences de douleur et de peur liées à la vaccination, de ce qu'ils veulent savoir sur la gestion de la douleur et de la peur ainsi que des possibilités d'intégrer l'information au processus de vaccination. Les réponses ont révélé que la douleur et la peur s'associent à l'expérience de vaccination et que les élèves et le personnel scolaire seraient heureux de recevoir de l'information et des interventions. Ces mesures pourraient améliorer les attitudes vis-à-vis de la vaccination et favoriser l'adhérence aux futurs vaccins.

Maternal Influenza Immunization and Adverse Birth Outcomes: Using Data and Practice to Inform Theory and Research Design.

Maternal influenza immunization can reduce influenza-attributable morbidity and mortality among pregnant women and infants who are too young to be vaccinated. Data from empirical studies also support the hypothesis that immunization can protect the fetus against adverse outcomes if the mother is exposed to influenza. In their theoretical analysis in the Journal, Hutcheon et al. (Am J Epidemiol 2016;184(3):227-232) critiqued the existing evidence of the fetal benefits of maternal influenza immunization by calculating the sample sizes needed to demonstrate hypothetical reductions in risk and concluded that the benefits observed in empirical studies are likely implausible. However, in their analysis, they did not take into account multiple fundamental characteristics of influenza epidemiology, including the time-variable effects of influenza illness and vaccination during pregnancy, or well-known differences in disease epidemiology between seasons, populations, and geographic regions. Although these and other factors might affect the magnitude of fetal benefit conferred by maternal influenza immunization, studies in which investigators have accounted for influenza circulation have demonstrated a consistent protective effect against a variety of adverse birth outcomes; those studies include the only randomized controlled trial designed a priori and adequately powered to do so. Only a comprehensive and nuanced assessment of the evidence base will allow for effective translation of these data into a global immunization policy.
