RESUMO

Importance: Although child mortality trends have decreased worldwide, deaths among children younger than 5 years of age remain high and disproportionately circumscribed to sub-Saharan Africa and Southern Asia. Tailored and innovative approaches are needed to increase access, coverage, and quality of child health care services to reduce mortality, but an understanding of health system deficiencies that may have the greatest impact on mortality among children younger than 5 years is lacking. Objective: To investigate which health care and public health improvements could have prevented the most stillbirths and deaths in children younger than 5 years using data from the Child Health and Mortality Prevention Surveillance (CHAMPS) network. Design, Setting, and Participants: This cross-sectional study used longitudinal, population-based, and mortality surveillance data collected by CHAMPS to understand preventable causes of death. Overall, 3390 eligible deaths across all 7 CHAMPS sites (Bangladesh, Ethiopia, Kenya, Mali, Mozambique, Sierra Leone, and South Africa) between December 9, 2016, and December 31, 2021 (1190 stillbirths, 1340 neonatal deaths, 860 infant and child deaths), were included. Deaths were investigated using minimally invasive tissue sampling (MITS), a postmortem approach using biopsy needles for sampling key organs and fluids. Main Outcomes and Measures: For each death, an expert multidisciplinary panel reviewed case data to determine the plausible pathway and causes of death. If the death was deemed preventable, the panel identified which of 10 predetermined health system gaps could have prevented the death. The health system improvements that could have prevented the most deaths were evaluated for each age group: stillbirths, neonatal deaths (aged <28 days), and infant and child deaths (aged 1 month to <5 years). Results: Of 3390 deaths, 1505 (44.4%) were female and 1880 (55.5%) were male; sex was not recorded for 5 deaths. Of all deaths, 3045 (89.8%) occurred in a healthcare facility and 344 (11.9%) in the community. Overall, 2607 (76.9%) were deemed potentially preventable: 883 of 1190 stillbirths (74.2%), 1010 of 1340 neonatal deaths (75.4%), and 714 of 860 infant and child deaths (83.0%). Recommended measures to prevent deaths were improvements in antenatal and obstetric care (recommended for 588 of 1190 stillbirths [49.4%], 496 of 1340 neonatal deaths [37.0%]), clinical management and quality of care (stillbirths, 280 [23.5%]; neonates, 498 [37.2%]; infants and children, 393 of 860 [45.7%]), health-seeking behavior (infants and children, 237 [27.6%]), and health education (infants and children, 262 [30.5%]). Conclusions and Relevance: In this cross-sectional study, interventions prioritizing antenatal, intrapartum, and postnatal care could have prevented the most deaths among children younger than 5 years because 75% of deaths among children younger than 5 were stillbirths and neonatal deaths. Measures to reduce mortality in this population should prioritize improving existing systems, such as better access to antenatal care, implementation of standardized clinical protocols, and public education campaigns.

RESUMO

National public health institutes (NPHIs)-science-based governmental agencies typically part of, or closely aligned with, ministries of health-have played a critical part in many countries' responses to the COVID-19 pandemic. Through listening sessions with NPHI leadership, we captured the experiences of NPHIs in Africa. Our research was further supplemented by a review of the literature. To address issues related to COVID-19, NPHIs in Africa developed a variety of innovative approaches, such as working with the private sector to procure and manage vital supplies and address key information needs. Creative uses of technology, including virtual training and messaging from drones, contributed to sharing information and battling misinformation. Positive impacts of the pandemic response include increased laboratory capacity in many countries, modernized surveillance systems, and strengthened public-private partnerships; much of this enhanced capacity is expected to persist beyond the pandemic. However, several challenges remain, including the lack of staff trained in areas like bioinformatics (essential for genomic analysis) and the need for sustained relationships and data sharing between NPHIs and agencies not traditionally considered public health (eg, those related to border crossings), as well as the impact of the pandemic on prevention and control of non-COVID-19 conditions-both infectious and noncommunicable. Participants in the listening sessions also highlighted concerns about inequities in access to, and quality of, the public health services and clinical care with resultant disproportionate impact of the pandemic on certain populations. COVID-19 responses and challenges highlight the need for continued investment to strengthen NPHIs and public health infrastructure to address longstanding deficiencies and ensure preparedness for the next public health crisis.

RESUMO

As countries face public health emergencies, building public health capacity to prevent, detect, and respond to threats is a priority. In recent years, national public health institutes (NPHIs) have emerged to play a critical role in strengthening public health systems and to accelerate and achieve implementation of the International Health Regulations (IHR 2005). NPHIs are science-based government institutions that provide national leadership and expertise for the country's efforts to protect and improve health. Providing a Legal Framework for a National Public Health Institute is a recently released Africa CDC publication intended to support NPHI development throughout Africa. Here we present a legal mapping analysis of sampled legal domains for 5 countries, using the "Menu of Considerations for an NPHI Legal Framework." The analysis delineates the types of legal authorities countries may use to establish or enhance NPHIs and demonstrates how legal mapping can be used to review legal instruments for NPHIs. It also demonstrates variability among legal approaches countries take to establish and enable public health functions for NPHIs. This article examines how the legal framework and menu of considerations can help countries understand the nuances around creating and implementing the laws that will govern their organizations and how countries can better engage stakeholders to identify or address potential areas for opportunity where law may be used as a tool to strengthen public health infrastructure.

RESUMO

BACKGROUND: In this study, we assessed impact of two educational interventions designed to increase coverage of three vaccines recommended during adolescence among Georgia middle and high school students (tetanus diphtheria pertussis [Tdap], meningococcal [MenACWY], and human papillomavirus [HPV] vaccines). METHODS: We randomized 11 middle and high schools in one school district into one of three arms: (1) control; (2) educational intervention for parents only (P only); and (3) multicomponent educational intervention for parents and adolescents (P + A), which consisted of educational brochures for parents about vaccines recommended during adolescence and a vaccine-focused curriculum delivered to adolescents by science teachers. We obtained vaccination coverage data during intervention years from the state immunization registry. RESULTS: Odds of receiving at least one vaccine during the study were higher among adolescents in P + A arm compared to control (Odds Ratio [OR]: 1.4; 95% Confidence Interval [CI]: 1.1-2.0). Adolescents in P + A arm had greater odds of receiving at least one vaccine compared with those in P only arm (OR: 1.4; 95% CI: 1.1-1.7). CONCLUSIONS: A multicomponent educational intervention for adolescents and parents increased adolescent vaccination uptake. Results suggest similar interventions can increase awareness and demand for vaccines among parents and adolescents.

RESUMO

In the past 200years, vaccines have had unmistakable impacts on public health including declines in morbidity and mortality, most markedly in economically-developed countries. Highly engineered vaccines including vaccines for conditions other than infectious diseases are expected to dominate future vaccine development. We examine immunization vaccine policy as a driver of vaccine innovation and development. The pathways to recommendation for use of licensed vaccines in the US, UK, Canada and Australia have been similar, including: expert review of disease epidemiology, disease burden and severity; vaccine immunogenicity, efficacy and safety; programmatic feasibility; public demand; and increasingly cost-effectiveness. Other attributes particularly important in development of future vaccines are likely to include: duration of immunity for improved vaccines such as pertussis; a greater emphasis on optimizing community protection rather than direct protection only; programmatic implementation, feasibility, improvements (as in the case of development of a universal influenza vaccine); public concerns/confidence/fears related to outbreak pathogens like Ebola and Zika virus; and major societal burden for combating hard to treat diseases like HIV and antimicrobial resistant pathogens. Driving innovation and production of future vaccines faces enormous economic hurdles as available approaches, technologies and regulatory pathways become more complex. As such, cost-mitigating strategies and focused, aligned efforts (by governments, private organizations, and private-public partnerships) will likely be needed to continue to spur major advances in vaccine technologies and development.

RESUMO

BACKGROUND: Vaccination coverage with tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine in pregnancy or immediately postpartum has been low. Limited data exist on rigorously evaluated interventions to increase maternal vaccination, including Tdap. Tailored messaging based on the Elaboration Likelihood Model (ELM) framework has been successful in improving uptake of some public health interventions. We evaluated the effect of two ELM-based vaccine educational interventions on Tdap vaccination among pregnant African American women, a group of women who tend to have lower vaccine uptake compared with other groups. METHODS: We conducted a prospective randomized controlled trial to pilot test two interventions - an affective messaging video and a cognitive messaging iBook - among pregnant African American women recruited during routine prenatal care visits. We measured Tdap vaccination during the perinatal period (during pregnancy and immediately postpartum), reasons for non-vaccination, and intention to receive Tdap in the next pregnancy. RESULTS: Among the enrolled women (n=106), 90% completed follow-up. Tdap vaccination in the perinatal period was 18% in the control group; 50% in the iBook group (Risk Ratio [vs. control group]: 2.83; 95% CI, 1.26-6.37), and 29% in the video group (RR: 1.65; 95% CI, 0.66-4.09). From baseline to follow-up, women's reported intention to receive Tdap during the next pregnancy improved in all three groups. Among unvaccinated women, the most common reason reported for non-vaccination was lack of a recommendation for Tdap by the woman's physician. CONCLUSIONS: Education interventions that provide targeted information for pregnant women in an interactive manner may be useful to improve Tdap vaccination during the perinatal period. However, larger studies including multiple racial and ethnic groups are needed to evaluate robustness of our findings. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01740310.

RESUMO

STUDY OBJECTIVE: The purpose of this study was to: 1) describe parental sources of information about human papillomavirus (HPV) vaccination for adolescents, 2) understand how parental sources of information about HPV vaccine are associated with adolescent HPV vaccine uptake, and 3) understand if the relationship between a greater number of HPV-related information sources and HPV vaccine uptake among adolescents is mediated by parental attitudes. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTIONS: We conducted a 3-arm randomized controlled trial in middle and high schools in eastern Georgia from 2011 to 2013. As part of the trial, we surveyed parents during the final year to understand their sources of information about HPV vaccine for their adolescent. Data were collected from 360 parents via phone and online surveys. MAIN OUTCOME MEASURES: Parents responded to a survey that asked them to identify demographic information, parental HPV attitudes, sources of information about HPV vaccination, and HPV vaccine uptake. RESULTS: Most of the sample was African American (74%; n = 267) and 53% of parents (n = 192) reported that their adolescent received at least 1 HPV vaccine dose. The top sources of information about HPV vaccine reported by parents were a doctor or medical professional (80%; n = 287) and television (64%; n = 232). A mediation analysis showed sources of information about HPV vaccine are associated with parental attitudes, and parental attitudes about HPV vaccine are associated with vaccine uptake among adolescents. CONCLUSION: These findings highlight the importance of HPV sources of information on parental attitudes.

RESUMO

OBJECTIVE: Understanding whether interventions designed to improve antenatal vaccine uptake also change women's knowledge about vaccination is critical for improving vaccine coverage. This exploratory study evaluates the effectiveness of a multi-component influenza and tetanus, diphtheria, and acellular pertussis (Tdap) vaccine promotion package on improving women's knowledge, attitudes and beliefs toward antenatal vaccination. STUDY DESIGN: In 2012/2013 a cluster-randomized trial was conducted to test the effectiveness of a vaccine promotion package on improving antenatal vaccine coverage. Participants included 325 unvaccinated pregnant women from 11 obstetric practices in Georgia. Eleven health beliefs measures were assessed at baseline and 2-3 months post-partum. Outcomes were differences in proportions of women citing favorable responses to each measure between study groups at follow-up. RESULTS: Women enrolled in their third trimester had a higher probability of asking family members to vaccinate to protect the infant if they were in the intervention group versus the control group (36% vs. 22%; risk ratio [RR] = 1.65, 95% confidence interval [CI]: 1.21, 2.26). A similar association was not observed among women enrolled before their third trimester (39% vs. 44%; RR = 0.93, 95% CI: 0.50, 1.73). There were no other significant differences at follow-up between study groups. CONCLUSIONS: While exposure to the intervention package may have raised awareness that vaccinating close contacts can protect an infant, there is little evidence that the package changed women's attitudes and beliefs toward antenatal vaccination. Future research should ensure adequate exposure to the intervention and consider study design aspects including power to assess changes in secondary outcomes, discriminatory power of response options, and social desirability bias. This study is registered with clinicaltrials.gov, study ID NCT01761799.

RESUMO

Despite high utilization of childhood vaccinations, adolescent immunization coverage rates lag behind recommended coverage levels. The four vaccines recommended for adolescents ages 11 to 18 years are tetanus, diphtheria, and pertussis vaccine; human papillomavirus vaccine; meningococcal conjugate vaccine; and an annual influenza vaccine. The Healthy People 2020 goal is 80% coverage for each recommended immunization, but coverage rates in Georgia among adolescents fall below those goals for all but the tetanus, diphtheria, and pertussis vaccine. We developed a multicomponent intervention that included a school-based, teacher-delivered educational curriculum to increase adolescent vaccination coverage rates in Richmond County, Georgia. We facilitated focus group discussions with middle- and high school science teachers who delivered the immunization curriculum in two consecutive school years. The objective of the focus group was to understand teachers' perspectives about the curriculum impact and to synthesize recommendations for optimal dissemination of the curriculum content, structure, and packaging. Teachers provided recommendations for curriculum fit within existing classes, timing of delivery, and dosage of delivery and recommended creating a flexible tool kit, such as a downloadable online package. Teachers also recommended increasing emphasis on disease transmission and symptoms to keep students engaged. These findings can be applied to the development of an online, cost-effective tool kit geared toward teaching adolescents about the immune system and adolescent vaccinations.

RESUMO

Globally, polio cases have reached an all-time low, and type 2 poliovirus (one of three) is eradicated. Oral polio vaccine (OPV) has been the primary tool, however, in rare cases, OPV induces paralysis. In 2013, the World Health Assembly endorsed the phased withdrawal of OPV and introduction of inactivated poliovirus vaccine (IPV) into childhood routine immunization schedules. Type 2 OPV will be withdrawn through a globally synchronized "switch" from trivalent OPV (all three types) to bivalent OPV (types 1 and 3). The switch will happen in 155 OPV-using countries between April 17(th) and May 1(st), 2016. Planned activities to reduce type 2 outbreak risks post-switch include the following: tOPV campaigns to increase type 2 immunity prior to the switch, monovalent OPV2 stockpiling to respond to outbreaks should they occur, containment of both wild and vaccine type 2 viruses, enhanced acute flaccid paralysis (AFP) and environmental surveillance, outbreak response protocols, and ensured access to IPV and bivalent OPV.

RESUMO

PURPOSE: Four vaccines are routinely recommended for adolescents: tetanus, diphtheria, and acellular pertussis (Tdap); human papillomavirus (HPV); meningococcal-conjugate (MCV4); and a yearly seasonal influenza vaccine. Vaccination promotion and outreach approaches may need to be tailored to certain populations, such as those with chronic health conditions or without health insurance. METHODS: In a controlled trial among middle and high school students in Georgia, 11 schools were randomized to one of three arms: no intervention, parent education brochure, or parent education brochure plus a student curriculum on the four recommended vaccines. Parents in all arms were surveyed regarding their adolescent's vaccine receipt, chronic health conditions, and health insurance status. RESULTS: Of the 686 parents, most (91%) reported their adolescent had received at least one of the four vaccines: Tdap (82%), MCV4 (59%), current influenza vaccine (53%) and HPV (48%). Twenty-three percent of parents reported that their adolescent had asthma. Most parents reported that their adolescent's insurance was Medicaid (60%) or private insurance (34%), and 6% reported no insurance. More adolescents with a chronic health condition received any adolescent vaccine than adolescents without a chronic health condition (p < .0001). Among those with no insurance, fewer had received any adolescent vaccine than those with Medicaid or private insurance (p < .0001). CONCLUSIONS: The federal Vaccines for Children program offers recommended vaccines free to eligible children (including those without health insurance). Our findings suggest that parents may not be aware of this program or eligibility for it, thus revealing a need for education or other fixes.

RESUMO

BACKGROUND: Safety data from countries with experience in the use of inactivated poliovirus vaccine (IPV) are important for the global polio eradication strategy to introduce IPV into the immunisation schedules of all countries. In the USA, IPV has been included in the routine immunisation schedule since 1997. We aimed to analyse adverse events after IPV administration reported to the US Vaccine Adverse Event Reporting System (VAERS). METHODS: We analysed all VAERS data associated with IPV submitted between Jan 1, 2000, and Dec 31, 2012, either as individual or as combination vaccines, for all age and sex groups. We analysed the number and event type (non-serious, non-fatal serious, and death reports) of individual reports, and explored the most commonly coded event terms to describe the adverse event. We classified death reports according to previously published body-system categories (respiratory, cardiovascular, neurological, gastrointestinal, other infectious, and other non-infectious) and reviewed death reports to identify the cause of death. We classified sudden infant death syndrome as a separate cause of death considering previous concerns about sudden infant syndrome after vaccines. We used empirical Bayesian data mining methods to identify disproportionate reporting of adverse events for IPV compared with other vaccines. Additional VAERS data from 1991 to 2000 were analysed to compare the safety profiles of IPV and oral poliovirus vaccine (OPV). FINDINGS: Of the 41,792 adverse event reports submitted, 39,568 (95%) were for children younger than 7 years. 38,381 of the reports for children in this age group (97%) were for simultaneous vaccination with IPV and other vaccines (most commonly pneumococcal and acellular pertussis vaccines), whereas standalone IPV vaccines accounted for 0·5% of all reports. 34,880 reports were for non-serious events (88%), 3905 reports were for non-fatal serious events (10%), and 783 reports were death reports (2%). Injection-site erythema was the most commonly coded term for non-serious events (29%), and pyrexia for non-fatal serious events (38%). Most deaths (96%) were in children aged 12 months or younger; most (52%) had sudden infant death syndrome as the reported cause of death. The safely profiles of combined IPV and whole-cell pertussis vaccines, OPV and whole-cell pertussis vaccines, and OPV and acellular pertussis vaccines were similar. We noted no indication of disproportionate reporting of adverse events after immunisation with IPV-containing vaccines compared with other vaccines between 1990 and 2013. INTERPRETATION: Fairly few adverse events were reported for the more than 250 million IPV doses distributed between 2000 and 2012. Sudden infant death syndrome reports after IPV were consistent with reporting patterns for other vaccines. No new or unexpected vaccine safety problems were identified for fatal, non-fatal serious, and non-serious reports in this assessment of adverse events after IPV. FUNDING: None.

RESUMO

In 2011-2012, only 34% of 13-17 years olds in the United States (US) received seasonal influenza vaccine. Little is known about the link between parents' sources of health information, their vaccine-related attitudes, and vaccination of their adolescent against influenza. This study seeks to determine the relationship between number of sources of information on influenza vaccine, parental attitudes toward influenza vaccine, and influenza vaccine uptake in adolescents. We conducted a telephone and web-based survey among US parents of students enrolled in 6 middle and 5 high schools in Georgia. Bivariate and multivariable analyses were conducted to examine associations between the number of information sources about influenza vaccine and vaccine receipt and whether parent vaccine-related attitudes act as a mediator. The most commonly reported sources of information were: a physician/medical professional (95.0%), a family member or friend (80.6%), and television (77.2%). Parents who had higher attitude scores toward influenza vaccine were 5 times as likely to report their adolescent had ever received influenza vaccine compared to parents who had lower attitude scores (adjusted odds ratio (aOR) 5.1; 95% confidence intervals (CI) 3.1-8.4; P < 0.01). Parent vaccine-related attitudes were a significant mediator of the relationship between sources of information and vaccine receipt. In light of the low response rate and participation in an adolescent vaccination intervention, findings may not be generalizable to other populations. This study shows the importance of multiple sources of information in influencing parental decision-making about influenza vaccine for adolescents. Harnessing the power of mass media and family members and friends as health advocates for influenza vaccination can potentially help increase vaccination coverage of adolescents.

RESUMO

Human papillomavirus (HPV) vaccination coverage for adolescent females and males remains low in the United States. We conducted a 3-arm randomized controlled trial (RCT) conducted in middle and high schools in eastern Georgia from 2011-2013 to determine the effect of 2 educational interventions used to increase adolescent vaccination coverage for the 4 recommended adolescent vaccines: Tdap, MCV4, HPV and influenza. As part of this RCT, this article focuses on: 1) describing initiation and completion of HPV vaccine series among a diverse population of male and female adolescents; 2) assessing parental attitudes toward HPV vaccine; and 3) examining correlates of HPV vaccine series initiation and completion. Parental attitude score was the strongest predictor of HPV vaccine initiation among adolescents (adjusted odds ratio (aOR): 2.08; 95% confidence interval (CI): 1.80, 2.39). Other correlates that significantly predicted HPV series initiation were gender, study year, and intervention arm. Parental attitudes remained a significant predictor of receipt of 3 doses of HPV vaccine along with gender, race, school type and insurance type. This study demonstrates that positive parental attitudes are important predictors of HPV vaccination and critical to increasing coverage rates. Our findings suggest that more research is needed to understand how parental attitudes are developed and evolve over time.

RESUMO

Live attenuated oral polio vaccine (OPV) and inactivated polio vaccine (IPV) are the tools being used to achieve eradication of wild polio virus. Because OPV can rarely cause paralysis and generate revertant polio strains, IPV will have to replace OPV after eradication of wild polio virus is certified to sustain eradication of all polioviruses. However, uncertainties remain related to IPV's ability to induce intestinal immunity in populations where fecal-oral transmission is predominant. Although substantial effectiveness and safety data exist on the use and delivery of OPV and IPV, several new research initiatives are currently underway to fill specific knowledge gaps to inform future vaccination policies that would assure polio is eradicated and eradication is maintained.

RESUMO

BACKGROUND: Improving influenza and tetanus, diphtheria and acellular pertussis (Tdap) vaccine coverage among pregnant women is needed. PURPOSE: To assess factors associated with intention to receive influenza and/or Tdap vaccinations during pregnancy with a focus on perceptions of influenza and pertussis disease severity and influenza vaccine safety. METHODS: Participants were 325 pregnant women in Georgia recruited from December 2012 - April 2013 who had not yet received a 2012/2013 influenza vaccine or a Tdap vaccine while pregnant. Women completed a survey assessing influenza vaccination history, likelihood of receiving antenatal influenza and/or Tdap vaccines, and knowledge, attitudes and beliefs about influenza, pertussis, and their associated vaccines. RESULTS: Seventy-three percent and 81% of women believed influenza and pertussis, respectively, would be serious during pregnancy while 87% and 92% believed influenza and pertussis, respectively, would be serious to their infants. Perception of pertussis severity for their infant was strongly associated with an intention to receive a Tdap vaccine before delivery (p=0.004). Despite perceptions of disease severity for themselves and their infants, only 34% and 44% intended to receive antenatal influenza and Tdap vaccines, respectively. Forty-six percent had low perceptions of safety regarding the influenza vaccine during pregnancy, and compared to women who perceived the influenza vaccine as safe, women who perceived the vaccine as unsafe were less likely to intend to receive antenatal influenza (48% vs. 20%; p < 0.001) or Tdap (53% vs. 33%; p < 0.001) vaccinations. CONCLUSIONS: Results from this baseline survey suggest that while pregnant women who remain unvaccinated against influenza within the first three months of the putative influenza season may be aware of the risks influenza and pertussis pose to themselves and their infants, many remain reluctant to receive influenza and Tdap vaccines antenatally. To improve vaccine uptake in the obstetric setting, our findings support development of evidence-based vaccine promotion interventions which emphasize vaccine safety during pregnancy and mention disease severity in infancy.

RESUMO

Four vaccines are recommended by The Advisory Committee for Immunization Practices for adolescents: tetanus, diphtheria, acellular pertussis vaccine (Tdap), meningococcal conjugate vaccine (MCV4), human papillomavirus vaccine (HPV), and annual seasonal influenza vaccine. However, coverage among adolescents is suboptimal. School-located vaccination clinics (SLVCs) offer vaccines to students at school, increasing access. This study seeks to determine the relationship between attitudes of parents of middle- and high-school students and acceptance of SLVCs for all four adolescent recommended vaccines. We conducted a telephone and web-based survey among parents of students enrolled in six middle and five high schools in Georgia. Analyses were conducted to examine associations between parental attitudes and willingness to allow their child to be vaccinated at school. Tdap and influenza vaccine had the highest rates of parental SLVC acceptance while HPV vaccine had the lowest. Parents who accepted SLVCs had higher perceived severity of influenza, meningococcal, and HPV illnesses compared to parents who did not accept SLVC. Intention to vaccinate was associated with SLVC acceptance for Tdap [Adjusted OR (AOR) 7.38; 95% confidence interval (CI) 2.44-22.31], MCV4 (AOR 2.97; 95% CI 1.67-5.28), and HPV vaccines (AOR 7.61; 95% CI 3.43-16.89). Social norms were associated with acceptance of SLVCs for influenza vaccine (AOR 1.44; 95% CI 1.12-1.84). These findings suggest parents of adolescents are generally supportive of SLVCs for recommended adolescent vaccines. Perceived severity of illness and intention to get their adolescent vaccinated were the most consistent correlates of parental SLVC acceptance for all vaccines. Future SLVC planning should focus on perceptions of disease severity and benefits of vaccination.

RESUMO

In mid-2012 we conducted survey of immunization program managers (IPMs) for the purpose of describing relationships between immunization programs and emergency preparedness programs, IPM's perceptions of challenges encountered and changes made or planned in programmatic budgeting, vaccine allocation and pandemic plans as a result of the H1N1 vaccination campaign. Over 95% of IPMs responded (61/64) to the survey. IPMs reported that a primary budget-related challenge faced during H1N1 included staff-related restrictions that limited the ability to hire extra help or pay regular staff overtime resulting in overworked regular staff. Other budget-related challenges related to operational budget shortfalls and vaccine procurement delays. IPMs described overcoming these challenges by increasing staff where possible, using executive order or other high-level support by officials to access emergency funds and make policy changes, as well as expedite hiring and spending processes according to their pandemic influenza plan or by direction from leadership. Changes planned for response to future pandemic vaccine allocation strategies were to "tailor the strategy to the event" taking into account disease virulence, vaccine production rates and public demand, having flexible vaccine allocation strategies, clarifying priority groups for vaccine receipt to providers and the public, and having targeted clinics such as through pharmacies or schools. Changes already made to pandemic plans were improving strategies for internal and external communication, improving vaccine allocation efficiency, and planning for specific scenarios. To prepare for future pandemics, programs should ensure well-defined roles, collaborating during non-emergency situations, sustaining continuity in preparedness funding, and improved technologies.
