RESUMO
OBJECTIVE: We examined Vaccine Information Statements (VIS) dissemination practices and parental use and perceptions. METHODS: We conducted a national online panel survey of 2603 US parents of children aged <7. Primary outcomes included reported VIS receipt, delivery timing, reading experiences, and perceived utility. RESULTS: Most parents received a VIS (77.2%; [95% CI: 74.5-79.7%]), 59.7% [56.6-62.7%] before vaccination but 14.5% [12.5-16.8%] reported receiving it after their child's immunization; 15.1% [13.0-17.6%] were unsure of receipt status or timing; another 10.7% [9.0-12.6%] reported non-receipt of a VIS. Less than half who received a VIS before vaccination completed it before vaccination (46.2% [42.4, 50.0%]), but most who read at least some found the information useful (95.7% [93.8-97.0%]). Parents who delayed or refused at least one recommended non-influenza vaccine reported fewer opportunities to ask providers VIS questions. CONCLUSIONS: Most parents report receiving VIS before vaccination as per federal guidelines. Continued effort is needed to enhance VIS distribution practice and parent-provider VIS content communication.

OBJECTIVE: Understanding the current status of parents' vaccine decision making is crucial to inform public policy. We sought to assess changes in vaccine decisions among parents of young children. METHODS: We conducted a web-based national poll of parents of children <7years in 2012 and 2014. Participants reported vaccine decisions for their youngest child. We calculated survey-weighted population estimates of overall immunizations decisions, and delay/refusal rates for specific vaccines. RESULTS: In 2012, 89.2% (95% CI, 87.3-90.8%) reported accepting or planning to accept all recommended non-influenza childhood vaccines, 5.5% (4.5-6.6%) reported intentionally delaying one or more, and 5.4% (4.1-6.9%) reported refusing one or more vaccines. In 2014, the acceptance, delay, and refusal rates were 90.8% (89.3-92.1%), 5.6% (4.6-6.9%), and 3.6% (2.8-4.5%), respectively. Between 2012 and 2014, intentional vaccine refusal decreased slightly among parents of older children (2-6years) but not younger children (0-1years). The proportion of parents working to catch up on all vaccines increased while those refusing some but not all vaccines decreased. The South experienced a significant increase in estimated acceptance (90.1-94.1%) and a significant decrease in intentional ongoing refusal (5.0-2.1%). Vaccine delay increased in the Northeast (3.2-8.8%). CONCLUSIONS: Nationally, acceptance and ongoing intentional delay of recommended non-influenza childhood vaccines were stable. These findings suggest that more effort is warranted to counter persistent vaccine hesitancy, particularly at the local level. Longitudinal monitoring of immunization attitudes is also warranted to evaluate temporal shifts over time and geographically.

In October 2014, the College of Medicine and Allied Health Sciences of the University of Sierra Leone, the Sierra Leone Ministry of Health and Sanitation, and CDC joined the global effort to accelerate assessment and availability of candidate Ebola vaccines and began planning for the Sierra Leone Trial to Introduce a Vaccine against Ebola (STRIVE). STRIVE was an individually randomized controlled phase II/III trial to evaluate efficacy, immunogenicity, and safety of the recombinant vesicular stomatitis virus Ebola vaccine (rVSV-ZEBOV). The study population was health care and frontline workers in select chiefdoms of the five most affected districts in Sierra Leone. Participants were randomized to receive a single intramuscular dose of rVSV-ZEBOV at enrollment or to receive a single intramuscular dose 18-24 weeks after enrollment. All participants were followed up monthly until 6 months after vaccination. Two substudies separately assessed detailed reactogenicity over 1 month and immunogenicity over 12 months. During the 5 months before the trial, STRIVE and partners built a research platform in Sierra Leone comprising participant follow-up sites, cold chain, reliable power supply, and vaccination clinics and hired and trained at least 350 national staff. Wide-ranging community outreach, informational sessions, and messaging were conducted before and during the trial to ensure full communication to the population of the study area regarding procedures and current knowledge about the trial vaccine. During April 9-August 15, 2015, STRIVE enrolled 8,673 participants, of whom 453 and 539 were also enrolled in the safety and immunogenicity substudies, respectively. As of April 28, 2016, no Ebola cases and no vaccine-related serious adverse events, which by regulatory definition include death, life-threatening illness, hospitalization or prolongation of hospitalization, or permanent disability, were reported in the study population. Although STRIVE will not produce an estimate of vaccine efficacy because of low case frequency as the epidemic was controlled, data on safety and immunogenicity will support decisions on licensure of rVSV-ZEBOV.The activities summarized in this report would not have been possible without collaboration with many U.S. and international partners (http://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/partners.html).

INTRODUCTION: This study focused on how first-time mothers decide or intend to decide with respect to the recommended childhood immunization schedule. METHODS: This was the baseline survey of a larger longitudinal survey. Data were collected between June and September 2014 from 200 first-time mothers in their second trimester of pregnancy to examine vaccine-related knowledge, perceptions, intentions, and information-seeking behavior. RESULTS: Data were analyzed between January and June 2015. Seventy-five percent planned to have their child receive all the vaccinations consistent with the recommended childhood immunization schedule. Although participants expressed interest in childhood vaccine information, most had not received information directly from a primary care provider. One third reported receiving such information from their obstetrician/gynecologist but only about half of those were "very satisfied" with the information they received. About 70% indicated they were not familiar with the recommended vaccination schedule and number of routinely recommended vaccines. Familiarity with common vaccine education messages varied widely. Women who indicated they were planning to delay one or more recommended vaccinations were most likely to rely on Internet searches for childhood vaccine information. CONCLUSIONS: Overall, respondents had relatively positive beliefs and perceptions regarding childhood vaccines, which were associated with intentions to get their newborn vaccinated as recommended. However, most who were planning to delay recommended vaccinations or were undecided relied primarily on socially available sources of vaccine information, rather than information provided by a healthcare professional. Improved access to vaccine information from healthcare professionals could foster better vaccine-related knowledge and favorably impact vaccination decisions.

INTRODUCTION: A primary mission of the U.S. Centers for Disease Control and Prevention's (CDC) is promoting immunization against seasonal influenza. As with most education efforts, CDC's influenza-related communications are often informed by formative research. METHODS: A qualitative meta-analysis of 29 unpublished, primarily qualitative CDC-sponsored studies related to flu and flu vaccination knowledge, attitudes and beliefs (KABs). The studies, undertaken between 2000 and 2013, involved focus groups, in-depth interviews, message testing and surveys. Some involved health care professionals, while others involved members of the public, including sub-populations at risk for severe illness. FINDINGS: The themes that emerged suggested progress in terms of KABs related to influenza and influenza vaccination, but also the persistence of many barriers to vaccine acceptance. With respect to the public, recurring themes included limited understanding of influenza and immunization recommendations, indications of greater sub-group recognition of the value of flu vaccination, continued resistance to vaccination among many, and overestimation of the effectiveness of non-vaccine measures. Seven cognitive facilitators of vaccination were identified in the studies along with six cognitive barriers. For health care providers, the analysis suggests greater knowledge and more favorable beliefs, but many misperceptions persist and are similar to those held by the public. KABs often differed by type or category of health care provider. CONCLUSIONS: The themes identified in this qualitative analysis illustrate the difficulty in changing KABs related to influenza and influenza vaccine, particularly on the scope and scale needed to greatly improve uptake. Even with an influenza pandemic and more vaccine options available, public and some health care provider perceptions and beliefs are difficult and slow to change. This meta-analysis does, however, provide important insights from previously unpublished information that can help those who are promoting influenza vaccination to health care providers, the general public and specific populations within the general population.

OBJECTIVE: The purpose of this study was to assess respondents' self-reported choices for vaccinating their young children; knowledge, attitudes, and beliefs (KABs) about vaccination; and communication with their child's vaccination provider. METHODS: A national telephone survey of 1500 parents of children aged 6 to 23 months was conducted in 2010. We calculated proportions of parents who had chosen-or planned-to refuse or delay 1 or more recommended vaccines, and proportions for responses to KABs and communication questions, stratified by vaccination choice (ie, refuse or delay). RESULTS: The response rate was 46%. Among the 96.6% of respondents (95% confidence interval [CI], 95.5%-97.4%; weighted n = 1453) who had chosen for their child to receive at least 1 vaccine, 80.6% (95% CI, 78.8%-83.0%) reported that their child had received all vaccines when recommended and 86.5% (95% CI, 84.7%-88.2%) reported that their child would receive remaining vaccines when recommended. Respondents who considered not following recommendations, but ultimately did, cited the physician's recommendation as the reason for vaccinating. Most vaccinators who reported past or planned deviations from recommendations cited only 1 vaccine that they would refuse and/or delay; all vaccines were mentioned. These parents reported approaching vaccination with serious concerns, while believing other parents did not. All parents cited "vaccine side effects" as their top question or concern. Almost all parents talked to a doctor or nurse about vaccines and, overall, satisfaction with communication was high. CONCLUSIONS: Communication about vaccines is important to most parents, but may be challenging for providers, because parental choices vary; thus, efforts to improve and support vaccine communication by providers should continue.

OBJECTIVE: To describe the vaccine-related attitudes, concerns, and information sources of US parents of young children. METHODS: We calculated weighted proportions and 95% confidence intervals for vaccine-related attitudes, concerns, and information sources of parents with at least 1 child aged 6 years or younger who participated in the 2009 HealthStyles survey. RESULTS: The overall response rate for the survey was 65% (4556 of 7004); 475 respondents were parents or guardians ("parents") of at least 1 child aged 6 years or younger. Among those respondents, nearly all (93.4%) reported that their youngest child had or would receive all recommended vaccines. The majority of parents reported believing that vaccines were important to children's health (79.8%) and that they were either confident or very confident in vaccine safety (79.0%). The vaccine-related concern listed most often by parents was a child's pain from the shots given in 1 visit (44.2%), followed by a child getting too many vaccines at 1 doctor's visit (34.2%). When asked to list their most important sources of information on vaccines, the most common response was a child's doctor or nurse (81.7%). CONCLUSIONS: To maintain and improve on the success of childhood vaccines in preventing disease, a holistic approach is needed to address parents' concerns in an ongoing manner. Listening and responding in ways and with resources that address specific questions and concerns could help parents make more informed vaccination decisions.

The United States has made tremendous progress in using vaccines to prevent serious, often infectious, diseases. But concerns about such issues as vaccines' safety and the increasing complexity of immunization schedules have fostered doubts about the necessity of vaccinations. We investigated parents' confidence in childhood vaccines by reviewing recent survey data. We found that most parents--even those whose children receive all of the recommended vaccines--have questions, concerns, or misperceptions about them. We suggest ways to give parents the information they need and to keep the US national vaccination program a success.

BACKGROUND: Little is known about the effects of increased parental vaccine safety concerns on physicians' vaccine communication attitudes and practices. PURPOSE: To assess among pediatricians and family medicine (FM) physicians: (1) prevalence of parental requests to deviate from recommended vaccine schedules; (2) responses to such requests; and (3) attitudes about the burden and success of vaccine communications with parents. METHODS: Survey of nationally representative samples of pediatricians and FM physicians (N=696) conducted during February to May 2009 with analysis in 2010. RESULTS: Response rates were 88% for pediatricians and 78% for FM physicians. Overall, 8% of physicians reported that ≥10% of parents refused a vaccine and 20% reported that ≥10% of parents requested to spread out vaccines in a typical month. More pediatricians than FM physicians reported always/often requiring parents to sign a form if they refused vaccination (53% vs 31%, p<0.0001); 64% of all physicians would agree to spread out vaccines in the primary series at least sometimes. When talking with parents with substantial concerns, 53% of physicians reported spending 10-19 minutes and 8% spending ≥20 minutes. Pediatricians were more likely than FM physicians to report their job less satisfying because of parental vaccine concerns (46% vs 21%, p<0.0001). Messages most commonly reported as "very effective" were personal statements such as what they would do for their own children. CONCLUSIONS: The burden of communicating with parents about vaccines is high, especially among pediatricians. Physicians report the greatest success convincing skeptical parents using messages that rely on their personal choices and experiences.
