RESUMO
Understanding how attitudes and beliefs about COVID-19 vaccination have changed over time is essential for identifying areas where targeted messaging and interventions can improve vaccination confidence and uptake. Using data from multiple waves of the nationally representative U.S. Census Bureau's Household Pulse Survey collected from January 2021 to May 2023, we assessed reasons for the non-vaccination of adults, adolescents, and children using the Health Belief Model as the framework for understanding behavior. Among unvaccinated adults, perceived vulnerability increased from 11.9% to 44.1%, attitudinal factors/mistrust increased from 28.6% to 53.4%, and lack of cue to action increased from 7.5% to 9.7% from January 2021 to May 2022. On the other hand, safety/efficacy concerns decreased from 74.0% to 60.9%, and logistical barriers to vaccination decreased from 9.1% to 3.4% during the same time period. Regarding reasons for non-vaccination of youth, perceived vulnerability increased from 32.8% to 40.0%, safety/efficacy concerns decreased from 73.9% to 60.4%, and lack of cue to action increased from 10.4% to 13.4% between September 2021 and May 2023. While safety/efficacy concerns and logistic barriers have decreased, increases in perceived vulnerability to COVID-19, mistrust, and lack of cues to action suggest that more efforts are needed to address these barriers to vaccination.
RESUMO
Given the increase in COVID-19 emergency department visits and hospitalizations during the winter of 2023-2024, identifying groups that have a high prevalence of COVID-19 cases, severity, and long-term symptoms can help increase efforts toward reducing disparities and prevent severe COVID-19 outcomes. Using data from the 2022 National Health Interview Survey (n = 27,651), we assessed the prevalence of COVID-19 outcomes (prior diagnosis, moderate/severe COVID-19, and long COVID) by sociodemographic characteristics and factors associated with each COVID-19 outcome. Approximately one third of adults reported a prior COVID-19 diagnosis (30.7%), while one half (51.6%) who had COVID-19 reported moderate or severe symptoms, and one fifth (19.7%) who had COVID-19 symptoms reported long COVID. The following were associated with higher odds of moderate/severe COVID-19 and long COVID: havinga high-risk condition (aOR = 1.20, OR = 1.52); having anxiety or depression (OR = 1.46, OR = 1.49); having a disability (OR = 1.41, OR = 1.60); and having a food insecurity (OR = 1.37, OR = 1.50) compared to a lack of these conditions. Having two or more COVID-19 vaccinations was associated with lower odds of a COVID-19 diagnosis (OR = 0.75), moderate/severe COVID-19 (OR = 0.86), and long COVID (OR = 0.82). Improving vaccination coverage and reducing disparities in COVID-19 outcomes could advance health equities and protect against future resurgence of disease.
RESUMO
Understanding the association between booster vaccination and COVID-19 outcomes can help strengthen post-pandemic messaging and strategies to increase vaccination and reduce severe and long-term consequences of COVID-19. Using the Household Pulse Survey data collected from U.S. adults from 9 December 2022 to 13 February 2023 (n = 214,768), this study assessed the relationship between COVID-19 booster vaccination and COVID-19 outcomes (testing positive for COVID-19, moderate/severe COVID-19, and long COVID). Disparities were found in COVID-19 outcomes (e.g., testing positive for COVID-19, moderate/severe COVID-19, and long COVID) by sociodemographic characteristics, region of residence, food insecurity status, mental health status, disability status, and housing type. Receipt of a COVID-19 booster vaccination was negatively associated with testing positive for COVID-19 (aOR = 0.75, 95%CI: 0.72,0.79), having moderate/severe COVID-19 (aOR = 0.92, 95%CI: 0.88, 0.97), or having long COVID (aOR = 0.86 (0.80, 0.91)). Even among those who tested positive for COVID-19, those who received the booster vaccine were less likely to have moderate/severe COVID-19 and less likely to have long COVID. Communicating the benefits of COVID-19 booster vaccination, integrating vaccination in patient visits, and reducing access barriers can increase vaccination uptake and confidence for all individuals and protect them against the severe negative outcomes of COVID-19.
RESUMO
INTRODUCTION: Understanding changes in vaccine hesitancy, overall and by sociodemographic characteristics, may highlight sub-populations for whom more intensive efforts are needed to increase vaccine uptake and confidence. METHODS: We analyzed data using the CDC's Research and Development Survey (RANDS), a nationally representative survey of U.S. adults ≥18 years, collected from 17 May 2021-30 June 2021 (n = 5,458) and 3 November 2022-12 December 2022 (n = 6,821). We assessed changes in vaccine hesitancy, changes in vaccine attitudes and attitudes, and factors associated with hesitancy toward both vaccines in general and COVID-19 vaccines among a nationally representative sample of U.S. adults. RESULTS: Although COVID-19 vaccination (≥1 dose) increased from 67.2% (2021) to 74.7% (2022), COVID-19 vaccine hesitancy increased from 40.7% to 44.6% during the same period. During the same period, hesitancy toward both COVID-19 vaccines and vaccines in general increased among those who were aged ≥65 years and who were non-Hispanic White. However, COVID-19 vaccine hesitancy decreased among non-Hispanic Black adults. Current or former smokers were more hesitant toward vaccines in general (aPR = 1.13, 95%CI: 1.03-1.24) and toward COVID-19 vaccines (aPR = 1.08, 95%CI: 1.01-1.16) compared to never smokers. Among adults who did not receive any COVID-19 vaccines, COVID-19 vaccine hesitancy increased from 86.6% in 2021 to 92.4% in 2022. Furthermore, belief in the overall social benefit of the COVID-19 vaccine decreased from 47.5% to 25.1%. CONCLUSION: This study highlights concerning trends in vaccine hesitancy and uptake of the COVID-19 and other recommended vaccines. We found that some high-risk groups (e.g. smokers) and population subgroups have become more vaccine hesitant, suggesting the need for improved and intensified strategies to increase vaccine confidence and uptake. Future research may focus on qualitative inquiry to understand specific concerns and determinants contributing to increased hesitancy among these groups to help inform interventions and communication campaigns to support vaccination.
COVID-19 vaccine hesitancy increased from 40.7% in 2021 to 44.6% in 2022.During the same period, hesitancy regarding both the COVID-19 vaccine and vaccines in general increased among those who were ≥65 years and non-Hispanic White while hesitancy toward COVID-19 vaccines decreased among non-Hispanic Black adults.Belief in the overall social benefit of the COVID-19 vaccine decreased from 47.5% to 25.1%, suggesting need to frame messaging on benefits such as protection from severe disease outcomes.

PURPOSE: Understanding disparities in COVID-19 outcomes, overall and stratified by vaccination status, is important for developing targeted strategies to increase vaccination coverage and protect adolescents from COVID-19. DESIGN: The 2022 National Health Interview Survey (NHIS) is a cross-sectional nationally representative household survey of U.S. adults. SETTING: A probability sample of households in the U.S. SAMPLE: One child aged 12-17 years is randomly selected from each family in the household. A knowledgeable adult (eg, parent or guardian), responds on behalf of the child through an in-person interview (response rate = 49.9%). MEASURES: Input measures-sociodemographic characteristics and COVID-19 vaccination status; output measures-ever had COVID-19, moderate/severe COVID-19, long COVID. ANALYSIS: Prevalence of COVID-19 outcomes was assessed for adolescents aged 12-17 years. Factors associated with each COVID-19 outcome were assessed with multivariable logistic regression analyses. RESULTS: Among 2758 adolescents aged 12-17 years in 2022, 60.5% had received ≥1 dose of COVID-19 vaccine, 30.2% had ever been diagnosed by a doctor that they had COVID-19, 29.5% had moderate/severe COVID-19, and 6.2% had long COVID. Adolescents who were vaccinated with ≥1 dose were less likely to be diagnosed with COVID-19 (aOR = .79) and less likely to have long COVID (aOR = .30). CONCLUSION: Targeted messaging to highlight the importance of early treatment, the harms of long COVID-19, and the benefits of vaccination in protecting against long-term effects may be necessary to ensure that all adolescents and their families are adequately protected.

INTRODUCTION: Being up-to-date with all recommended vaccines is needed to protect children from vaccine preventable diseases. Understanding vaccination patterns is needed to develop messaging and strategies to increase vaccination uptake and confidence. METHODS: Data from the 2011 to 2021 National Immunization Surveys was used to assess trends and disparities in vaccination patterns, zero vaccination status, and up-to-date status of U.S. children by 19-35 months. RESULTS: From 2011 to 2021, adherence to the recommended schedule using the stringent definition increased from 35.7 % to 52.2 % (p < 0.01), adherence to the alternate schedule decreased from 28.2 % to 15.1 % (p < 0.01), and proportion of children who were not up-to-date decreased from 49.0 % to 33.3 % (p < 0.01). However, the proportion of children who had zero vaccinations did not change from 2011 (0.9 %) to 2021 (0.9 %; p = 0.08). In 2021, children 19-23 months were less likely to follow the recommended schedule than children 24-29 months (49.2 % compared to 56.4 %, p < 0.01). Adherence to the recommended schedule among children 19-23 months decreased in 2021 compared to 2020 overall and for some subpopulations (e.g. those with non-Hispanic (NH) Black parents (33.2 % compared to 44.9 %, p < 0.01). Furthermore, it was lowest among children of NH Black parents living at or below the federal poverty level (31.2 %) compared to their respective NH White counterparts (43.6 %, p < 0.01). CONCLUSIONS: While there were overall increases in adherence to the recommended schedule from 2011 to 2021, a sustained catch-up program is needed to prevent missed vaccinations and achieve equitable vaccination coverage for all children.

Long COVID and its symptoms have not been examined in different subpopulations of U.S. adults. Using the 2022 BRFSS (n = 445,132), we assessed long COVID and each symptom by sociodemographic characteristics and health-related variables. Multivariable logistic regression was conducted to examine factors associated with long COVID and the individual symptoms. Prevalence differences were conducted to examine differences in long COVID by vaccination status. Overall, more than one in five adults who ever had COVID-19 reported symptoms consistent with long COVID (21.8%). The most common symptom was tiredness or fatigue (26.2%), followed by difficulty breathing or shortness of breath (18.9%), and loss of taste or smell (17.0%). Long COVID was more common among adults under 65 years, women, American Indian or Alaska Native or other/multi race group, smokers, and people with a disability, depression, overweight or obesity compared to their respective counterparts. The prevalence of long COVID was higher among unvaccinated adults (25.6%) than vaccinated adults (21.6%) overall, and for 20 of 32 subgroups assessed. These findings underscore the benefits of vaccination, the importance of early treatment, and the need to better inform health care resource allocation and support services for those experiencing long COVID.
RESUMO
Understanding the extent of coronavirus disease 2019 (COVID-19) nonvaccination attributable to vaccine hesitancy versus other barriers can help prioritize approaches for increasing vaccination uptake. Using data from the Centers for Disease Control and Prevention's Research and Development Survey, a nationally representative survey fielded from May 1 to June 30, 2021 (n = 5,458), we examined the adjusted population attribution fraction (PAF) of COVID-19 vaccine hesitancy attributed to nonvaccination according to sociodemographic characteristics and health-related variables. Overall, the adjusted PAF of nonvaccination attributed to vaccine hesitancy was 76.1%. The PAF was highest among adults who were ≥50 years of age (87.9%), were non-Hispanic White (83.7%), had a bachelor's degree or higher (82.7%), had an annual household income of at least $75,000 (85.5%), were insured (82.4%), and had a usual place for health care (80.7%). The PAF was lower for those who were current smokers (65.3%) compared with never smokers (77.9%), those who had anxiety or depression (65.2%) compared with those who did not (80.1%), and those who had a disability (64.5%) compared with those who did not (79.2%). Disparities in PAF suggest areas for prioritization of efforts for intervention and development of messaging campaigns that address all barriers to uptake, including hesitancy and access, to advance health equity and protect individuals from COVID-19.

BACKGROUND: Adults who are hesitant toward routinely recommended vaccines for adults may also be hesitant toward COVID-19 vaccines. However, the distribution and differences in hesitancy between routinely recommended vaccines and COVID-19 vaccines, and the association of hesitancy regarding routinely recommended vaccines and hesitancy with COVID-19 vaccination status and intent, is unknown. METHODS: Using the Research and Development Survey (RANDS) during COVID-19, Round 3, a probability-sampled, nationally representative, web and phone survey fielded from May 17 - June 30, 2021 (n = 5,434), we examined the distribution and difference in prevalence of hesitancy towards COVID-19 and vaccines in general, beliefs associated with vaccine hesitancy, and factors impacting plans to be vaccinated against COVID-19. RESULTS: Reported hesitancy towards COVID-19 vaccines (42.2%) was 6-percentage points higher than hesitancy towards vaccines in general (35.7%). Populations who were most hesitant toward COVID-19 vaccines were younger adults, non-Hispanic Black adults, adults with lower education or income, and adults who were associated with a religion. Beliefs in the social benefit and the importance of vaccination, and the belief that COVID-19 vaccines lower risk for infection, were strongly associated with COVID-19 vaccination and intent to be vaccinated. CONCLUSIONS: Vaccine hesitancy for both COVID-19 vaccines and vaccines in general is common. Health providers and public health officials should utilize strategies to address vaccine hesitancy, including providing strong clear recommendations for needed vaccines, addressing safety and effectiveness concerns, and utilizing trusted messengers such as religious and community leaders to improve vaccine confidence.

Cigar smoking remains a public health issue in the United States (U.S.), with a heterogeneous prevalence based on sociodemographic characteristics. Nationally representative data suggest changes in cigar smoking over time, with some evidence for sociodemographic differences. Using data from the 2002-2019 National Survey on Drug Use and Health (NSDUH), the prevalence of past-30-day cigar smoking was examined overall and stratified by sociodemographic characteristics; joinpoint regression examined the trends. Logistic regression analyses identified the correlates of cigar smoking using 2020 NSDUH data. From 2002 to 2004, the prevalence of cigar smoking remained stable (5.33-5.73%), but declined from 2004 to 2019 (5.73-4.29%). Cigar smoking declined in some periods between 2002-2019 among the non-Hispanic White, Hispanic, ages 12-17, ages 18-20, ages 21-25, age ≥ 35, and male subgroups, but remained unchanged among the non-Hispanic Other, ages 26-34, and female subgroups. Cigar smoking increased among non-Hispanic Black persons overall from 2002 to 2019 (6.67-8.02%). Past-30-day cigarette smoking and drug or alcohol use disorder was associated with an increased likelihood of cigar use, while female sex was associated with a decreased likelihood of cigar use, across all age groups. Though a decline in the prevalence of past-30-day cigar smoking is seen in the general population, the same is not evident among all sociodemographic subgroups. Our findings have the potential to inform tobacco cessation efforts within clinical practice, as well as regulatory efforts to reduce cigar use.

Objectives. To identify promising practices for implementing COVID-19 vaccination sites. Methods. The Centers for Disease Control and Prevention (CDC) and Federal Emergency Management Agency (FEMA) assessed high-throughput COVID-19 vaccination sites across the United States, including Puerto Rico, after COVID-19 vaccinations began. Site assessors conducted site observations and interviews with site staff. Qualitative data were compiled and thematically analyzed. Results. CDC and FEMA conducted 134 assessments of high-throughput vaccination sites in 25 states and Puerto Rico from February 12 to May 28, 2021. Promising practices were identified across facility, clinical, and cross-cutting operational areas and related to 6 main themes: addressing health equity, leveraging partnerships, optimizing site design and flow, communicating through visual cues, using quick response codes, and prioritizing risk management and quality control. Conclusions. These practices might help planning and implementation of future vaccination operations for COVID-19, influenza, and other vaccine-preventable diseases. Public Health Implications. These practices can be considered by vaccination planners and providers to strengthen their vaccination site plans and implementation of future high-throughput vaccination sites.

Background: With people across the United States spending increased time at home since the emergence of COVID-19, housing characteristics may have an even greater impact on health. Therefore, we assessed associations between household conditions and COVID-19 experiences. Methods: We used data from two nationally representative surveys: the Tufts Equity Study (TES; n = 1449 in 2021; n = 1831 in 2022) and the Household Pulse Survey (HPS; n = 147,380 in 2021; n = 62,826 in 2022). In the TES, housing conditions were characterized by heating/cooling methods; smoking inside the home; visible water damage/mold; age of housing unit; and self-reported concern about various environmental factors. In TES and HPS, household size was assessed. Accounting for sampling weights, we examined associations between each housing exposure and COVID-19 outcomes (diagnosis, vaccination) using separate logistic regression models with covariates selected based on an evidence-based directed acyclic graph. Results: Having had COVID-19 was more likely among people who reported poor physical housing condition (odds ratio [OR] = 2.32; 95% confidence interval [CI] = 1.17-4.59; 2021), visible water damage or mold/musty smells (OR = 1.50; 95% CI = 1.10-2.03; 2022), and larger household size (5+ versus 1-2 people; OR = 1.53, 95% CI = 1.34-1.75, HPS 2022). COVID-19 vaccination was less likely among participants who reported smoke exposure inside the home (OR = 0.53; 95% CI = 0.31-0.90; 2022), poor water quality (OR = 0.42; 95% CI = 0.21-0.85; 2021), noise from industrial activity/construction (OR = 0.44; 95% CI = 0.19-0.99; 2022), and larger household size (OR = 0.57; 95% CI = 0.46-0.71; HPS 2022). Vaccination was also positively associated with poor indoor air quality (OR = 1.96; 95% CI = 1.02-3.72; 2022) and poor physical housing condition (OR = 2.27; 95% CI = 1.01-5.13; 2022). Certain heating/cooling sources were associated with COVID-19 outcomes. Conclusions: Our study found poor housing conditions associated with increased COVID-19 burden, which may be driven by systemic disparities in housing, healthcare, and financial access to resources during the COVID-19 pandemic.
RESUMO
INTRODUCTION: Despite recommendations for COVID-19 primary series completion and booster doses for children and adolescents, coverage has been less than optimal, particularly in some subpopulations. This study explored disparities in childhood/adolescent COVID-19 vaccination, parental intent to vaccinate their children and adolescents, and reasons for non-vaccination in the US. METHODS: Using the U.S. Census Bureau's Household Pulse Survey (HPS), we analyzed households with children aged <18 years using data collected from September 14 to November 14, 2022 (n = 44,929). Child and adolescent COVID-19 vaccination coverage (≥1 dose, completed primary series, and booster vaccination) and parental intentions toward vaccination were assessed by sociodemographic characteristics. Factors associated with child and adolescent vaccination coverage were examined using multivariable regression models. Reasons for non-vaccination were assessed overall, by the child's age group and respondent's age group. RESULTS: Overall, approximately half (50.1%) of children aged < 18 years were vaccinated against COVID-19 (≥1 dose). Completed primary series vaccination was 44.2% among all children aged <18 years. By age group, completed primary series was 13.2% among children <5 years, 43.9% among children 5-11 years, and 63.3% among adolescents 12-17 years. Booster vaccination among those who completed the primary series was 39.1% among children 5-11 years and 55.3% among adolescents 12-17 years. Vaccination coverage differed by race/ethnicity, educational attainment, household income, region, parental COVID-19 vaccination status, prior COVID-19 diagnosis, child's age group, and parental age group. Parental reluctance was highest for children aged <5 years (46.8%). Main reasons for non-vaccination among reluctant parents were concerns about side effects (53.3%), lack of trust in COVID-19 vaccines (48.7%), and the belief that children do not need a COVID-19 vaccine (38.8%). CONCLUSION: Disparities in COVID-19 vaccination coverage among children and adolescents continue to exist. Further efforts are needed to increase COVID-19 primary series and booster vaccination and parental confidence in vaccines.

INTRODUCTION: Despite recommendations for influenza and COVID-19 vaccines, studies have documented gaps and disparities in vaccination coverage for adults and adolescents. Understanding the proportion and demographics of those unvaccinated against influenza and/or COVID-19 is important for tailoring appropriate messaging and strategies to increase confidence and uptake. METHODS: Using the 2021 National Health Interview Survey (NHIS), we assessed the prevalence of four vaccination patterns (exclusive influenza vaccination, exclusive COVID-19 vaccination, dual influenza and COVID-19 vaccination, and neither vaccination) by sociodemographic and other characteristics among adults and adolescents 12-17 years. Adjusted multivariable regression analyses were conducted to examine factors associated with each of the four vaccination categories among adults and adolescents. RESULTS: In 2021, 42.5% of adults and 28.3% of adolescents received both influenza and COVID-19 vaccines, while approximately a quarter (22.4%) of adults and a third (34.0%) of adolescents did not receive either vaccine. Among adults and adolescents, 6.0% and 11.4% were exclusively vaccinated against influenza and 29.1% and 26.4% were exclusively vaccinated against COVID-19, respectively. Among adults, exclusive COVID-19 or dual vaccination was more likely to be associated with older age, non-Hispanic multi/other race, and having a college degree compared to their respective counterparts. Exclusive influenza or neither vaccination was more likely to be associated with younger age, having a high school diploma or less, living below the poverty level, and having a previous COVID-19 diagnosis. CONCLUSION: During the COVID-19 pandemic, approximately two-thirds of adolescents and three-fourths of adults received exclusive influenza or COVID-19 vaccines or both vaccines in 2021. Vaccination patterns differed by sociodemographic and other characteristics. Promoting confidence in vaccines and reducing barriers to access is needed to protect individuals and families from severe health consequences of vaccine-preventable diseases. Being up-to-date with all recommended vaccinations can prevent a future resurgence of hospitalizations and cases.Key messages42.5% of adults and 28.3% of adolescents received both influenza and COVID-19 vaccines in 2021, while approximately a quarter (22.4%) of adults and a third (34.0%) of adolescents did not receive either vaccine; 6.0% of adults and 11.4% of adolescents were exclusively vaccinated against influenza and 29.1% of adults and 26.4% of adolescents were exclusively vaccinated against COVID-19.Among adults, exclusive COVID-19 vaccination or dual vaccination was more likely to be associated with older age, non-Hispanic multi/other race, and having a college degree or higher compared to their respective counterparts; exclusive influenza vaccination or neither vaccination was more likely to be associated with younger age, having a high school diploma or less, living below poverty level, and having a previous COVID-19 diagnosis compared to their respective counterparts.Promoting confidence in vaccines and reducing barriers to access is needed to protect individuals and families from severe health consequences of vaccine-preventable diseases. Being up-to-date with all recommended vaccinations can prevent a future resurgence of hospitalizations and cases, especially as new variants emerge.

BACKGROUND: The role of vaccine hesitancy on influenza vaccination is not clearly understood. Low influenza vaccination coverage in U.S. adults suggests that a multitude of factors may be responsible for under-vaccination or non-vaccination including vaccine hesitancy. Understanding the role of influenza vaccination hesitancy is important for targeted messaging and intervention to increase influenza vaccine confidence and uptake. The objective of this study was to quantify the prevalence of adult influenza vaccination hesitancy (IVH) and examine association of IVH beliefs with sociodemographic factors and early-season influenza vaccination. METHODS: A four-question validated IVH module was included in the 2018 National Internet Flu Survey. Weighted proportions and multivariable logistic regression models were used to identify correlates of IVH beliefs. RESULTS: Overall, 36.9% of adults were hesitant to receive an influenza vaccination; 18.6% expressed concerns about vaccination side effects; 14.8% personally knew someone with serious side effects; and 35.6% reported that their healthcare provider was not the most trusted source of information about influenza vaccinations. Influenza vaccination ranged from 15.3 to 45.2 percentage points lower among adults self-reporting any of the four IVH beliefs. Being female, age 18-49 years, non-Hispanic Black, having high school or lower education, being employed, and not having primary care medical home were associated with hesitancy. CONCLUSIONS: Among the four IVH beliefs studied, being hesitant to receiving influenza vaccination followed by mistrust of healthcare providers were identified as the most influential hesitancy beliefs. Two in five adults in the United States were hesitant to receive an influenza vaccination, and hesitancy was negatively associated with vaccination. This information may assist with targeted interventions, personalized to the individual, to reduce hesitancy and thus improve influenza vaccination acceptance.

Understanding parental decision-making about vaccinating their children for COVID-19 is essential to promoting uptake. We conducted an online survey between April 23-May 3, 2021, among a national sample of U.S. adults to assess parental willingness to vaccinate their child(ren). We also examined associations between parental intentions to VACCINATE their children for COVID-19 and conspiracy theory beliefs, trusted information sources, trust in public authorities, and perceptions regarding the responsibility to be vaccinated. Of 257 parents of children under 18 years that responded, 48.2% reported that they would vaccinate their children, 25.7% were unsure, and 26.1% said they would not vaccinate. After adjusting for covariates, each one-point increase in the Vaccine Conspiracy Beliefs Scale was associated with 25% lower odds of parents intending to vaccinate their children compared to those who did not intend to (adjusted odds ratio (AOR) = 0.75, 95% confidence interval (CI): 0.64-0.88). Parents that perceived an individual and societal responsibility to be vaccinated were more likely to report that they intended to vaccinate their children compared to those that did not intend to vaccinate their children (AOR = 5.65, 95% CI: 2.37-13.44). Findings suggest that interventions should focus on combatting conspiracy beliefs, promoting accurate and trusted information sources, and creating social norms emphasizing shared responsibility for vaccination.

We assessed COVID-19 booster vaccination coverage and reasons for non-receipt using a large, nationally representative survey (June - August, 2022). Booster vaccination coverage was 71.7% among adults, 36.8% among children, and 51.6% among adolescents. Reasons for non-receipt included the belief that it was not necessary and lack of time for vaccination. All eligible individuals should receive the updated booster vaccines as soon as possible to protect against new variants of COVID-19.

BACKGROUND: COVID-19 vaccines are now available under Emergency Use Authorization for children ages 6 months to 5 years. We examined parents' intentions to vaccinate their children under the age of 5 years and assessed whether their confidence in making an informed decision about vaccination (decision self-efficacy) was associated with these intentions. METHOD: We conducted a cross-sectional online survey of U.S. parents between 23 March and 5 April 2022. We examined associations between parental intention to vaccinate their young children (
RESUMO
INTRODUCTION: The COVID-19 pandemic affected the lives of military members and their families, with over 400,000 cases among U.S. military members since the start of the pandemic. The objective of this study is to examine and compare COVID-19 vaccination coverage of military members (active duty and Reserve/National Guard) and their family members (spouses, children, and adolescents) to that of their civilian counterparts using a large, nationally representative study. METHODS: Data from March 2 to May 9, 2022, of the Household Pulse Survey were analyzed for this study (n = 207,758). COVID-19 vaccination status (≥1 dose) was assessed for military members and their spouses, civilians, and children (aged 5 to 11 and 12 to 17 years) from both military and civilian families. Differences between military members, spouses, and their children compared to civilian adults and children were assessed using chi-squared and t-tests. Multivariable logistic regression was used to examine the association between military status and COVID-19 vaccination after controlling for sociodemographic characteristics. Reasons for not getting vaccinated for adults and children from military and civilian families were assessed. RESULTS: Compared to civilian adults and adjusted for sociodemographic characteristics, military members were more likely to be vaccinated (adjusted prevalence ratio = 1.07, 95% CI: 1.01-1.13). Vaccination coverage between active duty and civilian adults differed by subgroups. For example, among military members, COVID-19 vaccination coverage decreased with increasing age, from 87.5% among those aged 18 to 39 years to 56.0% among those aged ≥55 years. In contrast, among civilian adults, vaccination coverage increased with increasing age, from 78.5% among those aged 18 to 39 years to 91.2% among those aged ≥55 years. Military members were also less likely to be vaccinated than their civilian counterparts if they were Hispanic (68.5% vs. 85.2%), had a Bachelor's degree or higher (87.5% vs. 93.8%), or had $100,000 or more in annual household income (76.7% vs. 92.6%). Military members who had anxiety or depression (70.1%) were less likely to be vaccinated compared to civilian adults (84.4%). Military spouses (74.4%) were less likely to be vaccinated than civilian adults (84.7%). Children and adolescents who were homeschooled (35.1%) or had no preventive checkups in the past year (32.4%) were less likely to be vaccinated than their respective counterparts (52.5% and 54.0%, respectively). Military adults compared to civilian adults were more likely to report lack of trust in the government (47.5% vs. 35.2%) and, for children/adolescents, the belief that the vaccine is not needed (42.1% vs. 28.1%) as reasons for non-vaccination. CONCLUSIONS: Despite vaccine mandates and the high vaccination coverage found among the majority of military members, disparities exist in some subgroups. Educational interventions and increased communication from trusted leaders, such as medical providers and commanders, could increase confidence in vaccines among military families. Ensuring access to vaccines, empowering healthcare providers to recommend vaccines, and reminding parents of missed vaccinations or preventive checkups can help improve vaccination coverage. Achieving high vaccination among military members and their families is essential in protecting those in the forefront of the pandemic response and promoting the safety and security of the nation.
RESUMO
OBJECTIVES: To estimate trends in, and factors associated with, vaccination patterns and up-to-date immunization status of U.S. children by 19 to 35 months of age. METHODS: Data from the 2015 to 2020 National Immunization Surveys were used to assess trends in vaccination patterns, up-to-date status, and zero vaccination status of U.S. children by 19-35 months. Vaccination patterns were categorized as: 1) recommended, 2) alternate, or 3) unknown or unclassifiable. Multivariable analyses were conducted to examine factors associated with each vaccination pattern and up-to-date status for all recommended vaccines. RESULTS: From 2015 to 2020, the proportion of U.S. children completing the recommended schedule increased from 62.5% to 69.4%, alternative schedule decreased from 21.6% to 16.2%, and unknown or unclassifiable schedules decreased from 15.9% to 14.3%. In addition, being not up-to-date decreased from 39.7% to 35.6%. There was no change in the percentage of children receiving zero vaccinations from 2015 to 2020 (0.9% to 0.9%). Respondents with lower household income or who were uninsured were more likely to follow an alternate or unknown/unclassifiable schedule, or not be up-to-date with vaccines. CONCLUSION: Following any schedule other than the recommended schedule was associated with not being up-to-date on immunizations. Increased efforts to catch up on recommended vaccines is important for protecting children's health. Further efforts should be made to improve timely adherence to recommended vaccination schedules, particularly among populations with the largest disparities in coverage through a tailored approach to increase confidence in and access to vaccines.
