Project description:ObjectivesNational data on COVID-19 vaccination coverage among pregnant women are limited. We assessed COVID-19 vaccination coverage and intent, factors associated with COVID-19 vaccination, reasons for nonvaccination, and knowledge, attitudes, and beliefs related to COVID-19 illness and vaccination among pregnant women in the United States.MethodsData from an opt-in internet panel survey of pregnant women conducted March 31-April 16, 2021, assessed receipt of ≥1 dose of any COVID-19 vaccine during pregnancy. The sample included 1516 women pregnant any time during December 1, 2020-April 16, 2021, who were not fully vaccinated before pregnancy. We used multivariable logistic regression to determine variables independently associated with receipt of COVID-19 vaccine.ResultsAs of April 16, 2021, 21.7% of pregnant women had received ≥1 dose of COVID-19 vaccine during pregnancy, 24.0% intended to receive a vaccine, 17.2% were unsure, and 37.1% did not intend to receive a vaccine. Pregnant women with (vs without) a health care provider recommendation (adjusted prevalence ratio [aPR] = 4.86), those who lived (vs not) with someone with a condition that could increase risk for serious medical complications of COVID-19 (aPR = 2.11), and those who had received (vs not) an influenza vaccination (aPR = 2.35) were more likely to receive a COVID-19 vaccine. Common reasons for nonvaccination included concerns about safety risk to baby (37.2%) or self (34.6%) and about rapid vaccine development (29.7%) and approval (30.9%).ConclusionsOur findings indicate a continued need to emphasize the benefits of COVID-19 vaccination during pregnancy and to widely disseminate the recommendations of the Centers for Disease Control and Prevention and other clinical professional societies for all pregnant women to be vaccinated.

Project description:Wearing a facemask can help to decrease the transmission of COVID-19. We investigated self-reported mask use among subjects aged 18 years and older participating in the COVID-19 Community Research Partnership (CRP), a prospective longitudinal COVID-19 surveillance study in the mid-Atlantic and southeastern United States. We included those participants who completed ≥5 daily surveys each month from December 1, 2020 through August 31, 2021. Mask use was defined as self-reported use of a face mask or face covering on every interaction with others outside the household within a distance of less than 6 feet. Participants were considered vaccinated if they reported receiving ≥1 COVID-19 vaccine dose. Participants (n = 17,522) were 91% non-Hispanic White, 68% female, median age 57 years, 26% healthcare workers, with 95% self-reported receiving ≥1 COVID-19 vaccine dose through August 2021; mean daily survey response was 85%. Mask use was higher among vaccinated than unvaccinated participants across the study period, regardless of the month of the first dose. Mask use remained relatively stable from December 2020 through April (range 71-80% unvaccinated; 86-93% vaccinated) and declined in both groups beginning in mid-May 2021 to 34% and 42% respectively in June 2021; mask use increased again since July 2021. Mask use by all was lower during weekends and on Christmas and Easter, regardless of vaccination status. Independent predictors of higher mask use were vaccination, age ≥65 years, female sex, racial or ethnic minority group, and healthcare worker occupation, whereas a history of self-reported prior COVID-19 illness was associated with lower use.

Project description:Stagnating COVID-19 vaccination rates and vaccine hesitancy remain a threat to public health. Improved strategies for real-time tracking and estimation of population-level behavior regarding vaccinations are needed. The aim of this study was to evaluate whether online search trends for COIVD-19 and influenza mirror vaccination rates. State-level weekly fraction of online searches for top vaccination-related search terms and CDC vaccination data were obtained from June 1, 2020, to May 31, 2021. Next, trends in online search and vaccination data for COVID-19 and influenza were analyzed for visual and quantitative correlation patterns using Spearman's rank correlation analysis. Online searches in the US for COVID-19 vaccinations increased 2.71-fold (95% CI: 1.98-3.45) in the 4 weeks after the FDA emergency authorization compared to the precedent 4 weeks. In March-April 2021, US online searches reached a plateau that was followed by a decline of 83.3% (95% CI: 31.2%-135.3%) until May 31, 2021. The timing of peaks in online searches varied across US states. Online searches were strongly correlated with vaccination rates (r=0.71, 95% CI: 0.45 - 0.87), preceding actual reported vaccination rates in 44 of 51 states. Online search trends preceded vaccination trends by a median of 3.0 weeks (95% CI: 2.0-4.0 weeks) across all states. For influenza vaccination searches, seasonal peaks in September-October between 2016-2020 were noted. Influenza search trends highly correlated with the timing of actual vaccinations for the 2019-2020 (r=0.82, 95% CI: 0.64 - 0.93) and 2020-2021 season (r=0.91, 95% CI: 0.78 - 0.97). Search trends and real-world vaccination rates are highly correlated. Temporal alignment and correlation levels were higher for influenza vaccinations; however, only online searches for COVID-19 vaccination preceded vaccination trends. These findings indicate that US online search data can potentially guide public health efforts, including policy changes and identifying geographical areas to expand vaccination campaigns.

Project description:BackgroundPregnant and postpartum women are at increased risk for severe illness from COVID-19. We assessed COVID-19 vaccination coverage, intent, and attitudes among women of reproductive age overall and by pregnancy status in the United States.MethodsData from the National Immunization Survey Adult COVID Module collected during April 22-November 27, 2021, were analyzed to assess COVID-19 vaccination (receipt of ≥1 dose), intent for vaccination, and attitudes towards vaccination among women aged 18-49 years overall and by pregnancy status (trying to get pregnant, currently pregnant, breastfeeding, and not trying to get pregnant or currently pregnant or breastfeeding). Logistic regression and predictive marginals were used to generate unadjusted and adjusted prevalence ratios (PRs and aPRs). Trend analyses were conducted to assess monthly changes in vaccination and intent.ResultsOur analyses included 110,925 women aged 18-49 years. COVID-19 vaccination coverage (≥1 dose) was 63.2% overall (range from 53.3% in HHS Region 4 to 76.5% in HHS Region 1). Vaccination coverage was lowest among pregnant women (45.1%), followed by women who were trying to get pregnant (49.5%), women who were breastfeeding (51.5%), and all other women (64.9%). Non-Hispanic (NH) Black women who were pregnant or breastfeeding had significantly lower vaccination coverage (aPR: 0.74 and 0.66, respectively) than NH White women.DiscussionOur findings are consistent with other studies showing lower vaccination coverage among pregnant individuals, with substantially lower vaccination coverage among NH Black women who are pregnant or breastfeeding. Given the overlapping and disproportionate risks of COVID-19 and maternal mortality among Black women, it is critical that COVID-19 vaccination be strongly recommended for these populations and all women of reproductive age. Healthcare and public health providers may take advantage of every opportunity to encourage vaccination and enlist the assistance of community leaders, particularly in communities with low vaccination coverage.

Project description:Vaccination of pregnant women with influenza vaccine and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) can decrease the risk for influenza and pertussis among pregnant women and their infants. The Advisory Committee on Immunization Practices (ACIP) recommends that all women who are or might be pregnant during the influenza season receive influenza vaccine, which can be administered at any time during pregnancy (1). ACIP also recommends that women receive Tdap during each pregnancy, preferably during the early part of gestational weeks 27-36 (2,3). Despite these recommendations, vaccination coverage among pregnant women has been found to be suboptimal with racial/ethnic disparities persisting (4-6). To assess influenza and Tdap vaccination coverage among women pregnant during the 2019-20 influenza season, CDC analyzed data from an Internet panel survey conducted during April 2020. Among 1,841 survey respondents who were pregnant anytime during October 2019-January 2020, 61.2% reported receiving influenza vaccine before or during their pregnancy, an increase of 7.5 percentage points compared with the rate during the 2018-19 season. Among 463 respondents who had a live birth by their survey date, 56.6% reported receiving Tdap during pregnancy, similar to the 2018-19 season (4). Vaccination coverage was highest among women who reported receiving a provider offer or referral for vaccination (influenza = 75.2%; Tdap = 72.7%). Compared with the 2018-19 season, increases in influenza vaccination coverage were observed during the 2019-20 season for non-Hispanic Black (Black) women (14.7 percentage points, to 52.7%), Hispanic women (9.9 percentage points, to 67.2%), and women of other non-Hispanic (other) races (7.9 percentage points, to 69.6%), and did not change for non-Hispanic White (White) women (60.6%). As in the 2018-19 season, Hispanic and Black women had the lowest Tdap vaccination coverage (35.8% and 38.8%, respectively), compared with White women (65.5%) and women of other races (54.0%); in addition, a decrease in Tdap vaccination coverage was observed among Hispanic women in 2019-20 compared with the previous season. Racial/ethnic disparities in influenza vaccination coverage decreased but persisted, even among women who received a provider offer or referral for vaccination. Consistent provider offers or referrals, in combination with conversations culturally and linguistically tailored for patients of all races/ethnicities, could increase vaccination coverage among pregnant women in all racial/ethnic groups and reduce disparities in coverage.

Project description:The response to the COVID-19 pandemic in the U.S prompted abrupt and dramatic changes to social contact patterns. Monitoring changing social behavior is essential to provide reliable input data for mechanistic models of infectious disease, which have been increasingly used to support public health policy to mitigate the impacts of the pandemic. While some studies have reported on changing contact patterns throughout the pandemic, few have reported differences in contact patterns among key demographic groups and none have reported nationally representative estimates. We conducted a national probability survey of US households and collected information on social contact patterns during two time periods: August-December 2020 (before widespread vaccine availability) and March-April 2021 (during national vaccine rollout). Overall, contact rates in Spring 2021 were similar to those in Fall 2020, with most contacts reported at work. Persons identifying as non-White, non-Black, non-Asian, and non-Hispanic reported high numbers of contacts relative to other racial and ethnic groups. Contact rates were highest in those reporting occupations in retail, hospitality and food service, and transportation. Those testing positive for SARS-CoV-2 antibodies reported a higher number of daily contacts than those who were seronegative. Our findings provide evidence for differences in social behavior among demographic groups, highlighting the profound disparities that have become the hallmark of the COVID-19 pandemic.

Project description:IntroductionCOVID-19 morbidity and mortality has disproportionately affected vulnerable populations such as minority racial/ethnic groups. Understanding disparities in vaccine intentions and reasons for vaccine hesitancy are important for developing effective strategies for ameliorating racial/ethnic COVID-19 inequities.MethodsUsing six waves of the large, nationally representative Census Bureau's Household Pulse Survey data from January 6-March 29, 2021 (n = 459,235), we examined national and state estimates for vaccination intent, defined as receipt of ≥ 1 dose of the COVID-19 vaccine or definite intent to be vaccinated, by race/ethnicity with stratification by household income and age group. In separate logistic regression models, we also examined the interaction between race/ethnicity and household income, and race/ethnicity and age group, and its association with vaccination intent. Lastly, we examined reasons for not vaccinating by race/ethnicity.ResultsVaccination intent differed by racial/ethnic group, household income, and age group nationally and by Health and Human Services (HHS) region and state. A significant interaction was observed between race/ethnicity and household income (F(8,72) = 4.50, p < 0.001), and race/ethnicity and age group (F(8,72) = 15.66, p < 0.001). Non-Hispanic Black adults with lower income (<$35,000) and younger age (18-49 years) were least likely to intend to vaccinate. Similar disparities across racial/ethnic groups were seen across most HHS regions and states. Concerns about possible side effects and effectiveness were significantly higher among all minority groups compared to non-Hispanic White adults.ConclusionDisparities in vaccination intent by racial/ethnic groups underscore the need for interventions and recommendations designed to improve vaccination coverage and confidence in underserved communities, such as younger and lower income racial/ethnic minority groups. Efforts to reduce disparities and barriers to vaccination are needed to achieve equity in vaccination coverage, and ultimately, to curb COVID-19 transmission.

Project description:BackgroundInformation is needed to monitor progress toward a level of population immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sufficient to disrupt viral transmission. We estimated the percentage of the US population with presumed immunity to SARS-CoV-2 due to vaccination, natural infection, or both as of August 26, 2021.MethodsPublicly available data as of August 26, 2021, from the Centers for Disease Control and Prevention were used to calculate presumed population immunity by state. Seroprevalence data were used to estimate the percentage of the population previously infected with SARS-CoV-2, with adjustments for underreporting. Vaccination coverage data for both fully and partially vaccinated persons were used to calculate presumed immunity from vaccination. Finally, we estimated the percentage of the total population in each state with presumed immunity to SARS-CoV-2, with a sensitivity analysis to account for waning immunity, and compared these estimates with a range of population immunity thresholds.ResultsIn our main analysis, which was the most optimistic scenario, presumed population immunity varied among states (43.1% to 70.6%), with 19 states with ≤60% of their population having been infected or vaccinated. Four states had presumed immunity greater than thresholds estimated to be sufficient to disrupt transmission of less infectious variants (67%), and none were greater than the threshold estimated for more infectious variants (≥78%).ConclusionsThe United States remains a distance below the threshold sufficient to disrupt viral transmission, with some states remarkably low. As more infectious variants emerge, it is critical that vaccination efforts intensify across all states and ages for which the vaccines are approved.

Project description:ImportanceFirearm fatality rates in the United States have reached a 28-year high. Describing the evolution of firearm fatality rates across intents, demographics, and geography over time may highlight high-risk groups and inform interventions for firearm injury prevention.ObjectiveTo understand variations in rates of firearm fatalities stratified by intent, demographics, and geography in the US.Design, setting, and participantsThis cross-sectional study analyzed firearm fatalities in the US from 1990 to 2021 using data from the Centers for Disease Control and Prevention. Heat maps, maximum and mean fatality rate graphs, and choropleth maps of county-level rates were created to examine trends in firearm fatality rates by intent over time by age, sex, race, ethnicity, and urbanicity of individuals who died from firearms. Data were analyzed from December 2018 through September 2022.Main outcomes and measuresRates of firearm fatalities by age, sex, race, ethnicity, urbanicity, and county of individuals killed stratified by specific intent (suicide or homicide) per 100 000 persons per year.ResultsThere were a total of 1 110 421 firearm fatalities from 1990 to 2021 (952 984 among males [85.8%] and 157 165 among females [14.2%]; 286 075 among Black non-Hispanic individuals [25.8%], 115 616 among Hispanic individuals [10.4%], and 672 132 among White non-Hispanic individuals [60.5%]). All-intents total firearm fatality rates per 100 000 persons declined to a low of 10.1 fatalities in 2004, then increased to 14.7 fatalities (45.5% increase) by 2021. From 2014 to 2021, male and female firearm homicide rates per 100 000 persons per year increased from 5.9 to 10.9 fatalities (84.7% increase) and 1.1 to 2.0 fatalities (87.0% increase), respectively. Firearm suicide rates were highest among White non-Hispanic men aged 80 to 84 years (up to 46.8 fatalities/100 000 persons in 2021). By 2021, maximum rates of firearm homicide were up to 22.5 times higher among Black non-Hispanic men (up to 141.8 fatalities/100 000 persons aged 20-24 years) and up to 3.6 times higher among Hispanic men (up to 22.8 fatalities/100 000 persons aged 20-24 years) compared with White non-Hispanic men (up to 6.3 fatalities/100 000 persons aged 30-34 years). Males had higher rates of suicide (14.1 fatalities vs 2.0 fatalities per 100 000 persons in 2021) and homicide (10.9 fatalities vs. 2.0 fatalities per 100 000 persons in 2021) compared with females. Metropolitan areas had higher homicide rates than nonmetropolitan areas (6.6 fatalities vs 4.8 fatalities per 100 000 persons in 2021). Firearm fatalities by county level increased over time, spreading from the West to the South. From 1999 to 2011 until 2014 to 2016, fatalities per 100 000 persons per year decreased from 10.6 to 10.5 fatalities in Western states and increased from 12.8 to 13.9 fatalities in Southern states.Conclusions and relevanceThis study found marked disparities in firearm fatality rates by demographic group, which increased over the past decade. These findings suggest that public health approaches to reduce firearm violence should consider underlying demographic and geographic trends and differences by intent.
