Differences in social media use by COVID-19 vaccination status.

The near-ubiquitous use of social media in the United States (U.S.) highlights the utility of social media for encouraging vaccination. Vaccination campaigns have used social media to reach audiences, yet research linking the use of specific social media platforms and vaccination uptake is nascent. This descriptive study assesses differences in social media use by COVID-19 vaccination status among adults overall and those who reported baseline vaccine hesitancy. We used data from a nationally representative longitudinal survey of U.S. adults administered between January 2021-August 2022 (n = 2,908). Results indicated a positive association between frequent Instagram and/or Twitter use and vaccination status (p <.05). Among baseline vaccine hesitant adults, results indicated a positive association between frequent TikTok, Instagram, and/or Twitter use and vaccination status (p <.05). Findings have implications for research that examines the content of social media platforms and their environment on vaccine attitudes and uptake.

Association between vaccination beliefs and COVID-19 vaccine uptake in a longitudinal panel survey of adults in the United States, 2021-2022.

COVID-19 vaccine hesitancy has been a major limiting factor to the widespread uptake of COVID-19 vaccination in the United States. A range of interventions, including mass media campaigns, have been implemented to encourage COVID-19 vaccine confidence and uptake. Such interventions are often guided by theories of behavior change, which posit that behavioral factors, including beliefs, influence behaviors such as vaccination. Although previous studies have examined relationships between vaccination beliefs and COVID-19 vaccination behavior, they come with limitations, such as the use of cross-sectional study designs and, for longitudinal studies, few survey waves. To account for these limitations, we examined associations between vaccination beliefs and COVID-19 vaccine uptake using data from six waves of a nationally representative, longitudinal survey of U.S. adults (N = 3,524) administered over a nearly 2-year period (January 2021-November 2022). Survey-weighted lagged logistic regression models were used to examine the association between lagged reports of vaccination belief change and COVID-19 vaccine uptake, using five belief scales: (1) importance of COVID-19 vaccines, (2) perceived benefits of COVID-19 vaccination, (3) COVID-19 vaccine concerns and risks, (4) normative beliefs about COVID-19 vaccination, and (5) perceptions of general vaccine safety and effectiveness. Analyses controlled for confounding factors and accounted for within-respondent dependence due to repeated measures. In individual models, all vaccination belief scales were significantly associated with increased COVID-19 vaccine uptake. In a combined model, all belief scales except the benefits of COVID-19 vaccination were significant predictors of vaccine uptake. Overall, belief scales indicating the importance of COVID-19 vaccines and normative beliefs about COVID-19 vaccination were the strongest predictors of COVID-19 vaccine uptake. Findings demonstrate that changes in vaccination beliefs influence subsequent COVID-19 vaccine uptake, with implications for the development of future interventions to increase COVID-19 vaccination.

Racial and ethnic differences in COVID-19 vaccine readiness among adults in the United States, January 2021-April 2023.

Racial and ethnic minority groups have been disproportionately affected by COVID-19 and have experienced systemic, attitudinal, and access-related barriers to COVID-19 vaccination. We examined differences in COVID-19 vaccine readiness-a composite measure of vaccination intention and behavior-between non-Hispanic White, non-Hispanic Black, Hispanic, non-Hispanic Asian American/Pacific Islander, and American Indian/Alaska Native U.S. adults. Using data from a cross-sectional survey administered to nationally representative samples of âˆ¼ 5,000 U.S. adults each month from January 2021 to April 2023 (n = 135,989), we conducted weighted ttests comparing the monthly percentage of participants from racial/ethnic groups who were "Vaccine Ready." Initial racial/ethnic disparities in vaccine readiness were attenuated within a 7-month period, after which adults from most minority racial/ethnic groups became equally or more vaccine ready compared to non-Hispanic White adults (p < 0.05). Findings suggest that barriers to vaccine readiness that were more prevalent in non-White racial/ethnic groups may have largely been addressed.
