Factors Influencing COVID-19 Vaccine Uptake among Spanish-Speaking Pregnant People.

The coronavirus disease 2019 (COVID-19) pandemic exposed the vulnerability of pregnant women to excess morbidity and mortality, as well as the disproportionate disease burden in certain racial, ethnic, and sociodemographic groups. Vaccine hesitancy represents a major threat to public health, and crafting messages that reach vulnerable groups and address their intersectionality remains a weakness for pandemic preparedness. We sought to investigate factors that influenced vaccine acceptance and social media ad response in a mixed-methods study of Spanish-speaking women living in the rural Western United States who were pregnant or recently pregnant between November 2022 and June 2023.

COVID-19 Vaccine Hesitancy among English-Speaking Pregnant Women Living in Rural Western United States.

This mixed-method study investigated vaccine hesitancy among pregnant women living in rural western United States and their response to social media ads promoting COVID-19 vaccine uptake. Thirty pregnant or recently pregnant participants who live in rural zip codes in Washington, Oregon, California, and Idaho were interviewed between November 2022 and March 2023. Interviews were transcribed and coded, while the ad ratings were analyzed using linear mixed models.

One Vax Two Lives: a social media campaign and research program to address COVID-19 vaccine hesitancy in pregnancy.

The COVID-19 pandemic has disproportionately affected pregnant people by increasing health risks of maternal morbidity and mortality, stillbirth, and preterm birth. Although numerous studies have supported the safety and efficacy of COVID-19 vaccination in pregnancy in preventing or mitigating the risk for these adverse outcomes, many pregnant people remain hesitant. Approximately half of US adults regularly consume news from social media platforms, which are a fertile ground for the spread of vaccine disinformation.
