AbstractPurposeTo understand vaccine attitudes of Latinx parents highly impacted by COVID-19. Methods. In April 2021, we surveyed parents about their attitudes for COVID-19 vaccination of their children at a community-based outdoor testing/vaccination site serving predominantly low-income, Latinx persons in San Francisco.ResultsAmong 1,033 parents (75% Latinx), 92% would “definitely” or “probably” vaccinate their children. Vaccine hesitancy was higher for younger children; concerns included side effects and impacts on fertility. Doctors and community organizations were noted as trusted sources of information, including among vaccine-hesitant parents.ConclusionLatinx parents accessing neighborhood-based COVID-19 testing/vaccination services are highly motivated to vaccinate their children for COVID-19.
