RESUMO
Around 142 million American adults are currently single; at least half of these singles want to pursue a romantic partner. Romantic dating can involve exposure to numerous people. Thus, dating can significantly impact pathogen exposure risk. In a demographically-representative cross-sectional survey conducted in 2021 (N = 5,000), we examined U.S. American singles' COVID-19 vaccination status, assessed their preferences around a potential partner's COVID-19 vaccination status, and identified demographic subgroups of singles particularly opposed to or indifferent to a partner being vaccinated against COVID-19. Our results showed 65% of participants were fully vaccinated, 10% were partially vaccinated, and 26% were unvaccinated against COVID-19. With regards to partner preferences, half wanted a vaccinated partner; 18.9% wanted a vaccinated partner but would make exceptions; 6.1% wanted an unvaccinated partner; and 25% reported that they did not care about their dating partner's vaccination status. Partner preferences were largely aligned with participants' own vaccination status, such that vaccinated participants preferred vaccinated partners. However, those preferring unvaccinated partners-or those willing to make exceptions for a partner-were most likely to identify as men, younger in age, a political affiliation outside of the two-party political system, a gender or sexual minority, or as a racial minority (i.e., Black/African-American or South Asian). Additionally, participants who were employed (vs. unemployed) were more likely to make exceptions for or prefer an unvaccinated partner. These results suggest that singles prefer homophily in COVID-19 vaccine status, and that minoritized subgroups of singles are more likely to maintain a social network including unvaccinated close others.
