Objectives. To evaluate the effect of COVID-19 on Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) receipt among pregnant individuals overall and by race/ethnicity.

WHAT IS THE CURRENT KNOWLEDGE ON THE TOPIC? Prior literature utilizing latent class analysis has either focused on attitudes toward a single vaccine (e.g., human papillomavirus [HPV], measles) or questions that are not specific to any vaccine. This body of work has not distinguished between groups whose hesitancy is vaccine-specific or more general; however, it has demonstrated that most hesitant individuals are not “anti-vax.” WHAT QUESTION DID THIS STUDY ADDRESS?
