A study of 213,445 children in King County, Washington, found that those receiving the MMRV vaccine were more likely to be from safety-net clinics and participate in the Vaccines for Children program.
Background
The combination measles, mumps, rubella, and varicella vaccine (MMRV) is an important option for childhood immunization, yet its uptake may vary significantly across different demographic groups. This study provides insights into the populations that select MMRV.

Key Findings
64% of children received MMR + VAR as their first vaccination.
15% of children received the MMRV vaccine as their first vaccination.
Children receiving MMRV were more likely to be eligible for the Vaccines for Children program.
95% of children completed both measles and varicella vaccine recommendations before age 4.
MMRV use remained stable throughout the study period.
Reduced access to MMRV could disproportionately affect VFC-eligible children.
Clinical Implications
Healthcare providers should be aware of the demographic disparities in vaccine access and consider these factors when planning immunization strategies. Ensuring equitable access to combination vaccines like MMRV is essential for timely vaccination and public health.
Conclusion
The study underscores the importance of understanding vaccine access patterns to inform policy decisions and address potential disparities in immunization among vulnerable populations.
Head and neck abscess incidence was more than 3-fold higher following the pandemic, while patient characteristics and treatment patterns remained largely similar.
