Objective: In 2015 California passed Senate Bill 227 (SB277), eliminating nonmedical vaccine exemptions for school entry. The objective of this study was to describe the experiences of health officers and immunization staff addressing medical exemption requests under SB277. Methods: We conducted semi-structured telephone interviews between August and September 2017 with health officers and immunization staff from local health jurisdictions in California. Interviews were recorded, transcribed, and analyzed for key themes. Result: We conducted 34 interviews with 40 health officers and immunization staff representing 35 of the 61 local health jurisdictions in California. Four main themes emerged related to experiences with medical exemptions: 1) role of stakeholders, 2) reviewing medical exemptions received by schools, 3) medical exemptions that were perceived as problematic, and 4) frustration and concern over medical exemptions. Generally, local health jurisdictions described a narrow role in providing support and technical assistance to schools. Only five jurisdictions actively tracked medical exemptions received by schools, with one jurisdiction facing a lawsuit as a result. Many examples were provided of medical exemptions that listed conditions that are not consistent with scientifically-justified medical contraindications for immunization (family history of allergies and autoimmune diseases) and of physicians charging steep fees ($150-$300) for medical exemptions. Participants also reported concerns about the burden on schools to review medical exemptions, and about the sharp increase in medical exemptions post-SB277. Conclusion: Participants reported many challenges and concerns with medical exemptions under SB277. Without additional legal changes to SB277, including a standardized review of medical exemptions, some physicians may continue to write medical exemptions for vaccine-hesitant parents, potentially limiting the long-term impact of SB277.

Patients were significantly more likely to report a range of health conditions and motivations associated with medical use than non-patients. A great majority of patients reported obtaining a medical marijuana recommendation for health problems in accordance with the California law.

Understanding how pediatric practices handle parental vaccine hesitancy is important as it impacts the efficiency and effectiveness of pediatric practices. In total, 21 semi-structured interviews with pediatric practice staff within a primary care network were conducted between May 2012 and March 2013. Thematic analysis focused on the barriers and challenges of vaccine hesitancy and strategies to reduce the burden at the practice level. Barriers and challenges of vaccine hesitancy included time constraints, administrative challenges, financial challenges and strained patient-provider relationships. Strategies to minimize the burden of vaccine hesitancy included training for vaccine counseling, screening for vaccine hesitancy prior to immunization visits, tailored vaccine counseling, and primary care provider visits for follow-up immunization. Pediatric practices reported many challenges when caring for vaccine-hesitant families. Multiple strategies were identified to reduce the burden of vaccine hesitancy, which future studies should explore to determine how effective they are in increasing vaccine acceptance in pediatric practices.

Objectives. To understand the experiences of local health jurisdictions with Senate Bill 277 (SB277), the California law that eliminated nonmedical vaccine exemptions for public- and private-school entry. Methods. We conducted semistructured telephone interviews with health officers and local health department (LHD) staff in California between August and September 2017. Results. Two overall themes emerged: (1) vague legislative and regulatory language led to variation in the interpretation and implementation of SB277, and (2) lack of centralized review of medical exemptions allowed medical exemptions that are not consistent with valid contraindications for immunizations to be accepted. Variation in the interpretation and implementation was commonly reported with provisions related to individualized education programs and special education, and independent study programs and homeschooling. Without a centralized review of medical exemption requests, respondents reported variation in the interpretation of which specialties of physicians can write medical exemptions, which conditions constitute a valid contraindication for immunization, and the process for reporting a questionable or suspicious medical exemption. Conclusions. The regulatory language within SB277 led to variation in how the law was interpreted and implemented within and across LHD jurisdictions and school districts.

Background: California's Senate Bill 277 (SB-277) law eliminated the personal belief exemption to school immunization requirements. A potential consequence may be that parents choose homeschooling to avoid immunization.

In March 2017, the Pennsylvania Department of Health reduced the time allowed to demonstrate compliance with school-entry vaccination requirements from eight months to five days. We describe changes in provisional enrollment, vaccine exemptions, and vaccine coverage rates before and after the new regulation. Across Pennsylvania, provisional enrollment decreased from 11.1% in 2016/17 to 2.5% in 2017/18 (77% relative decrease). Personal belief exemptions continued a modest upward trend, similar to previous years, and medical exemptions remained steady. Among kindergartners, coverage with ≥ 2 doses of MMR vaccine and 2 doses of Varicella vaccine increased; similar increases were seen for the MCV and Tdap vaccines among 7th graders. However, improvements in coverage and reductions in provisional enrollment were not consistent across counties. Provisional enrollment in Philadelphia County during the 2017/18 school year (10.4%) did not substantially decrease. The statewide reduction in provisional enrollment suggests that the new regulations accomplished the goal of increasing the proportion of students who are up-to-date on required vaccines at the beginning of the school year without a significant increase in vaccine exemptions. However, the persistence of high provisional enrollment in some counties points to additional barriers to this goal in some schools and regions.

Background Acute otitis media (AOM) is a leading cause of office visits and antibiotic prescriptions in children. Pneumococcal conjugate vaccines were introduced in the USA in 2000 (7-valent, PCV7) and 2010 (13-valent, PCV13). Expanded valency PCVs are currently under development. To describe the impact of PCVs and quantify the residual burden of AOM, this study estimated annual incidence rates (IRs) of AOM and AOM-related complications and surgical procedures in children < 18 years in the USA before and after the introduction of PCV7 and PCV13. Methods AOM episodes were identified in the IBM MarketScan® Commercial and Medicaid databases using diagnosis codes (ICD-9-CM: 382.x; ICD-10-CM: H66.xx and H67.xx). Annual IRs were calculated as the number of episodes per 1000 person-years (PYs) for all children < 18 years and by age group (< 2, 2–4, and 5–17 years). National estimates of annual AOM IRs were extrapolated using Census Bureau data. Interrupted time series analyses were used to assess immediate and gradual changes in monthly AOM IRs, controlling for seasonality. Results In the commercially insured population, AOM IRs declined between the pre-PCV7 period (1998–1999) and the late PCV13 period (2014–2018) from 1170.1 to 768.8 episodes per 1000 PY for children < 2 years, from 547.4 to 410.3 episodes per 1000 PY in children 2–4 years, and from 115.6 to 91.8 episodes per 1000 PY in children 5–17 years. The interrupted time series analyses indicated significant immediate or gradual decreases in the early PCV7 period (2001–2005), and gradual increases in the late PCV7 period (2006–2009) in children < 2 years; however, crude IRs trended downward in all time periods. In older children, IRs decreased in the early PCV7 and early PCV13 period (2011–2013), but gradually increased in the late PCV7 period. IRs of AOM-related surgical procedures decreased, and IRs of AOM-related complications increased during the study timeframe. Conclusions AOM disease burden remains high in children of all ages despite overall reductions in AOM IRs during 1998–2018 following the introduction of PCV7 and PCV13. The impact of investigational PCVs on the disease burden of AOM will likely depend on AOM etiology and circulating pneumococcal serotypes.
