“…In 2010-2011, the study recruited FP and pediatric offices; otherwise, the methodology was the same as that employed in previous study years. [10][11][12] Briefly, a sample of US outpatient pediatric and FP offices from the American Medical Association Physicians Masterfile list was recruited through a random selection process. A geographically balanced sample was sought for pediatric and FP offices; however, because of the limited response from FPs, all qualifying FP offices were enrolled.…”

During the 2010-2011 US influenza season, 105 pediatric and 13 family practice offices participated in a prospective observational study of in-office influenza vaccination of children. Office characteristics, influenza vaccinations, and vaccination-related activities were reported. Among pediatric offices, first dose vaccination rates (2% to 60%), 2-dose compliance (11% to 100%), the duration of vaccine availability (60-302 days), and office visit type (well vs sick vs clinic) used for vaccinations varied greatly. Pediatric offices had higher vaccination coverage than family practice offices, offered vaccine longer, and administered more vaccinations during sick visits. Smaller offices and higher staff vaccination rates were associated with higher vaccination coverage. Smaller offices and video reminders in waiting rooms were associated with enhanced 2-dose compliance among children younger than 9 years. A greater understanding of interoffice variability in influenza vaccine delivery by US pediatric providers should allow for the creation of more effective strategies to improve pediatric influenza vaccination rates.

“…7,8 Nonetheless, even among those who initiate vaccination, only 40% to 60% receive a second needed dose. [9][10][11] Timeliness of vaccination is also key, as a child in need of 2 doses is not fully protected until 2 weeks after receipt of the second dose. 8 Even in children who ultimately receive 2 doses in a season, the time interval between doses is often beyond the recommended 28 days.…”

Text Message Reminders for Second Dose of Influenza Vaccine: A Randomized Controlled Trial

et al. 2015

To determine whether provision of vaccine-health-literacy-promoting information in text message vaccine reminders improves receipt and timeliness of the second dose of influenza vaccine within a season for children in need of 2 doses.METHODS: During the 2012-2013 season, families of eligible 6-month through 8-year-old children were recruited at the time of their first influenza vaccination from 3 community clinics in New York City. Children (n = 660) were randomly assigned to "educational" text message, "conventional" text message, and "written reminder-only" arms. At enrollment, all arms received a written reminder with next dose due date. Conventional messages included second dose due date and clinic walk-in hours. Educational messages added information regarding the need for a timely second dose. Receipt of second dose by April 30 was assessed by using x 2 tests. Timeliness was assessed by receipt of second dose by 2 weeks after due date (day 42) using x 2 and over time using a Kaplan-Meier analysis.RESULTS: Most families were Latino and publicly insured with no significant between-arm differences between groups. Children in the educational arm were more likely to receive a second dose by April 30 (72.7%) versus conventional (66.7%) versus written reminder-only arm (57.1%; P = .003). They also had more timely receipt by day 42 (P , .001) and over time (P , .001).CONCLUSIONS: In this low-income, urban, minority population, embedding health literacy information improved the effectiveness of text message reminders in promoting timely delivery of a second dose of influenza vaccine, compared with conventional text messages and written reminder only. WHAT'S KNOWN ON THIS SUBJECT:Influenza vaccine coverage is low, and young children in need of 2 doses in a given season are at particular risk, with less than half receiving both doses. Text message vaccine reminders increase receipt of first dose of influenza vaccine. WHAT THIS STUDY ADDS:Little is known about what types of text message reminders are most effective, including embedding educational information. We demonstrate that text message reminders increase timely receipt of the second dose of influenza vaccine and embedding health literacy information improves effectiveness.

“…Therefore, we limited the analysis to periods when most TIV was administered, between October 1 and January 31 of each influenza season. 12 This resulted in the removal of 3 TIV-exposed children who were vaccinated in the months of February or March. For the matched casecontrol study, we used conditional logistic regression to calculate matched odds ratios and 95% confidence intervals (CIs).…”

Trivalent Inactivated Influenza Vaccine Is Not Associated With Sickle Cell Crises in Children

et al. 2012

View full text Add to dashboard Cite

Background and Objectives: Children with sickle cell disease are considered at high risk for complications from influenza infection and are recommended to receive annual influenza vaccination. However, data on the safety of influenza vaccination in children with sickle cell anemia are sparse. Methods: Using a retrospective cohort of children aged 6 months to 17 years in 8 managed care organizations that comprise the Vaccine Safety Datalink and who had a diagnosis of sickle cell anemia from 1999 to 2006, we conducted matched case-control and self-controlled case series studies to examine the association of trivalent inactivated influenza vaccination with hospitalization for sickle cell crisis in the 2 weeks after vaccination. Results: From an original pool of 1085 pediatric subjects with a diagnosis of sickle cell anemia, we identified 179 children with at least 1 sickle cell crisis during any influenza season (October 1–March 31). In the matched case-control study (matching on age category, gender, Vaccine Safety Datalink site, and season), the odds ratio of hospitalization for a crisis in vaccinated compared with unvaccinated children was not significant: 1.3 (95% confidence interval 0.8–2.2). In the self-controlled case series study of hospitalized cases, the incident rate ratio for hospitalization with sickle cell crisis in the 2 weeks after trivalent inactivated influenza vaccination was also not significant: 1.2 (95% confidence interval 0.75–1.95). Conclusions: This large cohort study did not find an association of influenza vaccination and hospitalization for sickle cell crises in children with sickle cell anemia.
