Abstract
BACKGROUND An mRNA-based RSV vaccine, mRNA-1345, is under clinical investigation to address RSV disease burden in older adults. METHODS This phase 1, randomized, observer-blind, placebo-controlled, dose-ranging study evaluated safety, reactogenicity, and immunogenicity of mRNA-1345 in adults 65-79 years (NCT04528719). Participants were randomized to receive 1-dose of mRNA-1345 (12.5, 25, 50, 100, or 200-µg) or placebo and matched mRNA-1345 booster or placebo at 12-months. RESULTS Overall, 298 participants received the first injection; 247 received the 12-month booster injection. mRNA-1345 was generally well-tolerated after both injections, with the most frequently reported solicited adverse reactions being injection-site pain, fatigue, headache, arthralgia, and myalgia. Reactogenicity was higher after the booster injection than the first injection but similar severity, time-to-onset, and duration. A single mRNA-1345 injection boosted RSV-A and RSV-B neutralizing antibody titers (nAb) and prefusion-F-binding antibody (preF-bAb) concentrations at 1-month (geometric mean-fold rises: RSV-A, 10.2-16.5; RSV-B, 5.3-12.5; preF-bAb, 7.2-12.1). RSV antibody levels remained above baseline through 12-months, indicating immune persistence. A 12-month booster injection also increased RSV-A and RSV-B nAb titers and preF-bAb concentrations; titers post-booster injection were numerically lower compared to titers after the first-dose, with overlapping 95% CIs. CONCLUSIONS mRNA-1345 was well-tolerated and immunogenic following a single injection and a 12-month booster. TRIAL REGISTRATION ClinicalTrials.gov, NCT04528719.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) can cause substantial morbidity and mortality among older adults. An mRNA-based RSV vaccine, mRNA-1345, encoding the stabilized RSV prefusion F glycoprotein, is under clinical investigation. METHODS In this ongoing, randomized, double-blind, placebo-controlled, phase 2-3 trial, we randomly assigned, in a 1:1 ratio, adults 60 years of age or older to receive one dose of mRNA-1345 (50 μg) or placebo. The two primary efficacy end points were the prevention of RSV-associated lower respiratory tract disease with at least two signs or symptoms and with at least three signs or symptoms. A key secondary efficacy end point was the prevention of RSV-associated acute respiratory disease. Safety was also assessed. RESULTS Overall, 35,541 participants were assigned to receive the mRNA-1345 vaccine (17,793 participants) or placebo (17,748). The median follow-up was 112 days (range, 1 to 379). The primary analyses were conducted when at least 50% of the anticipated cases of RSV-associated lower respiratory tract disease had occurred. Vaccine efficacy was 83.7% (95.88% confidence interval [CI], 66.0 to 92.2) against RSV-associated lower respiratory tract disease with at least two signs or symptoms and 82.4% (96.36% CI, 34.8 to 95.3) against the disease with at least three signs or symptoms. Vaccine efficacy was 68.4% (95% CI, 50.9 to 79.7) against RSV-associated acute respiratory disease. Protection was observed against both RSV subtypes (A and B) and was generally consistent across subgroups defined according to age and coexisting conditions. Participants in the mRNA-1345 group had a higher incidence than those in the placebo group of solicited local adverse reactions (58.7% vs. 16.2%) and of systemic adverse reactions (47.7% vs. 32.9%); most reactions were mild to moderate in severity and were transient. Serious adverse events occurred in 2.8% of the participants in each trial group. CONCLUSIONS A single dose of the mRNA-1345 vaccine resulted in no evident safety concerns and led to a lower incidence of RSV-associated lower respiratory tract disease and of RSV-associated acute respiratory disease than placebo among adults 60 years of age or older.

Abstract
HPV vaccination rates remain suboptimal in the United States. While the current literature focuses on expressly hesitant parents, few studies have examined parents with "high intent", or those indicating they definitely will vaccinate and have had the opportunity but not yet vaccinated their adolescents. Our objective was to differentiate characteristics of mothers with high intent from those who already vaccinated their adolescents using various socioeconomic, previous vaccine decision-making, and healthcare provider relationship-related variables. English-speaking mothers or female guardians of adolescents ages 11-14 years living in low HPV vaccine uptake states within the U.S. in September 2018 were recruited from a national survey panel as part of a larger study. We assessed HPV vaccine status of their adolescents and categorized respondents into two categories: Already Vaccinated and High Intent. We assessed differences using a multivariable logistic regression model. Among 2406 mothers, 18% reported high intent vs. 82% already having vaccinated. Mothers with high intent were more likely to identify as non-Hispanic White (p = 0.01), to have a younger adolescent (p < 0.001), and to report not receiving a provider HPV vaccination recommendation (p < 0.001). Mothers who estimated that half/more (vs. less) of their child's friends have received/will receive the vaccine had higher odds of already vaccinating (p < 0.001). Our findings suggest that clinicians may be able to improve HPV vaccination uptake within their practices by giving repeated, high-quality recommendations to parents of children who are not yet vaccinated. Additionally, these findings indicate perceived social norms may play a large role in on-time vaccine uptake. Reassuring hesitant parents that most parents accept the vaccine may also improve uptake in clinical practice.

Abstract
Background Respiratory syncytial virus (RSV) is a public health burden; no vaccine is currently available. An mRNA-based RSV vaccine (mRNA-1345) encoding the RSV prefusion stabilized F (preF) glycoprotein is under clinical investigation. Methods A phase 1, randomized, observer-blind, placebo-controlled, dose-ranging study assessed safety and immunogenicity of mRNA-1345 in younger adults (YA; 18-49 years) and older adults (OA; 65-79 years) (NCT04528719). YA and OA were randomized to receive 1 dose of mRNA-1345 (50, 100, or 200 µg) or placebo. Results In all, 74 YA participants (mRNA-1345, n=19-20; placebo, n=15) and 202 OA participants (mRNA-1345, n=47-48; placebo, n=59) received study injections. mRNA-1345 was well-tolerated in both groups, with lower reactogenicity observed in OA vs YA at higher doses. Injection site pain was the most frequent local solicited adverse reaction (SAR, YA: mRNA-1345, 73.7-100%; placebo, 0%; OA: mRNA-1345, 61.7-78.7%; placebo, 12.7% [Fig 1]). Erythema and swelling were less frequent (mRNA-1345: YA, 5.3-15.0%; OA, 0-4.3%; and YA, 5.0-15.0%; OA, 2.1-4.3%; respectively vs placebo 0% for all). Overall, 57.9-100% (YA) and 53.2-78.7% (OA) of mRNA-1345 and 40.0% (YA) and 45.5% (OA) of placebo groups reported ≥ 1 systemic SAR, most commonly headache, fatigue, myalgia, and arthralgia. As expected, neutralizing antibodies (nAbs) were present at baseline (BL; Fig 2); mRNA-1345 significantly boosted antibody titers through month (M) 1 in YA and OA, with comparable immunogenicity observed across age groups. M1 geometric mean fold rise (GMFR) for RSV-A nAbs were 20.0-22.3 (YA) and 12.1-16.6 (OA) and for RSV-B, nAbs were 11.7-14.4 (YA) and 8.7-12.6 (OA). M1 PreF binding antibody (bAb) GMFRs were 16.1-21.7 (YA) and 8.4-12.1 (OA; Fig 3). Peak antibody titers declined through M6, but levels remained ≥ 4.1-fold above BL with minimal dose response. M6 GMFR for RSV-A nAbs were 7.0-9.6 (YA) and 4.1-5.8 (OA) and for RSV-B, nAbs were 5.0-8.9 (YA) and 4.5-5.5 (OA). M6 PreF bAbs GMFR were 5.9-7.0 (YA) and 4.1-4.7 (OA). Antibody decline over time was comparable in YA and OA cohorts.
![]() ![]() ![]() Conclusion mRNA-1345 is well-tolerated in YA and OA. Antibody levels were boosted substantially above BL through M6 in both cohorts. These data support the continued development of mRNA-1345 as an RSV vaccine. Disclosures Grace L.

Abstract
Abstract
Background
RSV causes acute respiratory disease (ARD), including severe lower respiratory tract disease (LRTD) in older adults, which can lead to hospitalization and death. Currently, there are no vaccines approved to prevent RSV disease. This study estimated the potential clinical impact of a hypothetical RSV vaccine over a 1-year time horizon in older adults aged ≥ 60 years.
Methods
A decision-analytic model was developed (Figure 1). A strategy was used where the entire US population aged ≥ 60 years was given a single dose vaccine with an assumed efficacy of 75% against ARD, LRTD, and LRTD-hospitalizations and compared to a population who did not receive a vaccine. Given the uncertainty around RSV hospitalization rates, 2 base-case scenarios were created: (1) hospitalization rates that used RSV-specific claim codes and (2) hospitalization rates increased by 49% to account for underreporting in claims; Table 1 shows key inputs. One-way sensitivity analyses were used to assess the impact of specific parameter estimates.
Results
The vaccine would prevent 1.8 million and 0.6 million upper respiratory disease and LRTD cases, respectively; Figure 2 shows additional results for both base-case scenarios. The number needed to vaccinate (NNV) to prevent 1 LRTD case is 119; the NNV to prevent 1 LRTD hospitalization or death ranges from 792 to 1180 and 10,452 to 15,574, respectively. Sensitivity analyses indicate that results mainly depend on vaccine efficacy, and incidence of ARD and LRTD.
Conclusion
There is substantial US public health benefit associated with utilization of an effective RSV vaccine in individuals ≥ 60 years of age to reduce RSV-associated morbidity and mortality; however, the magnitude of impact depends on RSV epidemiology, which is still being defined for older adults. Several model parameters were based on assumptions, and robust evidence generation is needed including the efficacy of an RSV vaccine, which is an important consideration in assessing the impact of vaccination in this age group.

Abstract
BACKGROUND Chemotherapy-induced febrile neutropenia (FN) is prevented or minimized with granulocyte colony-stimulating factors (G-CSFs). Several G-CSF biosimilars are approved in the United States. The Biologics and Biosimilars Collective Intelligence Consortium (BBCIC) is a nonprofit initiative whose objective is to provide scientific evidence on real-world use and comparative safety and effectiveness of biologics and biosimilars using the BBCIC distributed research network (DRN). PATIENTS AND METHODS We describe real-world G-CSF use in patients with breast or lung cancer receiving first-cycle chemotherapy associated with high FN risk. We assessed hospitalizations for FN, availability of absolute neutrophil counts, and G-CSF-induced adverse events to inform future observational comparative effectiveness studies of G-CSF reference products and their biosimilars. A descriptive analysis of 5 participating national health insurance plans was conducted within the BBCIC DRN. RESULTS A total of 57,725 patients who received at least one G-CSF dose were included. Most (92.5%) patients received pegfilgrastim. FN hospitalization rates were evaluated by narrow (<0.5%), intermediate (1.91%), and broad (2.99%) definitions. Anaphylaxis and hyperleukocytosis were identified in 1.15% and 2.28% of patients, respectively. This analysis provides real-world evidence extracted from a large, readily available database of diverse patients, characterizing G-CSF reference product use to inform the feasibility of future observational comparative safety and effectiveness analyses of G-CSF biosimilars. We showed that the rates of FN and adverse events in our research network are consistent with those reported by previous small studies. CONCLUSIONS Readily available BBCIC DRN data can be used to assess G-CSF use with the incidence of FN hospitalizations. Insufficient laboratory result data were available to report absolute neutrophil counts; however, other safety data are available for assessment that provide valuable baseline data regarding the effectiveness and safety of G-CSFs in preparation for comparative effectiveness studies of reference G-CSFs and their biosimilars.

Abstract
BACKGROUND Identifying pregnancy episodes and accurately estimating their beginning and end dates are imperative for observational maternal vaccine safety studies using electronic health record (EHR) data. METHODS We modified the Vaccine Safety Datalink (VSD) Pregnancy Episode Algorithm (PEA) to include both the International Classification of Disease, ninth revision (ICD-9 system) and ICD-10 diagnosis codes, incorporated additional gestational age data, and validated this enhanced algorithm with manual medical record review. We also developed the new Dynamic Pregnancy Algorithm (DPA) to identify pregnancy episodes in real time. RESULTS Around 75% of the pregnancy episodes identified by the enhanced VSD PEA were live births, 12% were spontaneous abortions (SABs), 10% were induced abortions (IABs), and 0.4% were stillbirths (SBs). Gestational age was identified for 99% of live births, 89% of SBs, 69% of SABs, and 42% of IABs. Agreement between the PEA-assigned and abstractor-identified pregnancy outcome and outcome date was 100% for live births, but was lower for pregnancy losses. When gestational age was available in the medical record, the agreement was higher for live births (97%), but lower for pregnancy losses (75%). The DPA demonstrated strong concordance with the PEA and identified pregnancy episodes ⩾6 months prior to the outcome date for 89% of live births. CONCLUSION The enhanced VSD PEA is a useful tool for identifying pregnancy episodes in EHR databases. The DPA improves the timeliness of pregnancy identification and can be used for near real-time maternal vaccine safety studies. PLAIN LANGUAGE SUMMARY Improving identification of pregnancies in the Vaccine Safety Datalink electronic medical record databases to allow for better and faster monitoring of vaccination safety during pregnancy Introduction: It is important to monitor of the safety of vaccines after they have been approved and licensed by the Food and Drug Administration, especially among women vaccinated during pregnancy. The Vaccine Safety Datalink (VSD) monitors vaccine safety through observational studies within large databases of electronic medical records. Since 2012, VSD researchers have used an algorithm called the Pregnancy Episode Algorithm (PEA) to identify the medical records of women who have been pregnant. Researchers then use these medical records to study whether receiving a particular vaccine is linked to any negative outcomes for the woman or her child.Methods: The goal of this study was to update and enhance the PEA to include the full set of medical record diagnostic codes [both from the older International Classification of Disease, ninth revision (ICD-9 system) and the newer ICD-10 system] and to incorporate additional sources of data about gestational age. To ensure the validity of the PEA following these enhancements, we manually reviewed medical records and compared the results with the algorithm. We also developed a new algorithm, the Dynamic Pregnancy Algorithm (DPA), to identify women earlier in pregnancy, allowing us to conduct more timely vaccine safety assessments.Results: The new version of the PEA identified 2,485,410 pregnancies in the VSD database. The enhanced algorithm more precisely estimated the beginning of pregnancies, especially those that did not result in live births, due to the new sources of gestational age data.Conclusion: Our new algorithm, the DPA, was successful at identifying pregnancies earlier in gestation than the PEA. The enhanced PEA and the new DPA will allow us to better evaluate the safety of current and future vaccinations administered during or around the time of pregnancy.

Abstract
The efficacy of a tailored video intervention differed by sociodemographics. Further research should evaluate interventions tailored by sociodemographics. Tailoring interventions by child age and other factors may improve efficacy.
We assessed differences in response to a tailored recommendation intervention for HPV vaccine by participants’ sociodemographic characteristics in this exploratory sub-analysis of a larger web-based, randomized-controlled trial on tailored messaging among mothers with low intent to vaccinate their 11–14-year-old child against HPV. The intervention consisted of pre-recorded video messages tailored to 1–5 common concerns about HPV vaccine. In these exploratory analyses, we used generalized linear models to assess differences in post-intervention intent across intervention arms, stratified by sociodemographic characteristics among 496 trial participants. We found significantly higher post-intervention intent in the intervention participants versus the control group among mothers: 1) with younger children; 2) with white vs. black children; 3) with Non-Hispanic children; 4) who were younger; 5) with some college or vocational training; with household incomes of ≥$100,000; and 7) with 1–2 children. Our findings of effect modification by certain sociodemographic factors such as age, race/ethnicity, and household income should be considered when designing similar tailored messaging interventions.

Abstract
Background and purpose The transition from International Classification of Diseases, 9th revision, clinical modification (ICD‐9‐CM) to ICD‐10‐CM poses a challenge to epidemiologic studies that use diagnostic codes to identify health outcomes and covariates. We evaluated coding trends in health outcomes in the US Food and Drug Administration's Sentinel System during the transition. Methods We reviewed all health outcomes coding trends reports on the Sentinel website through November 30, 2019 and analyzed trends in incidence and prevalence across the ICD‐9‐CM and ICD‐10‐CM eras by visual inspection. Results We identified 78 unique health outcomes (22 acute, 32 chronic, and 24 acute or chronic) and 140 time‐series graphs of incidence and prevalence. The reports also included code lists and code mapping methods used. Of the 140 graphs reviewed, 81 (57.9%) showed consistent trends across the ICD‐9‐CM and ICD‐10‐CM eras, while 51 (36.4%) and 8 (5.7%) graphs showed inconsistent and uncertain trends, respectively. Chronic HOIs and acute/chronic HOIs had higher proportions of consistent trends in prevalence definitions (83.9% and 78.3%, respectively) than acute HOIs (28.6%). For incidence, 55.6% of acute HOIs showed consistent trends, while 41.2% of chronic HOIs and 39.3% of acute/chronic HOIs showed consistency. Conclusions Researchers using ICD‐10‐CM algorithms obtained by standardized mappings from ICD‐9‐CM algorithms should assess the mapping performance before use. The Sentinel reports provide a valuable resource for researchers who need to develop and assess mapping strategies. The reports could benefit from additional information about the algorithm selection process and additional details on monthly incidence and prevalence rates. Key points We reviewed health outcomes coding trends reports on the US FDA Sentinel website through November 30, 2019 and analyzed trends in incidence and prevalence across the International Classification of Diseases, 9th revision, Clinical Modification (ICD‐9‐CM) and ICD‐10‐CM eras by code mapping method and the type of health outcomes of interest (acute, chronic, acute or chronic). More than a third of the 140 time‐series graphs of incidence and prevalence of health outcomes showed inconsistent or uncertain trends. Consistency in trends varied by code mapping method, type of health outcomes of interest, and whether the measurement was incidence or prevalence. Studies using ICD‐9‐CM‐based algorithms mapped to ICD‐10‐CM codes need to assess the performance of the mappings and conduct manual refinement of the algorithms as needed before using them.

Abstract
PURPOSE Given the 2015 transition to International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnostic coding, updates to our previously published algorithms for major structural birth defects (BDs) were necessary. Aims of this study were to update, validate, and refine algorithms for identifying selected BDs, and then to use these algorithms to describe BD prevalence in the vaccine safety datalink (VSD) population. METHODS We converted our ICD-9-CM list of selected BDs to ICD-10-CM using available crosswalks with manual review of codes. We identified, chart reviewed, and adjudicated a sample of infants in the VSD with ≥2 ICD-10-CM diagnoses for one of seven common BDs. Positive predictive values (PPVs) were calculated; for BDs with suboptimal PPV, algorithms were refined. Final automated algorithms were applied to a cohort of live births delivered 10/1/2015-9/30/2017 at eight VSD sites to estimate BD prevalence. This research was approved by the HealthPartners Institutional Review Board, by all participating VSD sites, and by the CDC, with a waiver of informed consent. RESULTS Of 573 infants with ≥2 diagnoses for a targeted BD, on adjudication, we classified 399 (69.6%) as probable cases, 31 (5.4%) as possible cases and 143 (25.0%) as not having the targeted BD. PPVs for the final BD algorithms ranged from 0.76 (hypospadias) to 1.0 (gastroschisis). Among 212 857 births over 2 years following transition to ICD-10-CM coding, prevalence for the full list of selected defects in the VSD was 1.8%. CONCLUSIONS Algorithms can identify infants with selected BDs using automated healthcare data with reasonable accuracy. Our updated algorithms can be used in observational studies of maternal vaccine safety and may be adapted for use in other surveillance systems.

Abstract
There is large county-level geographic variation in pneumonia and influenza hospitalizations among short-stay and long-stay long-term care facility residents in the United States. Long-term care facilities in counties in the Southern and Midwestern regions had the highest rates of pneumonia and influenza from 2013 to 2015. Future research should identify reasons for these geographic differences.

Abstract
OBJECTIVE To estimate real-world off-label use of sodium-glucose cotransporter 2 (SGLT2) inhibitors in patients with type 1 diabetes, estimate rates of diabetic ketoacidosis (DKA), and compare them with DKA rates observed in sotagliflozin clinical trials. RESEARCH DESIGN AND METHODS We identified initiators of SGLT2 inhibitors in the Sentinel System from March 2013 to June 2018, determined the prevalence of type 1 diabetes using a narrow and a broad definition, and measured rates of DKA using administrative claims data. Standardized incidence ratios (SIRs) were calculated using age- and sex-specific follow-up time in Sentinel and age- and sex-specific DKA rates from sotagliflozin trials 309, 310, and 312. RESULTS Among 475,527 initiators of SGLT2 inhibitors, 0.50% and 0.92% met narrow and broad criteria for type 1 diabetes, respectively. Rates of DKA in the narrow and broad groups were 7.3/100 person-years and 4.5/100 person-years, respectively. Among patients who met narrow criteria for type 1 diabetes, rates of DKA were highest for patients aged 25-44 years, especially females aged 25-44 years (19.7/100 person-years). More DKA events were observed during off-label use of SGLT2 inhibitors in Sentinel than would be expected based on sotagliflozin clinical trials (SIR = 1.83; 95% CI 1.45-2.28). CONCLUSIONS Real-world off-label use of SGLT2 inhibitors among patients with type 1 diabetes accounted for a small proportion of overall SGLT2 inhibitor use. However, the risk for DKA during off-label use was notable, especially among young, female patients. Although real-word rates of DKA exceeded the expectation based on clinical trials, results should be interpreted with caution due to differences in study methods, patient samples, and study drugs.

Abstract
Background Data from randomized controlled trials and observational studies on older adults who take statins for primary prevention of atherosclerotic cardiovascular disease are limited. To determine the incidence of statin use in older adults with and without cardiovascular disease (CVD) and/or diabetes (DM), we conducted a descriptive observational study. Methods The cohort consisted of health plan members in the NIH Collaboratory Distributed Research Network aged >75 years who had continuous drug and medical benefits for ≥183 days during the study period, January 1, 2008- March 31, 2018. We defined DM and CVD using diagnosis codes, and identified statins using dispensing data. Statin use was considered incident if a member had no evidence of statin exposure in the claims during the previous 183 days, and the use was considered long-term if statins were supplied for ≥180 days. Incidence rates were reported among members with and without CVD and/or diabetes, and stratified by year, sex, and age group. Results Among 757,569 eligible members, 109,306 older adults initiated statins and 54,624 became long-term users. Health plan members with CVD had the highest incidence of statin use (143.9 initiators per 1,000 member-years for CVD & DM; 114.5 initiators per 1,000 member-years for CVD & No DM). Among health plan members without CVD, those with DM had rates of statin use that were over two times higher than members without DM (76.1 versus 34.5 initiators per 1,000 member-years, respectively). Statin initiation remained steady throughout 2008–2016, was slightly higher in males, and declined with increasing age. Conclusion Incidence of statin use varied by CVD and DM comorbidity, and was lowest among those without CVD. These results highlight the potential clinical equipoise to conduct large pragmatic clinical trials to generate evidence that could be used to inform future blood cholesterol guidelines.

Abstract
BACKGROUND As new biosimilar and follow-on insulins enter the market, more data are needed on safety, effectiveness, and patterns of use for these products to inform prescriber and patient decision-making regarding treatment. Additionally, data are needed regarding real-world patterns of use to inform future studies comparing the safety and effectiveness of bio-similars to already approved agents for diabetes treatment. OBJECTIVE To analyze the medication use patterns, adverse events, and availability of glycated hemoglobin (A1c) values for adult patients with type 2 diabetes mellitus (T2DM) who use long-acting insulin (LAI) or neutral protamine Hagedorn (NPH), an intermediate-acting insulin. METHODS We used the Biologics and Biosimilars Collective Intelligence Consortium's (BBCIC) distributed research network (DRN) for this descriptive analysis. The analysis time frame was January 1, 2011, to September 30, 2015, and included patients continuously insured for at least 183 days before the first date of a filled prescription for LAI or NPH insulin alone or with rapid- or short-acting insulin or sulfonylureas, whether newly starting insulin or switching to a different product. Insulin exposure episodes were the unit of analysis, and patients were classified in cohorts according to treatment. We followed patients until end of health plan enrollment or the end of the study period. We used occurrence of a study outcome, switch to another medication regimen, discontinuation of the current medication, or study end date to mark the end of an insulin episode. We describe demographics and availability of A1c values for analysis. Study outcomes included severe hypoglycemic events and major adverse cardiac events (MACE). RESULTS We identified 103,951 patients with T2DM from a database of 39.1 million patients with commercial or Medicare Advantage pharmacy and medical benefits, who contributed 279,533 unique insulin exposure episodes. Most episodes (89%) included patients using LAI, and 52% of patients contributed data to 2 or more exposure cohorts. Insulin episodes lasted an average of 3.5 months, and patients had an average follow-up of 8.6 months. The unadjusted rate of severe hypoglycemic events requiring medical attention was 96.9 per 10,000 patient-years at risk (10kPYR). The unadjusted incident MACE rate was 676.9 events per 10kPYR. 38,330 T2DM patients in the BBCIC DRN had a baseline A1c available, and of those, less than 50% had a follow-up A1c result. CONCLUSIONS Among patients with T2DM, our observed insulin patterns of use and rates of severe hypoglycemic outcomes and MACE are consistent with other studies. We noted a paucity of A1c results available, which implies that additional data sources may be needed to augment the BBCIC DRN.

Abstract
INTRODUCTION As clinical trials test efficacy rather than effectiveness of medications, real-world effectiveness data often vary from clinical trial data. Given the recent market entry of multiple biologics and biosimilars, a dedicated assessment of these diverse agents is needed to build the evidence base regarding efficacy and safety of innovator biologics and biosimilars. PROGRAM DESCRIPTION The Academy of Managed Care Pharmacy's Biologics and Biosimilars Collective Intelligence Consortium (BBCIC) was convened to address the lack of real-world, postmarket outcome evidence generation for innovator biologics and corresponding biosimilars. The BBCIC is a multistakeholder scientific research consortium whose participants prioritize topics and collaboratively conduct research studies. The BBCIC conducts a wide range of analyses, including population characterization, epidemiologic studies, and active observational studies, and develops best practices for conducting large-scale studies to provide real-world evidence. OBSERVATIONS Over the past 3 years, we undertook multiple descriptive analyses with the goal of characterizing data availability and demonstrating the feasibility and efficacy of using the BBCIC distributed research network (DRN), which includes commercial claims data from 2008-2018 covering approximately 100 million lives, with approximately 20 million active members in 2017 from 2 major U.S. health plans and 3 regional integrated delivery networks. We analyzed 4 medication classes of particular interest to biologics and biosimilars development: insulins, granulocyte colony-stimulating factors, erythropoietic-stimulating agents, and anti-inflammatories. We were able to identify exposures and user characteristics in all 4 categories. Herein we describe the successes and challenges of conducting some of our analyses, specifically among insulin users with type 1 diabetes mellitus. IMPLICATIONS Our results demonstrate the BBCIC DRN's ability to identify and characterize exposures, cohorts, and outcomes that can contribute to more sophisticated comparative surveillance of biosimilars and innovator biologics in the future. Additional linkages to laboratory data and a wider range of insurance carriers will further strengthen the BBCIC DRN.

Abstract
The human papillomavirus (HPV) vaccine has been available in the United States for over a decade. We sought to examine the associations between self-reported receipt of HPV vaccination among women and their 11-14-year-old children in 27 low-coverage states. Among the 3,261 mothers we surveyed, 18% reported receiving ≥1 dose of HPV vaccine. A significantly higher proportion of vaccinated women reported vaccination of their children compared to unvaccinated women (83% vs. 56%, p < .001). In multivariable logistic regression, vaccinated women (vs. unvaccinated) had 3.58 (95% CI: 2.81-4.56) times the adjusted-odds of vaccinating their children (≥1 dose HPV vaccine). Among unvaccinated children, vaccinated mothers (vs. unvaccinated) had 3.32 (95% CI: 2.09-5.26) times the adjusted odds of high intention to vaccinate their children in the next 12 months. We did not observe associations between mothers' vaccination confidence and their vaccination status. We conclude that mothers who received ≥1 dose of HPV vaccine may be more likely to initiate or highly intend to initiate the HPV vaccine series for their children. This may have important implications for meeting population goals for HPV vaccination coverage as an increasing proportion of mothers are likely to be vaccinated over time.

Abstract
Differences in state Medicaid policies and practices may result in variation in the recording of individual-level vaccination claims, which may present challenges for vaccination research using state Medicaid data. We describe differences in procedure coding for rotavirus vaccination in four states' Medicaid programs by identifying rotavirus vaccine-specific codes and oral vaccine administration codes. The proportion of vaccinated children with vaccine-specific and oral vaccine administration codes differed substantially across states: two states used vaccine-specific codes almost exclusively (95.9% and 99.0%); one had exclusively oral vaccine administration codes (>99.9%); another had a mixture (32.1% vaccine-specific codes, 40.0% oral vaccine administration codes, and 27.9% both). Depending on the research question, studies using Medicaid data in states without (or with incomplete) vaccine-specific coding may be infeasible. Prior to initiating research, investigators should carefully evaluate state Medicaid policies and patterns of vaccination uptake, as vaccine reimbursement policies and availability of vaccine claims may vary.

Abstract
Background. Health insurers are well-positioned to address low HPV vaccination coverage in the US through initiatives such as provider assessment and feedback. However, little is known about the feasibility of using administrative claims data to assess provider performance on vaccine delivery. Methods. We used administrative claims data from a regional health plan to estimate provider performance on the 2013-2015 Healthcare Effectiveness Data and Information Set (HEDIS) measure for HPV vaccine. This measure required that a girl receive three doses of HPV vaccine by age 13. Providers who administered ≥1 dose in a HEDIS-consistent series received credit for meeting the goal. Results. From January 2008-April 2015, 1,975 (8.5%) of 11-12 year-old girls in our sample received a HEDIS-consistent HPV vaccine series. Our sample of providers consisted of 1,236 who had ≥10 well-visits with different female patients, and 94% of these were pediatricians. A substantial minority of providers (39.4%) did not administer any HEDIS-consistent HPV vaccine doses. Only 5.5% of providers administered HPV vaccine doses that were part of a HEDIS-consistent series to at least one-quarter of their patients. These estimates did not vary by provider sex or age. Doses in a HEDIS-consistent vaccine series were often attributed to multiple providers. Conclusions. In a regional health plan, only 5.5% of providers in our sample administered doses that were part of a complete, three-dose HPV vaccine series to at least one-quarter of their 11-12 year-old female patients.

Abstract
BACKGROUND The aim of this study was to evaluate the short-term risk of adverse events associated with rotavirus vaccine (RV) in infants, overall and by vaccine formulation (three-dose pentavalent, RV5; two-dose monovalent, RV1). METHODS We identified US newborns with commercial insurance during 2006-2014 receiving a diphtheria-tetanus-pertussis vaccine (DTaP) dose and assessed if RV was administered concurrently. We followed infants for 30 days after each dose for diagnoses of intussusception, other gastrointestinal events, seizures, Kawasaki disease, thrombocytopenia, otitis media, all-cause emergency department visits, and all-cause hospitalisations. We estimated adjusted hazard ratios (HR) and 95% confidence intervals (CI) with multivariable Cox proportional hazards models comparing: (a) those receiving DTaP+RV vs those receiving DTaP alone; and (b) RV5 vs RV1. Analyses were performed separately within DTaP doses and then meta-analysed across doses. RESULTS We identified 1 031 431 first DTaP doses, 821 833 second doses, and 615 293 third doses; 79.2% had a concurrent RV, 94.1% of which were RV5. Absolute risks of serious outcomes were very low. Compared to infants who received DTaP alone, infants who received RV+DTaP did not experience consistently increased risk of intussusception (hazard ratio [HR] 1.13, 95% confidence interval [CI] 0.68, 1.88) or any other outcome except for otitis media after dose 2: HR 1.11, 95% CI 1.08, 1.15. This increased otitis media risk was not as pronounced in RV5 when comparing RV5 to RV1; HR 0.92, 95% CI 0.89, 0.95. CONCLUSIONS These data were not consistent with an increased risk of intussusception or other adverse events following vaccination with RV, except potentially for a small increased risk of otitis media, particularly in RV1.

Abstract
PURPOSE To replicate the well-established association between angiotensin-converting enzyme inhibitors versus beta blockers and angioedema in the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) era. METHODS We conducted a retrospective, inception cohort study in a large insurance database formatted to the Sentinel Common Data Model. We defined study periods spanning the ICD-9-CM era only, ICD-10-CM era only, and ICD-9-CM and ICD-10-CM era and conducted simple-forward mapping (SFM), simple-backward mapping (SBM), and forward-backward mapping (FBM) referencing the General Equivalence Mappings to translate the outcome (angioedema) and covariates from ICD-9-CM to ICD-10-CM. We performed propensity score (PS)-matched and PS-stratified Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS In the ICD-9-CM and ICD-10-CM eras spanning April 1 to September 30 of 2015 and 2016, there were 152 017 and 145 232 angiotensin-converting enzyme inhibitor initiators and 115 073 and 116 652 beta-blocker initiators, respectively. The PS-matched HR was 4.19 (95% CI, 2.82-6.23) in the ICD-9-CM era, 4.37 (2.92-6.52) in the ICD-10-CM era using SFM, and 4.64 (3.05-7.07) in the ICD-10-CM era using SBM and FBM. The PS-matched HRs from the mixed ICD-9-CM and ICD-10-CM eras ranged from 3.91 (2.69-5.68) to 4.35 (3.33-5.70). CONCLUSION The adjusted HRs across different diagnostic coding eras and the use of SFM versus SBM and FBM produced numerically different but clinically similar results. Additional investigations as ICD-10-CM data accumulate are warranted.

Abstract
PURPOSE To describe the consistency in the frequency of 5 health outcomes across the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) and Tenth Revision, Clinical Modification (ICD-10-CM) eras in the US. METHODS We examined the incidence of 3 acute conditions (acute myocardial infarction [AMI], angioedema, ischemic stroke) and the prevalence of 2 chronic conditions (diabetes, hypertension) during the final 5 years of the ICD-9-CM era (January 2010-September 2015) and the first 15 months of the ICD-10-CM era (October 2015-December 2016) in 13 electronic health care databases in the Sentinel System. For each health outcome reviewed during the ICD-10-CM era, we evaluated 4 definitions, including published algorithms derived from other countries, as well as simple-forward, simple-backward, and forward-backward mapping using the General Equivalence Mappings. For acute conditions, we also compared the incidence between April to December 2014 and April to December 2016. RESULTS The analyses included data from approximately 172 million health plan members. While the incidence or prevalence of AMI and hypertension performed similarly across the 2 eras, the other 3 outcomes did not demonstrate consistent trends for some or all the ICD-10-CM definitions assessed. CONCLUSIONS When using data from both the ICD-9-CM and ICD-10-CM eras, or when using results from ICD-10-CM data to compare to results from ICD-9-CM data, researchers should test multiple ICD-10-CM outcome definitions as part of sensitivity analysis. Ongoing assessment of the impact of ICD-10-CM transition on identification of health outcomes in US electronic health care databases should occur as more data accrue.

Abstract
BACKGROUND Despite increasing awareness of the importance of a provider recommendation for HPV vaccine, the U.S. has yet to achieve the Healthy people 2020 goal of 80% series completion among adolescents. This failure indicates a need for further examination of the modifiable influences on parents' decision-making. Healthcare providers can influence parents' HPV vaccination decision-making, but little is known about parents' perspectives on the counseling they receive. We sought to assess U.S. parents' satisfaction with provider communication about HPV vaccine and associations with vaccination behaviors. METHODS Parents of 11-to-17-year-old adolescents who discussed HPV vaccination with a healthcare provider at least once (n = 795) completed our online survey in Fall 2016. We assessed their satisfaction with the discussion using the HPV Vaccine Communication Satisfaction Scale (α = 0.94). We examined associations between satisfaction (categorized as low, moderate, or high), and three vaccination behaviors: refusal/delay, series initiation (≥1 dose), and continuation (≥2 doses among initiators) using multivariable logistic regression. RESULTS Most parents reported high (36%) or moderate (38%) satisfaction with provider communication about HPV vaccination; fewer reported low (26%) satisfaction. Moderately satisfied parents (vs. low) had lower odds of refusal/delay (aOR = 0.59, 95% CI: 0.38-0.89), and higher odds of initiation (aOR = 1.71, 95% CI:1.15-2.55) and continuation (aOR = 2.05, 95% CI: 1.24-3.40). The associations were stronger for highly satisfied parents (refusal/delay aOR = 0.45, 95% CI: 0.29-0.70, initiation aOR = 3.59, 95% CI: 2.23-5.78, and continuation aOR = 4.08, 95% CI: 2.38-7.01). CONCLUSIONS Our study suggests that parent satisfaction with provider communication may play an important role in HPV vaccination decision-making. Yet, communication satisfaction has been largely unexamined in the HPV-vaccine literature to date. We introduce a brief, 7-item HPV Vaccine Communication Scale that can be used to assess parents' level of satisfaction with their provider's communication specific to HPV vaccine. We identify communication areas for providers to prioritize when discussing HPV vaccine with parents.

Abstract
PURPOSE The Food and Drug Administration's Sentinel System developed parameterized, reusable analytic programs for evaluation of medical product safety. Research on outpatient antibiotic exposures, and Clostridium difficile infection (CDI) with non-user reference groups led us to expect a higher rate of CDI among outpatient clindamycin users vs penicillin users. We evaluated the ability of the Cohort Identification and Descriptive Analysis and Propensity Score Matching tools to identify a higher rate of CDI among clindamycin users. METHODS We matched new users of outpatient dispensings of oral clindamycin or penicillin from 13 Data Partners 1:1 on propensity score and followed them for up to 60 days for development of CDI. We used Cox proportional hazards regression stratified by Data Partner and matched pair to compare CDI incidence. RESULTS Propensity score models at 3 Data Partners had convergence warnings and a limited range of predicted values. We excluded these Data Partners despite adequate covariate balance after matching. From the 10 Data Partners where these models converged without warnings, we identified 807 919 new clindamycin users and 8 815 441 new penicillin users eligible for the analysis. The stratified analysis of 807 769 matched pairs included 840 events among clindamycin users and 290 among penicillin users (hazard ratio 2.90, 95% confidence interval 2.53, 3.31). CONCLUSIONS This evaluation produced an expected result and identified several potential enhancements to the Propensity Score Matching tool. This study has important limitations. CDI risk may have been related to factors other than the inherent properties of the drugs, such as duration of use or subsequent exposures.

Abstract
Purpose of Review An important component of the Food and Drug Administration's Sentinel Initiative is the active post-market risk identification and analysis (ARIA) system, which utilizes semi-automated, parameterized computer programs to implement propensity-score adjusted and self-controlled risk interval designs to conduct targeted surveillance of medical products in the Sentinel Distributed Database. In this manuscript, we review literature relevant to the development of these programs and describe their application within the Sentinel Initiative. Recent Findings These quality-checked and publicly available tools have been successfully used to conduct rapid, replicable, and targeted safety analyses of several medical products. In addition to speed and reproducibility, use of semi-automated tools allows investigators to focus on decisions regarding key methodological parameters. We also identified challenges associated with the use of these methods in distributed and prospective datasets like the Sentinel Distributed Database, namely uncertainty regarding the optimal approach to estimating propensity scores in dynamic data among data partners of heterogeneous size. Summary Future research should focus on the methodological challenges raised by these applications as well as developing new modular programs for targeted surveillance of medical products.

Abstract
We demonstrate how direct, indirect, total, and overall effectiveness estimates and absolute benefits of rotavirus vaccines vary through the years following vaccine introduction. Privately insured US children in a large claims database were followed from age 8 months until they 1) experienced a hospitalization for rotavirus or acute gastroenteritis; 2) lost continuous health plan enrollment; 3) turned 20 months of age; or 4) reached the end of the study period. Vaccine effectiveness estimates in preventing rotavirus and acute gastroenteritis hospitalizations were estimated using Cox proportional hazards regression, stratified by calendar year and adjusted for birth month. Incidence rate differences were estimated to determine the absolute number of gastroenteritis hospitalizations prevented in the cohort. Among 905,718 children, 51%, 66%, 80%, and 86% received 1 or more doses of rotavirus vaccine in each year from 2007 to 2010. The direct vaccine effectiveness of 1 or more doses of rotavirus vaccine in preventing rotavirus gastroenteritis hospitalizations ranged from 87% to 92% each year. Accounting for indirect protection increased estimates of vaccine effectiveness by an additional 3%-8% among those vaccinated. Failing to account for population-level vaccine benefits in 2010, when circulation of rotavirus was low, could underestimate the sustained impact of the vaccine program.

Abstract
OBJECTIVES To conduct outcome and process evaluations of school-located HPV vaccination clinics in partnership with a local health department. METHODS Temporary clinics provided the HPV vaccine to middle school girls in Guilford County, North Carolina, in 2009-2010. RESULTS HPV vaccine initiation was higher among girls attending host schools than satellite schools (6% vs. 1%, OR = 6.56, CI = 3.99-10.78). Of the girls who initiated HPV vaccine, 80% received all 3 doses. Private insurance or federal programs paid for most vaccine doses. CONCLUSIONS Lessons learned for creating more effective school-health department partnerships include focusing on host schools and delivering several vaccines to adolescents, not just HPV vaccine alone.

Abstract
Rotavirus vaccines are highly effective at preventing gastroenteritis in young children and are now universally recommended for infants in the US. We studied patterns of use of rotavirus vaccines among US infants with commercial insurance. We identified a large cohort of infants in the MarketScan Research Databases, 2006-2010. The analysis was restricted to infants residing in states without state-funded rotavirus vaccination programs. We computed summary statistics and used multivariable regression to assess the association between patient-, provider-, and ecologic-level variables of rotavirus vaccine receipt and series completion. Approximately 69% of 594,117 eligible infants received at least one dose of rotavirus vaccine from 2006-2010. Most infants received the rotavirus vaccines at the recommended ages, but more infants completed the series for monovalent rotavirus vaccine than pentavalent rotavirus vaccine or a mix of the vaccines (87% versus 79% versus 73%, P<0.001). In multivariable analyses, the strongest predictors of rotavirus vaccine series initiation and completion were receipt of the diphtheria, tetanus and acellular pertussis vaccine (Initiation: RR = 7.91, 95% CI = 7.69-8.13; Completion: RR = 1.26, 95% CI = 1.23-1.29), visiting a pediatrician versus family physician (Initiation: RR = 1.51, 95% CI = 1.49-1.52; Completion: RR = 1.13, 95% CI = 1.11-1.14), and living in a large metropolitan versus smaller metropolitan, urban, or rural area. We observed rapid diffusion of the rotavirus vaccine in routine practice; however, approximately one-fifth of infants did not receive at least one dose of vaccine as recently as 2010. Interventions to increase rotavirus vaccine coverage should consider targeting family physicians and encouraging completion of the vaccine series.

Abstract
To confirm whether respiratory virus infections increase susceptibility to invasive pneumococcal pneumonia, we examined data from 11 influenza seasons (1994-2005) in the United States. Invasive pneumococcal pneumonia was significantly associated with influenza and respiratory syncytial virus activities in 5 seasons. Association strength was higher when strain H3N2 was the predominant influenza A virus strain.

Abstract
BACKGROUND Increasing knowledge about human papillomavirus (HPV) and HPV vaccine is a potentially important way to increase vaccination rates, yet few education interventions have addressed these topics. We report the results of an education intervention targeting three key groups who have contact with adolescent females. METHODS We conducted HPV education intervention sessions during 2008 and 2009 in Guilford County, North Carolina. Parents (n = 376), healthcare staff (n = 118), and school staff (n = 456) attended the one-time sessions and completed self-administered surveys. Analyses used mixed regression models to examine the intervention's effects on participants' self-rated HPV knowledge, objectively assessed HPV and HPV vaccine knowledge, and beliefs about HPV vaccine. RESULTS Participants had relatively low levels of objectively assessed HPV and HPV vaccine knowledge prior to the intervention. The education intervention increased self-rated HPV knowledge among all three key groups (all P < 0.001), and objectively assessed knowledge about many aspects of HPV and HPV vaccine among healthcare and school staff members (all P < 0.05). Following the intervention, more than 90% of school staff members believed HPV and HPV vaccine education is worthwhile for school personnel and that middle schools are an appropriate venue for this education. Most parents (97%) and school staff members (85%) indicated they would be supportive of school-based vaccination clinics. CONCLUSIONS Our education intervention greatly increased HPV and HPV vaccine knowledge among groups influential to the HPV vaccination behaviors of adolescent females. IMPACT Education interventions represent a simple yet potentially effective strategy for increasing HPV vaccination and garnering stronger support for school-based vaccination clinics.

Abstract
Background: Increasing knowledge about HPV and HPV vaccine is a potentially important way to increase vaccination rates, yet few education interventions have addressed these topics. We report the results of an education intervention targeting three key groups who have contact with adolescent females.
Methods: We conducted HPV education intervention sessions during 2008 and 2009 in Guilford County, North Carolina. Guilford County has a higher proportion of African American residents compared to North Carolina as a whole, as well as one of the highest cervical cancer mortality rates in the state. Parents (n=376), healthcare staff (n=118), and school staff (n=456) attended the one-time education sessions and completed self-administered surveys. Analyses used mixed regression models.
Results: Participants had relatively low levels of objectively assessed HPV and HPV vaccine knowledge prior to the intervention. The education intervention increased self-rated HPV knowledge among all three key groups (all p<0.001), as well as objectively assessed knowledge about many aspects of HPV and HPV vaccine among healthcare and school staff members (all p<0.05). Although all groups experienced an increase in their self-rated knowledge, the largest increase was seen among parents, with healthcare and school staff experiencing smaller increases (p<0.05). Following the intervention, over 90% of school staff members believed HPV and HPV vaccine education is worthwhile for school personnel and that middle schools are an appropriate venue for this education. Most parents (97%) and school staff members (85%) indicated they would be supportive of school-based vaccination clinics.
Discussion: An important first step in increasing HPV vaccination rates among adolescent females in the US is to improve knowledge levels among key groups influential to adolescents’ vaccination behaviors. In this study, we demonstrated that a simple education intervention greatly improved objectively assessed and self-rated HPV and HPV vaccine knowledge levels among parents, healthcare staff, and school staff members. Such interventions offer a relatively low effort and potentially effective strategy for increasing HPV vaccination.

Abstract
BACKGROUND Following implementation of the rotavirus vaccination program in 2006, rotavirus activity in the United States declined dramatically in 2007-2008 but increased slightly in 2008-2009, despite greater vaccine uptake. To further evaluate impact of the vaccine program, we assessed trends in rotavirus testing and detection during 2009-2010. METHODS We examined rotavirus testing data from July 2000 to June 2010 from the National Respiratory and Enteric Viruses Surveillance System to compare rotavirus season timing and peak activity in the pre- and postvaccine introduction eras. Rotavirus season onset was defined as the first of 2 consecutive weeks during which the percentage of specimens testing positive for rotavirus was ≥ 10%. To assess trends in rotavirus testing and detection, we restricted the analyses to 25 laboratories that reported for ≥ 26 weeks per season from 2000 to 2010. RESULTS During 2009-2010, the threshold for the start of the rotavirus season was never achieved nationally or in the North, Midwest, or West. Activity in the South met this threshold but the season duration was substantially shorter and of lower magnitude than in all previous pre- and postvaccine introduction seasons. Nationally and within each region, the peak week was more delayed and the peak proportion of positive tests was substantially lower than all previous seasons. The total number of tests performed declined by 23%, and the number of positive tests declined by 86%. CONCLUSIONS Rotavirus activity was substantially diminished during the 2009-2010 rotavirus season compared with the prevaccine baseline and the 2 previous postvaccine introduction seasons. These sustained declines over 3 rotavirus seasons reaffirm the health benefits of the US rotavirus vaccination program.

Abstract
BACKGROUND In September 2008, an outbreak of pneumonia associated with an emerging human adenovirus (human adenovirus serotype 14 [HAdV-14]) occurred on a rural Southeast Alaska island. Nine patients required hospitalization, and 1 patient died. METHODS To investigate the outbreak, pneumonia case patients were matched to control participants on the basis of age, sex, and community of residence. Participants in the investigation and their household contacts were interviewed, and serum samples and respiratory tract specimens were collected. Risk factors were evaluated by means of conditional logistic regression. RESULTS Among 32 pneumonia case patients, 21 (65%) had confirmed or probable HAdV-14 infection. None of 32 matched control participants had evidence of HAdV-14 infection (P<.001 for the difference). Factors independently associated with pneumonia included contact with a known HAdV-14-infected case patient (odds ratio [OR], 18.3 [95% confidence interval {CI}, >or=2.0]), current smoking (OR, 6.7 [95% CI, >or=0.9]), and having neither traveled off the island nor attended a large public gathering (OR, 14.7 [95% CI, >or=2.0]). Fourteen (67%) of 21 HAdV-14-positive case patients belonged to a single network of people who socialized and often smoked together and infrequently traveled off the island. HAdV-14 infection occurred in 43% of case-patient household contacts, compared with 5% of control-participant household contacts (P = .005). CONCLUSIONS During a community outbreak in Alaska, HAdV-14 appeared to have spread mostly among close contacts and not widely in the community. Demographic characteristics and illness patterns among the case patients were similar to those observed in other recent outbreaks of HAdV-14 infection in the United States.

Abstract
OBJECTIVE For children in the United States who are at high risk for severe respiratory syncytial virus (RSV) infection, the American Academy of Pediatrics (AAP) recommends administering immunoprophylaxis during the RSV season. We present an approach to using surveillance data to help guide application of AAP recommendations for immunoprophylaxis to local patterns of RSV outbreaks. METHODS We analyzed data from laboratories that report consistently to the National Respiratory and Enteric Virus Surveillance System from 1992 to 2007. Local RSV seasons were defined and an immunoprophylaxis schedule was determined by using the median onset dates from each laboratory during 2002-2007. We applied these dates to 10 preceding years of RSV detection data. We compared how well the 5-year median-based method and a fixed date method were able to match the timing of immunoprophylaxis to the RSV season. RESULTS Nineteen laboratories met our inclusion criteria and generally experienced only 1 RSV outbreak per season. Five years of data gave similar median onset/offset dates and season duration, as did 10 years and 15 years of data. The 5-year median schedule increased the number of seasons that children were protected at the season onset by 15% compared with a fixed start date of November 1 and identified communities that experienced RSV seasons with extended durations. CONCLUSIONS The 5-year median method can be used to characterize timing of RSV seasons and optimally apply the current AAP recommendations for timing of palivizumab prophylaxis to the local community.

Abstract
BACKGROUND In 2006, routine immunization of US infants against rotavirus was initiated. We assessed national, regional, and local trends in rotavirus testing and detection before and after vaccine introduction. METHODS We examined data for July 2000 through June 2008 from a national network of approximately 70 US laboratories to compare geographical and temporal aspects of rotavirus season timing and peak activity. To assess trends in rotavirus testing and detection, we restricted the analyses to 33 laboratories that reported for >or=26 weeks per season from 2000 to 2008. RESULTS Nationally, the onset and peak of the 2007-2008 rotavirus season were delayed 15 and 8 weeks, respectively, compared with prevaccine seasons from 2000-2006. Delays were observed in each region. The 2007-2008 rotavirus season lasted 14 weeks compared with a median of 26 weeks during the prevaccine era. Of 33 laboratories, 32 reported fewer positive results and a lower proportion of positive test results in 2007-2008 compared with the median in 2000-2006, with a 67% decline in the number and a 69% decline in the proportion of rotavirus-positive test results. The proportion of positive test results in 2007-2008 compared with the median in 2000-2006 declined >50% in 79% of the laboratories and >75% in 39% of the laboratories. CONCLUSIONS The 2007-2008 US rotavirus season seems substantially delayed, shorter, and diminished in magnitude compared with seasons before vaccine implementation. The extent of change seems greater than expected on the basis of estimated vaccine coverage, suggesting indirect benefits to unvaccinated individuals. Monitoring in future seasons is needed to confirm these trends.

Abstract
BACKGROUND In 2007, a US Air Force training facility reported a cluster of severe respiratory illnesses associated with a rare human adenovirus (Ad) serotype, Ad14. We investigated this outbreak to better understand its epidemiology, clinical spectrum, and associated risk factors. METHODS Data were collected from ongoing febrile respiratory illness (FRI) surveillance and from a retrospective cohort investigation. Because an Ad7 vaccine is in development, Ad7 antibody titers in pretraining serum samples from trainees with mild and those with severe Ad14 illness were compared. RESULTS During 2007, an estimated 551 (48%) of 1147 trainees with FRI were infected with Ad14; 23 were hospitalized with pneumonia, 4 required admission to an intensive care unit, and 1 died. Among cohort members (n = 173), the Ad14 infection rate was high (50%). Of those infected, 40% experienced FRI. No cohort members were hospitalized. Male sex (risk ratio [RR], 4.7 [95% confidence interval {CI}, 2.2-10.1]) and an ill close contact (RR, 1.6 [95% CI, 1.2-2.2]) were associated with infection. Preexisting Ad7 neutralizing antibodies were found in 7 (37%) of 19 Ad14-positive trainees with mild illness but in 0 of 16 trainees with Ad14 pneumonia (P = .007). CONCLUSIONS Emergence of Ad14, a rare Ad serotype, caused a protracted outbreak of respiratory illness among military recruits. Most infected recruits experienced FRI or milder illnesses. Some required hospitalization, and 1 died. Natural Ad7 infection may protect against severe Ad14 illness.

Abstract
Historically, annual rotavirus activity in the United States has started in the southwest in late fall and ended in the northeast 3 months later; this trend has diminished in recent years. Traveling waves of infection or local environmental drivers cannot account for these patterns. A transmission model calibrated against epidemiological data shows that spatiotemporal variation in birth rate can explain the timing of rotavirus epidemics. The recent large-scale introduction of rotavirus vaccination provides a natural experiment to further test the impact of susceptible recruitment on disease dynamics. The model predicts a pattern of reduced and lagged epidemics postvaccination, closely matching the observed dynamics. Armed with this validated model, we explore the relative importance of direct and indirect protection, a key issue in determining the worldwide benefits of vaccination.
