Pediatrics 2022 150 (2) BACKGROUND AND OBJECTIVES: Limited post-authorization safety data for BNT-162b2 COVID-19 vaccination among children ages 5-11 years are available, particularly for the adverse event myocarditis, which has been detected in adolescents and young adults. We describe adverse events observed during the first 4 months of the US COVID-19 vaccination program in this age group. METHODS: We analyzed data from 3 US safety monitoring systems: v-safe, a voluntary smartphone-based system that monitors reactions and health effects; the Vaccine Adverse Events Reporting System (VAERS), the national spontaneous reporting system co-managed by CDC and FDA; and the Vaccine Safety Datalink (VSD), an active surveillance system that monitors electronic health records for prespecified events, including myocarditis. RESULTS: Among 48,795 children ages 5-11 years enrolled in v-safe, most reported reactions were mild-to-moderate, most frequently reported the day after vaccination, and were more common after dose 2. VAERS received 7,578 adverse event reports; 97% were non-serious. On review of 194 serious VAERS reports, 15 myocarditis cases were verified; 8 occurred in males after dose 2 (reporting rate 2.2 per million doses). In VSD, no safety signals were detected in weekly sequential monitoring after administration of 726,820 doses. CONCLUSIONS: Safety findings for BNT-162b2 vaccine from 3 US monitoring systems in children ages 5-11 years show that most reported adverse events were mild and no safety signals were observed in active surveillance. VAERS reporting rates of myocarditis after dose 2 in this age group were substantially lower than those observed among adolescents ages 12-15 years. |
Safety Monitoring of COVID-19 Vaccine Booster Doses Among Persons Aged 12-17 Years - United States, December 9, 2021-February 20, 2022.
Hause AM , Baggs J , Marquez P , Abara WE , Olubajo B , Myers TR , Su JR , Thompson D , Gee J , Shimabukuro TT , Shay DK . MMWR Morb Mortal Wkly Rep 2022 71 (9) 347-351 As of February 20, 2022, only BNT162b2 (Pfizer-BioNTech) COVID-19 vaccine has been authorized for use in persons aged 12-17 years in the United States (1). The Food and Drug Administration (FDA) amended the Emergency Use Authorization (EUA) for Pfizer-BioNTech vaccine on December 9, 2021, to authorize a homologous* booster dose for persons aged 16-17 years ≥6 months after receipt of dose 2 (1). On January 3, 2022, authorization was expanded to include persons aged 12-15 years, and for all persons aged ≥12 years, the interval between dose 2 and booster dose was shortened to ≥5 months (1). To characterize the safety of Pfizer-BioNTech booster doses among persons aged 12-17 years (adolescents), CDC reviewed adverse events and health impact assessments during the week after receipt of a homologous Pfizer-BioNTech booster dose reported to v-safe, a voluntary smartphone-based safety surveillance system for adverse events after COVID-19 vaccination, and adverse events reported to the Vaccine Adverse Event Reporting System (VAERS), a passive vaccine safety surveillance system managed by CDC and FDA. During December 9, 2021-February 20, 2022, approximately 2.8 million U.S. adolescents received a Pfizer-BioNTech booster dose.(†) During this period, receipt of 3,418 Pfizer-BioNTech booster doses were reported to v-safe for adolescents. Reactions were reported to v-safe with equal or slightly higher frequency after receipt of a booster dose than after dose 2, were primarily mild to moderate in severity, and were most frequently reported the day after vaccination. VAERS received 914 reports of adverse events after Pfizer-BioNTech booster dose vaccination of adolescents; 837 (91.6%) were nonserious and 77 (8.4%) were serious. Health care providers, parents, and adolescents should be advised that local and systemic reactions are expected among adolescents after homologous Pfizer-BioNTech booster vaccination, and that serious adverse events are rare. |
National estimates of healthcare costs associated with multidrug-resistant bacterial infections among hospitalized patients in the United States
Nelson RE , Hatfield KM , Wolford H , Samore MH , Scott RD , Reddy SC , Olubajo B , Paul P , Jernigan JA , Baggs J . Clin Infect Dis 2021 72 S17-s26 BACKGROUND: Treating patients with infections due to multidrug-resistant pathogens often requires substantial healthcare resources. The purpose of this study was to report estimates of the healthcare costs associated with infections due to multidrug-resistant bacteria in the United States (US). METHODS: We performed retrospective cohort studies of patients admitted for inpatient stays in the Department of Veterans Affairs healthcare system between January 2007 and October 2015. We performed multivariable generalized linear models to estimate the attributable cost by comparing outcomes in patients with and without positive cultures for multidrug-resistant bacteria. Finally, we multiplied these pathogen-specific, per-infection attributable cost estimates by national counts of infections due to each pathogen from patients hospitalized in a cohort of 722 US hospitals from 2017 to generate estimates of the population-level healthcare costs in the US attributable to these infections. RESULTS: Our analysis cohort consisted of 16 676 patients with community-onset infections and 172 712 matched controls and 8246 patients with hospital-onset infections and 66 939 matched controls. The highest cost was seen in hospital-onset invasive infections, with attributable costs (95% confidence intervals) ranging from $30 998 ($25 272-$36 724) for methicillin-resistant Staphylococcus aureus to $74 306 ($20 377-$128 235) for carbapenem-resistant (CR) Acinetobacter. The highest attributable costs for community-onset invasive infections were seen in CR Acinetobacter ($62 396; $20 370-$104 422). Treatment of these infections cost an estimated $4.6 billion ($4.1 billion-$5.1 billion) in 2017 in the US for community- and hospital-onset infections combined. CONCLUSIONS: We found that antimicrobial-resistant infections led to substantial healthcare costs. |
Multidrug-resistant bacterial infections in U.S. hospitalized patients, 2012-2017
Jernigan JA , Hatfield KM , Wolford H , Nelson RE , Olubajo B , Reddy SC , McCarthy N , Paul P , McDonald LC , Kallen A , Fiore A , Craig M , Baggs J . N Engl J Med 2020 382 (14) 1309-1319 BACKGROUND: Multidrug-resistant (MDR) bacteria that are commonly associated with health care cause a substantial health burden. Updated national estimates for this group of pathogens are needed to inform public health action. METHODS: Using data from patients hospitalized in a cohort of 890 U.S. hospitals during the period 2012-2017, we generated national case counts for both hospital-onset and community-onset infections caused by methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococcus (VRE), extended-spectrum cephalosporin resistance in Enterobacteriaceae suggestive of extended-spectrum beta-lactamase (ESBL) production, carbapenem-resistant Enterobacteriaceae, carbapenem-resistant acinetobacter species, and MDR Pseudomonas aeruginosa. RESULTS: The hospital cohort in the study accounted for 41.6 million hospitalizations (>20% of U.S. hospitalizations annually). The overall rate of clinical cultures was 292 cultures per 1000 patient-days and was stable throughout the time period. In 2017, these pathogens caused an estimated 622,390 infections (95% confidence interval [CI], 579,125 to 665,655) among hospitalized patients. Of these infections, 517,818 (83%) had their onset in the community, and 104,572 (17%) had their onset in the hospital. MRSA and ESBL infections accounted for the majority of the infections (52% and 32%, respectively). Between 2012 and 2017, the incidence decreased for MRSA infection (from 114.18 to 93.68 cases per 10,000 hospitalizations), VRE infection (from 24.15 to 15.76 per 10,000), carbapenem-resistant acinetobacter species infection (from 3.33 to 2.47 per 10,000), and MDR P. aeruginosa infection (from 13.10 to 9.43 per 10,000), with decreases ranging from -20.5% to -39.2%. The incidence of carbapenem-resistant Enterobacteriaceae infection did not change significantly (from 3.36 to 3.79 cases per 10,000 hospitalizations). The incidence of ESBL infection increased by 53.3% (from 37.55 to 57.12 cases per 10,000 hospitalizations), a change driven by an increase in community-onset cases. CONCLUSIONS: Health care-associated antimicrobial resistance places a substantial burden on patients in the United States. Further work is needed to identify improved interventions for both the inpatient and outpatient settings. (Funded by the Centers for Disease Control and Prevention.). |
Implementation of evidence-based HIV interventions for gay, bisexual, and other men who have sex with men
Jeffries WL IV , Garrett S , Phields M , Olubajo B , Lemon E , Valdes-Salgado R , Collins CB Jr . AIDS Behav 2017 21 (10) 3000-3012 The Centers for Disease Control and Prevention provides trainings to support implementation of five evidence-based HIV prevention interventions (EBIs) for men who have sex with men (MSM): d-up: Defend Yourself!; Many Men, Many Voices; Mpowerment; Personalized Cognitive Counseling; and Popular Opinion Leader. We evaluated trainees' implementation of these EBIs and, using multivariable logistic regression, examined factors associated with implementation. Approximately 43% of trainees had implemented the EBIs for which they received training. Implementation was associated with working in community-based organizations (vs. health departments or other settings); acquiring training for Mpowerment or Popular Opinion Leader (vs. Personalized Cognitive Counseling); having ≥3 funding sources (vs. one); and having (vs. not having) sufficient time and necessary EBI resources. Findings suggest that implementation may vary by trainee characteristics, especially those related to employment setting, EBI training, funding, and perceived implementation barriers. Efforts that address these factors may help to improve EBI implementation among trainees. |
