The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts that provides advice to the Centers for Disease Control and Prevention, normally meets 3 times per year to develop US vaccine recommendations. The ACIP met October 23-24, 2024, to discuss influenza vaccines, chikungunya vaccines, coronavirus disease (COVID-19) vaccines, RSV immunizations, meningococcal vaccines, human papillomavirus (HPV) vaccines, pneumococcal vaccines, and adult and child/adolescent immunization schedule revisions. This update summarizes the proceedings of these meetings, with an emphasis on topics that are most relevant to the pediatric population. Major updates for pediatric clinicians include information regarding COVID-19 and influenza vaccine recommendations, meningococcal vaccination considerations, and updates regarding implementation and effectiveness of RSV immunization in pregnant people and infants.

Background and objectives: Learning difficulties are frequently reported in children with neurofibromatosis type 1 (NF1), yet little is known about the extent and predictors of their academic functions across ages. We aimed to examine the developmental patterns of academic achievement in these children from childhood to adolescence and how these patterns differ across demographic and NF1-related disease factors.

Methods: This cross-sectional study integrated data of 1512 children with NF1 (mean age, 11.2 years, SD, 3.62, range, 3-18, 46.5% female patients) from 8 institutions. Academic functioning was assessed with Woodcock-Johnson Tests of Achievement or the Wechsler Individual Achievement Test. Data were analyzed primarily using time-varying effect modeling.

Results: Participants' academic achievement was significantly lower than the normative means across ages, and the gap widened from middle childhood to midadolescence. Academic age trends varied across academic domains and demographic and disease factors. Male patients demonstrated larger deviations in math at midchildhood and in reading and writing between midchildhood and midadolescence. Children with lower parental education demonstrated larger deviations in math, reading, and writing between midchildhood and midadolescence. Children with familial NF1 demonstrated larger deviations in math at midchildhood and mid-to-late-adolescence, and in reading and writing between midchildhood and midadolescence.

Conclusions: Academic difficulties in children with NF1 emerge early and worsen with age. The findings also highlight the variability within this population across demographic and disease factors. The age-specific estimates of academic functions can serve as the first NF1-specific academic norms, providing useful insights for future research and practice.

Objectives: To compare incidence of late-onset sepsis (LOS) among extremely preterm infants before and during the COVID-19 pandemic.

Methods: Multicenter cohort study of infants with birthweight 401 to 1000 g or gestational age 22 to 28 weeks. LOS was defined as a bacterial or fungal pathogen isolated from blood or cerebrospinal fluid culture obtained after 72 hours of age. Primary outcome was LOS incidence calculated as incidence proportion (LOS cases among all admissions) and incidence rate (LOS events/1000 patient days). A multivariable Poisson regression model was used to compare the adjusted risk of LOS incidence proportion before (1/1/18-3/31/20) and during the pandemic (4/1/20-12/31/21). An interrupted time series analysis using a generalized linear mixed model with center as a random effect was used to compare LOS incidence rates during the 2 periods.

Results: Among 6509 eligible infants, LOS incidence proportion was not different before (18.2%) and during the pandemic (16.9%; P = .18). The adjusted relative risk (95% CI) for LOS was 0.93 (0.82-1.05) and for LOS or mortality was 0.98 (0.88-1.08) during the pandemic compared to the period before the pandemic. In the interrupted time series analysis, there was no significant change in LOS incidence rates at the start of the pandemic (0.219, 95% CI, -0.453 to 0.891) or microbiology of LOS, and change in trends of LOS incidence rates before and during the pandemic was not significant (-0.005, 95% CI, -0.025 to 0.015).

Conclusions: In a large multicenter study of extremely preterm infants, rates of LOS remained unchanged during the pandemic.
