However, vaccination coverage among U.S. kindergartners has decreased from 95.2% during the 2019–2020 school year to 92.4% in the 2025–2026 school year, leaving approximately 280,000 kindergartners at risk during the 2025–2026 school year.
Children’s National receives $56.25 million Pediatric Prevention Network award
14, 2026 (GLOBE NEWSWIRE) -- Children’s National will receive $56.25 million over five years to help lead the Pediatric Prevention Network’s (PPN) work to strengthen pediatric disaster preparedness and improve access to high-quality care for children nationwide. Formerly known as...
U.S. News & World Report Marks 20 Years of Pediatric Care Rankings with the 2026-2027 Best Children's Hospitals
90 children's hospitals recognized across 34 states and Washington, D.C., for exceptional pediatric care. 11 pediatric medical specialties evaluated, including the third annual evaluation of pediatric and adolescent behavioral health programs.
Research of the Day
Naturalistic Developmental Behavioral Interventions Before Age 2: RCT
This RCT provided Naturalistic Developmental Behavioral Interventions (NDBI) to infants showing early autism markers at 12-18 months. Early intervention significantly improved social communication outcomes at age 3.
Key findings: (1) 40% of intervention group no longer met ASD criteria at age 3; (2) Greater gains when started before 15 months; (3) Parent-mediated strategies effective when coached by professionals.
Refer promptly when developmental concerns arise—don't wait for definitive diagnosis. Early intervention can meaningfully change trajectories. Coach parents to implement strategies in daily routines.
Popular Beliefs
Shaving makes hair grow back thicker and darker
What the evidence shows: Shaving removes hair at the skin surface, leaving a blunt tip that may feel coarser as it grows out. However, it does not affect hair thickness, color, or growth rate. This is an optical illusion from the blunt vs. tapered hair shaft.
Reading to babies is pointless—they don't understand
What the evidence shows: Research consistently demonstrates that reading to infants from birth supports language development, vocabulary acquisition, and later literacy skills. Even before understanding words, babies benefit from hearing language patterns, rhythm, and the bonding experience. The AAP recommends reading aloud beginning in infancy.
Too many vaccines overwhelm a child's immune system
What the evidence shows: Children's immune systems handle vastly more antigens daily from the environment than from vaccines. Today's vaccines contain far fewer antigens than older versions despite protecting against more diseases. Studies show no increased infection rates in vaccinated children—vaccines strengthen, not weaken, immunity.
Behaviors
Early Pet Exposure and Immune Development: Birth Cohort Study
This birth cohort followed 1,200 children from birth to age 5, comparing immune development and allergy rates in homes with and without pets. Early pet exposure was associated with reduced allergy risk and altered gut microbiome.
Key findings: (1) 30% lower allergic sensitization with dog exposure in first year; (2) Cat exposure showed similar but smaller effects; (3) Microbiome diversity increased in pet-exposed children.
Reassure families that pet exposure during infancy may actually protect against allergies. For families without pets, don't specifically recommend getting one, but dispel the myth that pets must be removed to prevent allergies.
Genetics
CFTR Modulator Therapy in Young Children: Expansion to Additional Mutations
New clinical trial data supports expanding CFTR modulator therapy to children as young as 1 year with various CFTR mutations. Early treatment initiation shows benefits in lung function preservation and nutritional status, with excellent safety profile.
Key findings: (1) 85% of CF patients now eligible for modulator therapy; (2) Early treatment prevents rather than reverses lung damage; (3) Growth parameters improved in treated toddlers.
Refer CF patients promptly for genetic classification and modulator eligibility assessment. The treatment landscape has transformed—many children can now expect near-normal life expectancy with appropriate therapy.
