Pediatricians and Health Departments Sidestep Trump’s CDC on Vaccine Guidance - KFF Health News
On Jan. 5, the CDC removed some vaccines from the recommended vaccine schedule for all children — against the advice of major medical groups like the American Academy of Pediatrics.

Research of the Day
Iron Deficiency in Infancy and Long-Term Cognitive Outcomes: 10-Year Follow-Up
This prospective cohort followed children with iron deficiency anemia in infancy through age 10, comparing cognitive outcomes to iron-sufficient peers. Despite iron repletion in infancy, children with early anemia showed persistent differences in executive function and spatial memory.
Key findings: (1) Early iron deficiency associated with lower scores on math and reading assessments; (2) Differences in brain structure observed on MRI at age 10; (3) Duration of deficiency correlated with magnitude of effect.
Emphasize prevention through dietary counseling and appropriate screening. Iron-rich complementary foods should be introduced at 6 months. Consider iron supplementation in high-risk populations.
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.
Cracking knuckles causes arthritis
What the evidence shows: Studies comparing habitual knuckle-crackers to non-crackers found no increased arthritis risk. The cracking sound is from gas bubble release in synovial fluid. The main consequence may be reduced grip strength and annoyed family members.
The flu shot can give you the flu
What the evidence shows: Flu vaccines contain inactivated virus or viral proteins that cannot cause influenza infection. Some people experience mild side effects (sore arm, low-grade fever) that mimic illness. It takes 2 weeks for protection to develop, so some may get infected before the vaccine works.
Behaviors
Growth Mindset and Academic Resilience in Middle School
This school-based intervention taught growth mindset principles to 4,000 middle schoolers. Students who internalized growth mindset showed improved grades, greater persistence, and reduced anxiety around academic challenges.
Key findings: (1) 0.3 GPA improvement in intervention group; (2) 25% reduction in test anxiety; (3) Effects largest for initially low-performing students. Teacher reinforcement of messages enhanced effects.
Praise effort over ability when discussing academics with patients. Encourage families to use growth mindset language. Struggle is part of learning, not a sign of inability.

Gene Therapy Shows Promise for Spinal Muscular Atrophy Type 1
Long-term follow-up data from the Phase 3 clinical trial of onasemnogene abeparvovec gene therapy reveals sustained motor milestone achievements in children with SMA Type 1 treated before 6 months of age. At 5-year follow-up, 94% of early-treated patients maintained the ability to sit independently, and 68% achieved independent walking—outcomes historically unprecedented in untreated SMA Type 1.
The study also reports on safety outcomes, with no new treatment-related serious adverse events emerging after year 2. These results strengthen the case for newborn screening and early intervention in SMA.
This data reinforces the critical importance of early diagnosis and treatment in SMA. Support newborn screening initiatives in your state. For families with SMA history, discuss carrier testing and ensure rapid referral to neuromuscular specialists if symptoms arise.
