Covid-19 vaccines delayed for about half of US children as access through federal program stalls - NewsBreak
A pediatric Covid-19 vaccine would cost $149.99 out-of-pocket with no insurance coverage, CVS said. Dr. Michelle Fiscus, chief medical officer of the Association of Immunization Managers, said there is always some delay between when seasonal vaccines are available commercially an...
Pediatricians raise the alarm on the effect of Trump's immigration crackdown on kids | KPBS Public Media
A new national survey, conducted between April and June 2026 by the American Academy of Pediatrics, found that 40% of pediatricians have noticed families staying away from care due to immigration concerns.

Research of the Day
Probiotics for Infantile Colic: Randomized Controlled Trial of L. reuteri
This double-blind RCT enrolled 400 breastfed infants with colic to evaluate Lactobacillus reuteri supplementation. Infants receiving the probiotic showed significantly reduced crying time compared to placebo, with effects observed within 7 days of treatment initiation.
Key findings: (1) Mean crying time reduced by 51 minutes/day at 21 days; (2) 73% of treatment group had crying <3 hours/day vs 36% placebo; (3) No adverse events reported. Effect was specific to breastfed infants.
L. reuteri may be considered for breastfed infants with colic after excluding other causes. This is one of several evidence-based interventions alongside feeding adjustments, carrying techniques, and parental support.
Popular Beliefs
Chocolate causes acne
What the evidence shows: The relationship between diet and acne is complex. Some studies suggest high-glycemic diets and dairy may worsen acne, but chocolate specifically has not been definitively proven to cause breakouts. Individual responses vary—advise patients to observe their own triggers.
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.
Vaccines cause autism
What the evidence shows: This thoroughly debunked claim originated from a fraudulent 1998 study. Multiple large-scale studies involving millions of children have found no association between vaccines and autism. The original study was retracted and its author lost his medical license. Vaccines are safe and essential.
Behaviors
Secondhand Smoke Exposure and Cognitive Development: Cohort Study
This cohort study measured cotinine levels and cognitive outcomes in 2,000 children at multiple time points. Even low-level secondhand smoke exposure was associated with measurable effects on attention and working memory.
Key findings: (1) Detectable cotinine associated with 5-point IQ difference; (2) Higher rates of learning difficulties; (3) No safe threshold identified—any exposure had measurable effects.
Screen for smoke exposure at well visits. Counsel caregivers that even 'smoking outside' may not fully protect children. Connect families with smoking cessation resources.
Genetics
Genetic Predictors of Peanut Allergy Persistence
Genome-wide association study identifies genetic variants associated with peanut allergy persistence versus resolution. Children with certain variants are more likely to outgrow their allergy, informing timing of oral food challenges.
Key findings: (1) 4 genetic variants strongly associated with persistence; (2) Genetic testing could reduce unnecessary avoidance and challenges; (3) Environmental factors remain important in allergy development.
Genetic testing may soon help predict which children will outgrow allergies. For now, continue regular reassessment with IgE testing and oral challenges as clinically indicated.
