"COVID Vaccines Slashed Kids’ ER Visits by 76%, Study Finds" Effectiveness of COVID Vaccines in Children (compared with unvaccinated children): 🔹76% reduction in ER or urgent care visits (ages 9 months–4 years) 🔹56% reduction in ER or Urgent care visits (ages 5–17 years) Source: archive.md/roPXg
A screenshot of a Scientific American article titled “COVID Vaccines Slashed Kids’ ER Visits by 76 Percent, Study Finds.” The subheading notes that a CDC report reaffirms the effectiveness of COVID vaccines at preventing severe disease in children. The article is dated December 11, 2025 and credited to Tanya Lewis, edited by Andrea Thompson.

Below the headline is a photo showing a child’s hand pointing at a row of colorful Band-Aids laid out on a medical table. The Band-Aids come in various bright patterns—zebra stripes, red with shapes, blue designs, cartoon-style prints, floral prints, green camouflage, and two yellow ones. The table has a white medical pad, and nearby are some clinic items such as a phone or device and other equipment. The caption states that the image shows a child picking out a Band-Aid before receiving a COVID vaccination in San Jose, California in 2022.

A generation at risk: Food crises in Gaza and elsewhere put millions of children in danger of lifelong harm
A surge in the flow of aid into the Gaza Strip since the truce between Israel and Hamas took effect on Jan. 19 is likely to ease the acute food emergency afflicting people in the war-ravaged territory, especially its children. But even after relief reaches them, the hunger they have endured could cast a shadow over their health for years to come.
