HEALTH: Growing number of U.S. children not vaccinated against any disease.

An estimated 100,000 young children have not had a vaccination against any of the 14 diseases for which shots are recommended, according to a Centers for Disease Control and Prevention report released Thursday.

“This is pretty concerning. It’s something we need to understand better — and reduce,” said the CDC’s Dr. Amanda Cohn.

Most young children — 70 percent — have had all their shots. The new estimate is based on finding that, in 2017, 1.3 percent of the children born in 2015 were completely unvaccinated. That’s up from the 0.9 percent seen in an earlier similar assessment of the kids born in 2011. A 2001 survey with a different methodology suggested the proportion was in the neighborhood of 0.3 percent.

Young children are especially vulnerable to complications from vaccine-preventable diseases, some of which can be fatal.
