More American kids are getting their shots than ever before -- the CDC reports.

But poor kids, and those in a few states and cities, are lagging behind.

The CDC released its annual report on nationwide vaccination rates for toddlers.

In short: the US has reached record immunization levels and has met, or is close to meeting, national goals.

Nine out of ten toddlers have been vaccinated against every disease recommended for their age.

With one exception, the DTP vaccine, for diphtheria, tetanus and whooping cough, is slightly below the national goal of 90 percent.

Millions of Americans with chronic illnesses are not getting the medications and treatments they need because they don't have insurance.

A new report published in the Annuals of Internal Medicine finds about one in every three uninsured working age adults have been diagnosed with a chronic illness, like high blood pressure or diabetes.

Many of these people aren't going to the doctor regularly or taking the medications they need, and could be putting their health at risk.
