A new study finds children are less likely to get the chicken pox if they get two doses of the vaccine instead of just one.

In 2006 the CDC recommended a second dose of the vaccine.

Routine vaccination began 15 years ago, but experts decided one dose didn't offer enough protection or eventually wore off.

Authors of the latest study in journal of infectious disease discovered that one dose protected 86 percent of children, while two vaccines were 98 percent effective.

It should be noted two of the study's authors have financial times to the company that sells the vaccine.
