Despite many children receiving their vaccination routine in time, there is a concern among health officials as they have noticed a decline in measles vaccinations.

A study was of vaccination rates for children ages 19 through 35 months was conducted by the Centers for Disease Control and Prevention and it released the results on Thursday.

It was observed during a survey that was conducted in 2009 of about parents of more than 17,000 children, most routine vaccines were received by more than 90 per cent of the children and at least one was received by more than
99 per cent.

According to the study, there was a dip from 92 per cent in 2008 to 90 per cent in the immunization rate for the measles-mumps-rubella vaccine. And this is what the officials are worrying about seeing the recent rise in cases of measles.

There was a slight decline in the number of children getting vaccinated against whooping cough but health officials feel that to control the attack of the recent whooping cough it was important to vaccinate adults, teens and everyone who handle children.
