Grand Junction, Colo. (KKCO) --- District 51 schools have seen a slight decrease in the number of students that get immunized before school starts.
Between the 2011-2012 and 2012-2013 school year, almost 200 elementary school students and 100 sixth graders did not get their required shots.
When entering kindergarten, students are required to get DTAP, Polio, MMR and Varicella vaccines and when entering sixth grade, students should get the TDAP vaccine.
Parents are allowed to exempt their children from immunizations due to personal, medical or religious reasons.
Bryan Sanford is a father of four and said he opted out of getting his kids immunized because of what the long term effects of these drugs could be. He has chosen natural remedies for his children, which he said has worked thus far.
School officials however encourage parents to get their children immunized as it can prevent the spread of diseases among students.
The Mesa County Health Department has an immunization clinic and is open to residents who want to keep their children's shots up to date.
