There will always be a debate regarding children and immunizations.
"I knew that I didn't want my children to have a whole bunch of shots at once," said Allison Mack.
Mack is a mother of two and owner of Austin Moms Blog. Her boys, Townsend and Lincoln, are both on delayed vaccination schedules.
Mack said, "The vaccination is still important to me, but, the schedule that's recommended by the pediatrician is very aggressive and seems to be a bit too much."
"If the parent makes sure the child stays on schedule, then that will mean that they will stay in school longer, they will be healthier and live more productive lives as they're growing up," said Marcus Cooper, with the Williamson County and Cities Health District. "In our population, in Williamson County, there are 13 deaths for every 100,000 people and those deaths were related to illnesses that could have been prevented."
This year marks the 20th anniversary of National Infant Immunization Week. Health officials are encouraging parents to immunize.
Marcus said, "Chicken pox, measles, mumps, all of those illnesses can be covered if you keep your child on schedule."
"The first round of shots we did, we did not do a delayed start and I noticed that she was having a bad reaction to it," said Christina Lee.
Lee says that's when she decided to put baby Nora on a delayed vaccination schedule.
"We just did two at a time and came back a month later, versus doing it all at once," said Lee.
Christina's expecting another girl in a few weeks. She says what's best for the majority, is not what is best for her kids.
"Each one of these vaccines has a risk with it," added Lee.
Marcus said, "We respect people's decisions, but this is information that is from the national, state and local level, supporting it."
"I wish that the encouragement was to research...versus just saying you need to get your vaccines," Lee said.
