PANAMA CITY- Health officials are observing the 20th annual national infant immunization week this week.
They say infant immunization week came about because of conflicting information.
"Unfortunately with all the information out there, a lot of people have made up their blogs, they have their own opinion and research isn't quite accurate," said Lisa Callahan, Florida department of health in bay county nurse.
The problems seemed to start his 1963, with the introduction of a measles vaccine
Some parents refused to vaccinate their children.
Before 1963, measles infected about 500-thousand Americans a year.
So far this year, the centers for disease control have received reports of 129 measles cases in 13 states.
That's the most in the first four months of any year since 1996.
Most cases come from overseas.
"if you are traveling overseas where these vaccines are not provided, if you're not vaccinated then it can infect your child or even you and cause in outbreak and whoever has not been vaccinated," said Callahan.
In the last 12 months, bay county health department officials have vaccinated 2,157, age 2 and under against a variety of diseases.
Some parents blame vaccinations for the increase in autism cases.
But there is no scientific proof of that link.
"Currently the we has the safest vaccines according to the CDC and all research that we read that our vaccines are safe," said Callahan.
The bay county health department administers immunizations Monday through Friday, 7:30 to 4:30.
They are free to minors with parental consent.
