Michigan State University Professor of Pediatrics Doctor Gerard Breitzer says its an issue that causes many parents much worry: Flu vaccinations.
"Mostly they're concerned about the safety. Will I get sick? Will my child get sick?" he says.
Now he hopes a new study published in the Journal of American Medicine will ease their concerns. It's the most extensive study on the safety of the flu vaccine of all time, and it confirms the vaccine is safe for babies and toddlers. Researchers studied 45 thousand vaccinated children and found just 13 cases of mild nausea and diarrhea.
The Center for Disease Control recommends all young children between six months and five years old get vaccinated. It estimates more than 90 children under the age of five die each year because of the flu.
