Flu killed and sent more people in the United States to the hospital last winter than any other season in recent history, according to new data released Thursday.
And in Minnesota, more than 6,400 people were hospitalized and five children died from influenza or related complications last year.
Those stark numbers underscore how severe the flu can be and come with a warning from state public health officials who say that not enough children are being vaccinated.
"Since children can't make the decision to get vaccinated themselves, it's up to parents and health care providers to make it happen," Kris Ehresmann, director of the Minnesota Department of Health's infectious disease division, said in a prepared statement.
About 62 percent of Minnesota children between the ages of 6 months and 17 years received vaccinations during the 2017-18 influenza season, which is an increase from previous years, according to a news release announcing the Centers for Disease Control and Prevention data.
Minnesota's rate was slightly higher than the national overall vaccination rate of 57.9 percent.
But that's not enough, health officials say.
Of the 172 children across the country who died last year, 74 percent were not vaccinated, according to the CDC.
