ST. PAUL (AP) - Health officials in Minnesota say this season's flu vaccine will be stronger than last year.

Vaccine shipments are beginning to arrive at some of the state's health clinics. Joe Kurland, a vaccine specialist at Children's Hospitals and Clinics of Minnesota, says the formulation for this year has been updated to include protection against a new flu strain and it should a good match for what residents will be up against.

But some health professionals are concerned that less people will seek flu shots due to problems with a less effective vaccine last year.

More than 4,300 people were hospitalized and 10 children died last flu season in Minnesota.
