Summer may be in full swing but preparations for flu season are already underway.

Drug manufacturer Sanofi Pasteur of Monroe County has started to ship this season's flu vaccine.

Sanofi says it will distribute more than 60 million doses of the vaccine.

A new addition to their lineup is a vaccine covering four strains of influenza.

The vaccines from past years have only covered three strains.

Flu vaccines will be available to the public next month.
