Health departments across southwestern Connecticut spent Thursday preparing for a massive effort to get as many people as possible vaccinated against influenza.

The Norwalk Health Department is one of at least eight health agencies in the area that had set up clinics inside local train stations, where commuters and residents can get flu shots.

The price of vaccinations ranges from $20 to $35, depending on the location of the clinic.

Dr. Marian Evans, of the Bridgeport Health Department, says that research studies produced by the Center for Disease Control show that a drop in productivity caused by the flu should convince people to come out and get vaccinated.

Health officials are encouraging everyone to get vaccinated this year, not only those at risk. They're hoping the regional flu clinic along the New Haven line will help them reach the masses.
