PORTLAND — As part of eight planned influenza clinics, the city of Portland is offering two walk-in sessions next week for adults 18 or older.

The clinics will be held from 1 to 4 p.m. Monday at St. Pius X Parish Hall, 492 Ocean Ave., and from 11 a.m. to 3 p.m. Wednesday in the State of Maine Room in City Hall on Congress Street. Vaccines are $10 or free for those with a Medicare Part B card. All types of insurance, including MaineCare will be accepted.

Immunization is important for groups at high risk of seasonal influenza, including those over the age of 50, people with chronic medical conditions, such as diabetes, asthma, heart disease or immune system problems, pregnant women, people in long-term care or institutional settings, health care workers, caregivers and household contacts of those at high risk and children age 6 months and older.

Pneumococcal pneumonia vaccines will also be available for $45 or free for people with MaineCare.
