FLU VACCINE CLINICS 2026: 

• Please check back for more information

Provided at no out-of-pocket charge to Hamilton residents, flu clinics. The Division recommends that all residents aged 6-months and older get an annual flu shot. The Division's 55+ clinics are targeted at our high-risk population including senior citizens, the chronically ill, and individuals with special needs. We recommend that you consult with your physician if you have any questions as to whether you should receive this immunization.

Note: The current seasonal influenza vaccine is required every year for children 6 months through 59 months of age in order to attend daycare/pre-school after January 1.

In addition to adults, children over the age of 9 may also attend these clinics but must be accompanied by a parent or legal guardian.

Pneumonia vaccines will be offered to residents ages 65+ at all township flu clinics, or by appointment. To make an appointment call 609-890-3884 or 609-586-0311.

If getting both the flu and pneumonia vaccine during the same visit, the shots must be given in different arms. If there is a reason that the resident cannot receive a shot in both arms at the same time, then the flu shot only will be given and they will be asked to come back in two weeks to receive the pneumonia shot in that arm.

Please note that you may print, complete, and bring with you the Flu Vaccine Registration and Consent Form (PDF) to save time.

The clinics are open to Township residents only. Proof of residency is required. In addition to all adults, children over the age of 9 may also attend these clinics, but must be accompanied by parent or legal guardian.
