Most vaccine-preventable diseases are caused by germs that are called "viruses" or "bacteria." Vaccines help your body recognize and fight these germs and protect you each time you come in contact with someone who is sick with any of these diseases.

Health Department provides the following services to the community:

  • Immunization information for parents, area schools, day care centers, private provider offices, and the general public
  • Free childhood vaccinations to eligible children through the Center for Disease Control Vaccines For Children's (VFC) program
  • Community outreach clinics to immunize groups at risk for vaccine preventable diseases

Immunizations appointments are available in our Mayville office.  Please call 716-753-4491 for an appointment.  Walk-ins accommodated whenever possible.

Childhood Immunization Schedule

Adult Immunization Schedule


Because of vaccines, some diseases (like polio and diphtheria) are becoming rare in the U.S. Vaccination can prevent certain deadly diseases in infants, children, teens, adults and travelers of all ages.  Like any medication, vaccines can cause side effects. For the most part these are minor (for example, a sore arm or low-grade fever) and go away within a few days.  Vaccines are continually monitored for safety.  A decision not to immunize a child also involves risk and could put the child and others who come into contact with him or her at risk of contracting a potentially deadly disease.   

Why Vaccinate?

  • Vaccination is a highly effective, easy way to keep your family healthy.
  • On-time vaccination throughout childhood is essential because it helps provide immunity before children are exposed to potentially life-threatening diseases.
  • Vaccines are tested to ensure that they are safe and effective for children to receive at the recommended ages.

Seasonal Flu or Influenza:

The flu is not just a really bad cold. The flu is a contagious illness that affects the nose, throat, lungs, and other parts of the body. It can spread quickly from one person to another. Anyone can get the flu and serious complications from the flu can happen at any age. It can cause mild to severe illness, and at times can lead to death.

The best way to prevent the flu is by getting a flu vaccine. Everyone 6 months or older should get a flu vaccine every year.

You can't get the flu from getting the flu vaccine.  The flu vaccine does not give you the flu.  It stimulates your body to produce antibodies.  These antibodies protect you from flu viruses.  Once you get the flu vaccine, it takes about two weeks for it to be fully effective.  You should not wait to get vaccinated.

COVID-19 is a respiratory disease caused by SARS-CoV-2, a coronavirus discovered in 2019. The virus spreads mainly from person to person through respiratory droplets produced when an infected person coughs, sneezes, or talks. Some people who are infected may not have symptoms. For people who have symptoms, illness can range from mild to severe. Adults 65 years and older and people of any age with underlying medical conditions are at higher risk for severe illness.  People should get COVID-19 vaccines and boosters to prevent getting and spreading the illness.
