If you are unsure about which vaccinations they have received, talk to your health care provider to get their vaccination schedule on track.  If your child has special medical conditions or other high risk factors, they may need additional vaccines. Talk to your health care provider about other recommended vaccines.  After 6 months of age, they should also get the flu vaccine every fall.

Please refer to:

When you contact your healthcare provider to request either the Meningococcal, HPV, or Hepatitis B vaccine, they will order it directly from the Health Unit specifying the name of the patient they are ordering it for. You do not need to make another appointment at the catch-up clinic, please attend the appointment you have made with your healthcare provider. Any appointment made at the catch-up clinic will be cancelled if we have a record of your Healthcare Provider ordering the vaccine for your child.

Parent(s)/legal guardian(s) are responsible for updating the Windsor-Essex County Health Unit (WECHU) every time their child receives immunizations from their healthcare provider. The healthcare provider is not required to send this information to the Health Unit.
