Who should not be vaccinated?

Some people should not be vaccinated without first consulting a physician. They include:

  • People who have a severe allergy to chicken eggs.
  • People who have had a severe reaction to an influenza vaccination in the past.
  • People with an allergy to Thimerosol.
  • People who developed Guillain-Barre syndrome (GBS) within 6 weeks of getting an influenza vaccine previously.
  • Children less than 6 months of age (influenza vaccine is not approved for use in this age group).
  • People who have a moderate or severe illness with a fever should wait to get vaccinated until their symptoms lessen.


The single best way to prevent the flu is to get vaccinated each fall, but good health habits can also help protect against the flu. To decrease the risk of getting sick this flu season:

  • Wash your hands! Over 20 infectious agents, including the flu, can be avoided by properly washing your hands.
  • Avoid close contact with those that are sick.
  • Stay at home when you are sick to avoid spreading infection to others.
  • Cover your mouth and nose with a tissue. If a tissue is not available, cough or sneeze into your elbow to avoid contaminating your hands.
  • Avoid touching your eyes, nose, or mouth.

Collin County Surveillance

Each year data concerning the number of flu cases being seen in schools and physician offices is collected. Nasal swabs may be used to further investigate areas that are hardest hit by influenza-like illness. Early, mid, and late season specimens are examined. All of these surveillance activities help identify the changes that naturally occur among circulating influenza viruses.
