The influenza virus has many different strains. It is the cause of many upper respiratory infections ranging from mild colds to severe, complicated pneumonia. Documented cases in the U.S. usually begin mid-October and extend through mid-April. Symptoms may include:  fever, cough, headache, and muscle aches.

Children have a higher rate of infection than adults, probably related to their developing immune systems. Since the flu virus can lead to significant illnesses, researchers have developed a vaccine that aids in the prevention. As viral strains differ each year, vaccine reformulation also changes. Therefore, everyone is recommended to be vaccinated on a yearly basis.

Quadrivalent Influenza Vaccine:

As an inactive (killed) vaccine, it will not cause fever or infection.

Recommended for everyone older than 6 months old.

Patients younger than 9 years and first-time flu vaccine need a second booster at least 1 month later.

Those with egg allergies should be vaccinated in the presence of a healthcare provider who can manage the rare, severe allergy.

Though not 100% effective, the symptoms will probably be milder in those that come down with the infection.

Anti-viral medications are only recommended for children with:


heart disease

kidney disease

blood disorders

compromised immune systems
