Flu Vaccine Update

By: Corinne R Replogle, MD

In the US, flu epidemics typically occur during late Fall through early Spring, with the rates of infection being highest among children.  The rates of serious illness and death are higher for children less than two, adults 65 years or older, or people with medical conditions that make them more vulnerable.   The flu resulted in an estimated 36,000 deaths per year during the years 1990-99.  

2011 Recommended Adult Immunization Schedule

The 2011 Recommended Adult Immunization Schedule by the CDC has been revised to reflect a recommendation for vaccination of all persons aged 6 months and older, including all adults. This is a change from before when the recommendation for adults was if they were immunocompromised or 50 years or older.  Routine influenza vaccination is also recommended for all women who are or will be pregnant (in any trimester) during influenza season, which in the United States is usually early October through late March .  This is also a change from previous recommendations of only immunizing women who would be in the 2nd or 3rd trimester during the flu season.

Flu Shot or Flu Mist?

The flu shot vaccine can be used for any person aged ≥6 months, including those with high-risk conditions. The nasal flu mist vaccine may be used for healthy non-pregnant persons aged 2-49 years. No preference is indicated for the flu shot or flu mist when considering vaccination of healthy non-pregnant persons aged 2-49 years.  The safety or effectiveness of the flu mist has not been established in persons with underlying medical conditions which could lead to complications. So these people should get the flu shot. The Core Physicians’ offices currently have a limited supply of the nasal flu mist.

What if I get the Flu?

There are antiviral medications to the flu, but they only decrease the disease by about 50% and shorten the duration by about a day.   Also, it only makes a difference if given within the first 48 hrs of symptoms. So getting in early to see your doctor is important.  It’s hard to know if you have the actual influenza or a regular cold.  But high fever, severe muscle aches are more common with the flu than regular colds.

The best advice I give my patients is to get the flu shot and take everyday precautions to stop the spread of germs.
