The most recent epidemiologic data from the Center for Disease Control states that this year’s flu shots reduced a patients chance of catching the flu by 48% compared to no vaccine at all. The party line is that those individuals who were vaccinated and still contract Influenza A or B get a milder version. In this week’s Morbidity and Mortality Weekly Report, Brandon Flannery, PhD, of the CDC and associates believe the flu vaccine is about 43% effective against influenza A and 73% versus Influenza B. Most flu infections this season have been caused by Influenza A (H3N2). This particular virus has the ability to change its genetic composition frequently thus making updates to vaccines necessary more frequently than current manufacturing methods can accommodate.
We are heading into the peak weeks of Influenza A infection in Palm Beach County, Florida. Individuals with flu and upper respiratory tract infection type symptoms should see their doctor. An Influenza Nasal swab test can determine if you have the flu. It takes about fifteen minutes to learn the test result after obtaining a nasal swab. If you have the flu we can place you on a dose of Tamiflu to cut the duration and symptom spectrum of the infection. We can also recommend a ten day course for family members and intimate partners as an effective prevention against the disease. Call the office if you have any questions.
