2014/2015 Influenza Vaccine Effectiveness

• The best way to prevent the flu is the influenza vaccine.

• The best way to lessen complications of the flu is antiviral medication.

• The best way to prevent the spread of flu is to stay home when ill.

All three strains currently circulating are covered by this year`s vaccine - A(H3N2), A(H1N1) and B.

• Some of the A(H3N2) viruses circulating nationally and in Iowa are a drifted strain.

• Although the drifted strain is not an exact match, the vaccine should provide partial protection.

Vaccination is still the best defense against the flu. IDPH and the CDC recommend all Iowans older than age 6 months receive the vaccine.

• Even if you have already had one strain of the flu, you can still get sick with the other two strains of the flu circulating in Iowa so vaccination would still be recommended.

• It is not too late to be vaccinated. The flu season typically peaks in February and can last until May.

Seasons in which A(H3N2) viruses dominate tend to be more severe, with more hospitalizations and more deaths.

• • Those at highest risk of developing serious complications of the flu include the very young, very old, pregnant women and those with chronic conditions such as heart or lung disease. Beginning antiviral medications early for these individuals is particularly important.

    Antiviral medications are not a substitute for vaccination, but are an important second line of defense to treat the flu.

    • • Most effective if started as soon as possible and within 48 hours of the beginning of flu symptoms. (If those with serious illness, those who are hospitalized or those at high risk of complications do not seek medical attention within 48 hours, starting antiviral medications is still recommended.)

      • Call your doctor right away if you develop symptoms of the flu.

      • Antiviral medications make influenza illness milder, shorter, and reduce the risk of ending up in hospital or dying from influenza.

      • Receiving antiviral medications quickly is especially important for those at risk of complications.

     

    The flu is a respiratory illness caused by viruses. The flu comes on suddenly and symptoms may include fever, headache, tiredness, cough, sore throat, nasal congestion, and body aches. Illness typically lasts two to seven days. Influenza may cause severe illness or even death.
