"However, [the flu shot] can still be beneficial and vaccination should continue to be offered throughout the flu season, even into January or later", the CDC says in a flu shot advisory. Until scientists create something more effective, the flu shot is still the best way to protect yourself and your family from flu and any associated illness. For the last couple of years this spray mist was not recommended by the CDC's Advisory Committee on Immunization Practices because of its lack of efficacy against the circulating strains of the virus.

A newly-available flu vaccine this winter could prevent 700 deaths, over 2,000 hospitalisations and 30,000 GP consultations in those aged 65 and over in England.

The Washington Post reported in February on the 36-percent success rate and said it dropped to 25 percent in the USA against the "most virulent and predominant strain" known as H3N2. Patients were included if they were at least 1-year-old and had seen a doctor within seven days of the onset of flu-like symptoms.

Myth #7 - I have to have a fever to actually have the flu and be contagious.

"The CDC wants to vaccinate as many people as possible, so they're saying, 'Hey if the science holds out and more people get this one then it's back to the win-win, '" Christensen continued.

While a flu shot does not make a person completely immune to the flu, a seasonal flu vaccine is the "best way to reduce your risk of getting sick with seasonal flu and spreading it to others", the CDC said. "It should be widely available soon".
