Local vaccine developer Sanofi Pasteur (Swiftwater, Pennsylvania) has developed a new delivery system just in time for the 2011-2012 flu system. While previous flu shots were administered by a needle that is 1 to 1.5 inches in length, the Fluzone Intradermal vaccine features an ultra-fine need that is 90 percent shorter (only 0.06 inches in length). Instead of being injected into the muscle, the vaccine is injected into the dermis, or inner layer of skin. This should provide a big improvement in comfort.
The new system is indicated for adults aged 18 through 64. The regular flu shot will continue to be available for others, as will the nasal spray vaccine for non-pregnant, healthy people ages 2 to 49. Check with your doctor, clinic or pharmacist to see if Fluzone Intradermal is available in your community.
