1 SWINE FLU SHOT MAY BE ENOUGH

New York Times

A single shot of swine flu vaccine appears to protect most children and teenagers nearly as well as it protects adults, federal health officials said Monday.

However, young children who have never had the flu or a flu shot need two doses, they said. To fully protect them against both swine and seasonal flu this year, those children will need four shots.

Preliminary results of the next round of trials, in pregnant women, are expected early next month.

The latest trials, done in about 600 children and teenagers, ages 10 to 17, found that they received a "robust immune response" from a single dose, said Dr. Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases.

Children from 6 months to 9 years old received some protection from one shot but not enough, so health officials will recommend that they get two shots 21 days apart.

Doctors can give both the swine and seasonal flu shots in a single visit and then the two together again 21 days later, said Dr. Anne Schuchat, director of the flu division of the Centers for Disease Control and Protection.
