A new study suggests babies and young kids get significantly more protection from the spray version of the flu vaccine than from shots.
Researchers say they found the spray vaccine was 55-percent more effective in protecting children under the age of five.
However, there is one drawback.
The study showed a few of the youngest patients who received the spray had an episode of asthma-like wheezing in the weeks after their first dose.
The findings are from one of the largest comparisons of flu inoculations of its kind.
The results are being presented at a child-health meeting, today.
The research was funded by the makers of the FluMist nasal spray.
Right now, the spray is sold only for children five and older but the manufacturers are seeking government approval to change that.
