If a half-dose flu shot were available to you at a reduced cost, would you take it?
Half-dose flu shots are effective in adults, especially in women and those younger than 50, and offer a viable way to stretch supplies during vaccine shortages, a government study found.
The strategy also might be an option during hard economic times since lower doses likely would mean cheaper shots, said Vanderbilt University vaccine expert Dr. Kathryn Edwards, who wasn't involved in the study. And the lower dosage could open doors to vaccinating people in poor countries where flu shots are little used, she said.
