In a blow to the federal plan to fight bird flu, at least six U.S. states are planning to buy fewer antiviral drugs than they have been offered by the federal government, and at least 16 more are undecided as to how much Tamiflu and Relenza they will buy.
Questions About Cost and Effectiveness
The proposed plan was that the federal government buy 44 million of an estimated 75 million doses of Tamiflu and Relenza, with states buying the balance. But many states are concerned about both the cost and effectiveness of the drugs.
Arizona only plans to buy an eighth of its allotment, so as not to drain funds needed to prepare hospitals. Colorado plans to only buy 5,400 courses out of the more than 477,000 it has been offered, until there is more evidence that the drugs will actually work against bird flu.
Flu Shots Ineffective for the Elderly
In related news, two new studies have shown that flu shots provide at most modest protection against the flu for those over 65. A review of 71 previous studies found that flu shots prevent just 25 percent of flu-like illnesses, hospital admissions and flu-related deaths among the elderly. Among elderly people living in nursing homes and long-term care facilities, the vaccines prevented 45 percent of these conditions.
A second review also found that flu shots given to staff at nursing homes do not decrease cases of flu or lower respiratory tract infections among the patients.
Other Reasons for the Statistics
Statistics show that those who receive a flu shot are among the least likely to die from any cause in a given year, but this could be a result of the fact that those who get flu shots are also more likely to have higher incomes and better health care to begin with.
