Neuraminidase inhibitors are effective against all variants that have caused disease in humans, including the virus of the 1918 pandemic (Tumpey 2005). In human H5N1 influenza, treatment with an oral neuraminidase inhibitor, oseltamivir, seems to be effective in some cases, but may fail in others.
A: An equity-indexed annuity is an alternative investment to a traditional fixed rate or variable rate annuity, and it may be appealing to moderately conservative investors.

A mortgage payment is a regularly occurring series of payments, or annuity, on a real estate loan. These people aren't on the receiving end of the annuity - the bank is. Some other examples of annuities include life insurance payments, pension payments, regular savings account deposits, and some investments.
