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. Equity-indexed annuities are distinguished by the interest yield return being partially based on an equities index, such as the S&P 500 index.
In its most general sense, an annuity is an agreement for one person or organization to pay another a stream or series of payments.Usually the term âannuityâ relates to a contract between you and a life insurance company, but a charity or a trust can take the place of the insurance company.There are many categories of annuities. They can be classified by: 1  Nature of the underlying investment â fixed or variable. Protection from creditors. 2  If you own an immediate annuity (that is, you are receiving money from an insurance company), generally the most that creditors can access is the payments as theyâre made, since the money you gave the insurance company now belongs to the company.
