      More women opting for preventive mastectomy - but should they be?

      Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

A Food and Drug Administration committee, meeting Wednesday by teleconference, reached a final decision on the components of the next vaccine.

The flu vaccine is reformulated every year to try to match the strains that specialists predict are most likely to strike. A decision has to be made months in advance so manufacturers have time to make the vaccine.

The decision made by the FDA committee matches the formula adopted for next year by the World Health Organization. The vaccine includes two strains of A-type flu and one of B-type. Type A flu is generally the harshest.

The vaccine for next flu season will change one of the Type A components to A-Fujian. That’s the strain that was most troublesome this year and for which the current vaccine offered little protection.

The second A strain will remain the same, A-New Caledonia.

In addition, the B strain in the vaccine will change from B-Hong Kong to B-Shanghai next year.
