The chickenpox vaccine is a shot that can protect nearly anyone who receives the vaccine from catching chickenpox. It's also called the varicella vaccine, because chickenpox is caused by the varicella-zoster virus. The vaccine is made from a live but weakened, or attenuated, virus. Viruses that have been attenuated are less virulent than viruses that are not.
The term whole grain refers to a variety of grains, including wheat, corn, rice, oats and rye, which are still in their natural form. Whole grains have a bran, germ and endosperm. To be considered a whole grain, the entire grain must still be intact and not just the endosperm, as is the case in refined grains.
A whole grain is the entire grainâwhich includes the bran, germ and endosperm (starchy part). The most popular grain in the US is wheat so that will be our example. To make 100% whole wheat flour, the entire wheat grain is ground up. Refined flours like white and enriched wheat flour include only part of the grain â the starchy part, and are not whole grain. They are missing many of the nutrients found in whole wheat flour.
