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.
Refined grains go through a milling process that removes the bran and the germ, which eliminates most nutrients. Examples of whole grains include: 1  Whole wheat and whole wheat berries, whole wheat bulgur, whole wheat couscous, and spelt. 2  Brown rice. 3  Corn, whole cornmeal, polenta, and popcorn. 4  Oat groats, steel-cut oats, rolled oats. 5  Whole rye.
