It catalyzes the esterification of the hydroxyl group of lipoprotein cholesterol by the transfer of a fatty acid from the C-2 position of lecithin. In familial lecithin:cholesterol acyltransferase deficiency disease, the absence of the enzyme results in an excess of unesterified cholesterol in plasma. EC 2.3.1.43.
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.lthough the virus in the chickenpox vaccine is generally incapable of causing a disease, it still stimulates a response from the body's immune system. That response is what gives someone who's had a shot for chickenpox immunity or protection from the illness.
The chickenpox vaccine is given to young children in two doses, the first between 12-15 months and a booster shot between 4-6 years. Children 13 and older who've never had chickenpox or been vaccinated should get two doses at least 28 days apart. The chickenpox vaccine can be given at the same time as other vaccines. It is also available as part of the measles-mumps-rubella vaccine, in a combination shot called MMRV.
