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.

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.
Vaccination is the best way to prevent chickenpox. A chickenpox vaccine has been available in the U.S. since 1995 and is easy to get from a doctor or a public health clinic.The chickenpox vaccine is very effective at preventing the disease -- between 70% and 90% of people who get vaccinated will be completely immune to chickenpox.wo doses of the vaccine should be given at least four weeks apart. If you've never had chickenpox or been vaccinated and you are exposed to chickenpox, being vaccinated right away will greatly reduce your risk of getting sick.
