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.
Why get vaccinated? HPV vaccine is an inactivated (not live) vaccine which protects against four major types of HPV. These include two types that cause about 70% of cervical cancer and two types that cause about 90% of genital warts. HPV vaccine can prevent most genital warts and most cases of cervical cancer. Protection from HPV vaccine is expected to be long-lasting. But vaccinated women still need cervical cancer screening because the vaccine does not protect against all HPV types that cause cervical cancer.
