Attenuated Vaccine

Attenuated vaccines are live, weakened versions of a disease-causing organism. They stimulate the body to produce immunity against a particular disease by stimulating the body’s immune system to recognize and fight the weakened organism. Attenuated vaccines are highly effective, safe and cost-effective compared to other types of vaccines and provide long-term protection against the disease. They are used to immunize against a variety of diseases, such as polio, measles, rubella, chickenpox and influenza, and are especially important in areas where access to other vaccines is limited. Attenuated vaccines can also be used to treat certain diseases, such as HIV and hepatitis C.
