Attenuated Vaccines

Attenuated vaccines are a form of immunization created by weakening a virus or bacteria in a laboratory to reduce its ability to cause disease. These weakened viruses or bacteria are called attenuated pathogens. Attenuated vaccines can provide long-lasting immunity against diseases by activating key parts of the immune system. These vaccines are often used to protect against serious childhood illnesses such as measles, mumps and rubella. They can also be used to protect against some forms of cancer, such as the HPV vaccine. Attenuated vaccines are an important tool in the fight against infectious diseases and offer a safe and effective way to protect against disease.
