Live Vector Vaccine

A Live Vector Vaccine is a type of vaccine that uses a harmless virus or bacteria to introduce a piece of pathogen's DNA to cells of the body. The cells then produce a protein that triggers an immune response. This type of vaccine is used to prevent infectious diseases.

Mechanism of Action[edit | edit source]

Live vector vaccines work by using a harmless virus or bacteria, known as a vector, to deliver a piece of the pathogen's DNA to the cells of the body. The cells then use this DNA to produce a protein that is unique to the pathogen. This protein triggers an immune response, which includes the production of antibodies. These antibodies are then able to recognize and attack the pathogen if the individual is exposed to it in the future.

Types of Live Vector Vaccines[edit | edit source]

There are several types of live vector vaccines, including viral vector vaccines and bacterial vector vaccines. Viral vector vaccines use a harmless virus to deliver the pathogen's DNA. Examples of viral vector vaccines include the adenovirus vaccine and the vesicular stomatitis virus (VSV) vaccine. Bacterial vector vaccines use a harmless bacteria to deliver the pathogen's DNA. An example of a bacterial vector vaccine is the BCG vaccine.

Advantages and Disadvantages[edit | edit source]

Live vector vaccines have several advantages. They are able to stimulate a strong immune response, and they can be used to vaccinate against multiple diseases at once. However, they also have some disadvantages. They can cause side effects, and they may not be safe for people with weakened immune systems.
