What are inactivated vaccines?

Inactivated vaccines are vaccines that contain killed or inactivated forms of the pathogen, providing immunity without causing the disease.

How do inactivated vaccines work?

Inactivated vaccines work by introducing the inactivated pathogen into the body, triggering an immune response. The immune system recognizes the pathogen as foreign and produces antibodies to fight it. This creates a memory of the pathogen, allowing the immune system to quickly respond if the person is exposed to the live pathogen in the future.

Benefits of inactivated vaccines

Some of the benefits of inactivated vaccines include:

• Safety: Since inactivated vaccines do not contain live pathogens, they cannot cause the disease they are designed to prevent.
• Effective immunity: Inactivated vaccines can provide long-lasting immunity against the targeted pathogen.
• Stability: Inactivated vaccines are usually more stable and have longer shelf lives compared to live vaccines.

Examples of inactivated vaccines

Some examples of inactivated vaccines include:

• Polio vaccine
• Hepatitis A vaccine
• Rabies vaccine

Immunization with inactivated vaccines plays a vital role in preventing the spread of infectious diseases and protecting public health.
