Inactivated Vaccines

Inactivated vaccines are made using viruses or bacteria that have been killed or inactivated so they can’t cause disease. These vaccines trigger an immune response, helping the body recognize and fight off the actual pathogens if encountered in the future. Common examples include the polio vaccine and the hepatitis A vaccine. Since they do not contain live microbes, they are generally safe for people with weakened immune systems. However, they may require multiple doses to ensure effective immunity.
