Inactivated virus vaccines

Inactivated virus vaccines are made from viruses that have been killed or inactivated so they can’t cause disease. These vaccines stimulate the immune system to recognize and fight the actual virus without risking infection. When vaccinated, the body learns to recognize and combat the virus if it encounters it in the future. Common examples include vaccines for polio and hepatitis A. These vaccines are generally safe and effective, providing protection against serious illnesses caused by the viruses they target.
