Hepatitis A Inactivated Vaccine: What You Need to Know

Hepatitis A vaccines are primarily divided into two types: inactivated vaccines and live attenuated vaccines. The inactivated Hepatitis A vaccine is made by completely neutralizing the Hepatitis A virus, which eliminates its ability to cause infection while still triggering the body's immune system to produce protective antibodies.

How Does the Inactivated Hepatitis A Vaccine Work?

Once administered, the inactivated vaccine introduces a non-infectious form of the Hepatitis A virus into the body. Although it cannot replicate or cause illness, it is still recognized by the immune system, which responds by creating a defense mechanism in the form of antibodies. This helps protect individuals from future exposure to the live virus.

Who Should Receive the Hepatitis A Inactivated Vaccine?

This vaccine is recommended for a wide range of individuals, including children, healthcare workers, food industry employees, and anyone whose occupation involves potential contact with the Hepatitis A virus. Children can receive their first dose at one year of age, and there is no upper age limit for adults seeking vaccination.

Global Use and Benefits

The inactivated Hepatitis A vaccine is widely used across many countries and is considered a safe and effective method of disease prevention. It plays a crucial role in controlling the spread of Hepatitis A, especially in areas with high risk of exposure or limited access to clean water and sanitation.
