Inactivated Hepatitis A Vaccine

Introduction

The Inactivated Hepatitis A Vaccine is a preventive vaccine that protects against Hepatitis A virus (HAV), a contagious liver infection. It contains an inactivated (killed) version of the virus that stimulates the immune system to build protection without causing illness. Recommended for both children and adults, especially those traveling to endemic areas, this vaccine is a safe and effective way to prevent serious liver damage caused by the Hepatitis A virus. It is usually given as a two-dose schedule for long-lasting protection.
