Avaxim

Avaxim is an inactivated Hepatitis A vaccine that helps protect against infection caused by the Hepatitis A virus (HAV), which affects the liver and can lead to acute illness. It works by stimulating the body’s immune system to produce antibodies against HAV, offering protection for several years after full vaccination. It is recommended for children, adults, and individuals at risk of exposure to contaminated food, water, or close contact with infected persons.
