Hepatitis A immunity statement as per material?

The statement reflects how immunity to Hepatitis A is acquired and persists. After exposure to Hepatitis A and recovery from the infection, the body develops anti-HAV antibodies that remain for life, giving lifelong protection against future infections. This is why natural infection typically results in durable immunity. Hepatitis A is an acute, self-limiting illness and does not usually cause chronic liver disease. Vaccination can also confer protection, though the standard schedule generally involves more than a single dose to ensure long-term immunity. In contrast, Hepatitis A is transmitted primarily via the fecal-oral route through contaminated food or water, not only by needle sharing.
