Cost considerations	Vaccine cost varies; often charged in INR; coverage varies by program	HBV vaccine costs vary; coverage subject to policy terms and waiting periods

What is Hepatitis A?

Hepatitis A is an acute viral liver infection caused by the hepatitis A virus. It is typically transmitted via the fecal-oral route, often through contaminated food or water, and does not usually lead to chronic liver disease in people with normal immune systems.

Most cases are mild in children and can be more uncomfortable for adults, sometimes requiring medical care. Prevention hinges on vaccination, safe food handling, and good sanitation; maintaining hand hygiene reduces spread in households and public spaces.

• Vaccination programs promote community protection
• Hepatitis A prevention supports sanitation improvements
• Vaccine-induced immunity is typically durable
• Vaccination reduces hospital visits during outbreaks
• Travelers benefit from protection against HAV
• Children often experience milder disease when vaccinated
• Public health clinics frequently offer HAV vaccines
• Vaccine responses are generally well tolerated
• Prevention lowers work and school disruption due to illness
• HAV vaccination can be integrated with routine immunizations
• Vaccination aligns with broader hygiene and sanitation goals

• Post-exposure prophylaxis is time-sensitive in some outbreaks
• Vaccination does not protect against non-HAV hepatitis forms

What is Hepatitis B?

Hepatitis B is a blood-borne viral infection that can affect the liver. It is transmitted through blood and body fluids, including sexual contact and mother-to-child transmission at birth. Unlike Hepatitis A, HBV infection can become chronic in a portion of those infected.

Clinical management focuses on monitoring liver function and disease progression under a clinician's care. Vaccination provides strong protection, and people at risk should discuss vaccination timing and follow-up testing with a healthcare professional or insurer.

Advantages of Hepatitis B
