What is Hepatitis A?
Hepatitis A is a viral infection that causes liver inflammation. It is mainly caused by transmission through the fecal-oral route: when contaminated food or water is ingested, or through close contact with a person carrying the virus.
Hepatitis A is a very contagious virus, especially in conditions of poor sanitation. Even in developed regions, outbreaks can happen in restaurants, schools, and communities.
Common symptoms include:
- Fever
- Fatigue
- Nausea and vomiting
- Abdominal pain
- Jaundice (yellowing of the skin and eyes)
- Dark Urine
- Loss of appetite
Symptoms can linger for weeks or even months, although most people eventually recover. For this reason, vaccination is a crucial preventive measure.
How Does the Hepatitis A Vaccination Work?
The hepatitis A vaccine is made from inactivated (killed) virus, which cannot cause the infection itself. Rather, it stimulates the immune system to produce antibodies that protect you if you are exposed to the real virus in the future.
The vaccine is administered in two doses:
- First dose - provides initial protection.
- The second dose, 6–12 months later: long-term immunity
After both doses have been administered, protection generally extends to at least 20 years and, in many instances, for life.
Who Should Receive the Hepatitis A Vaccine?
Due to its extreme safety and effectiveness profile, the vaccine is indicated for a diverse range of people. You should therefore consider vaccination if you belong to any of the categories listed below:
1. Children
The vaccine is indicated for all children beginning at 12–23 months of age. Catch-up vaccination is recommended for older children who missed the vaccination.
2. International Travelers
People traveling to countries with moderate to high levels of Hepatitis A, such as parts of Asia, Africa, South America, and Eastern Europe, should receive the vaccine at least 2 weeks in advance.
3. Food Industry Workers
Chefs, restaurant staff, and food handlers are at a higher risk due to potential exposure to contaminated surfaces and ingredients.
4. Individuals Suffering from Chronic Liver Disease
Severe complications from Hepatitis A are more likely to occur in those who have existing liver disease.
5. Users of Recreational Drugs
Both injectable and non-injectable drug users carry an increased risk of exposure.
6. Contacts of Confirmed Cases
Household members or caregivers should be vaccinated right away to prevent the spread.
7. Whoever Would Be Saved
Even if you are not a high-risk individual, the vaccine is a smart preventive measure for long-term health.
Benefits of the Hepatitis A Vaccine
Vaccination can have several important advantages:
Prevents a Highly Contagious Illness
Hepatitis A spreads rapidly in populated areas and through contaminated food. Vaccination significantly reduces your risk of acquiring the virus.
Reduces the Risk of Severe Liver Damage
While rare, Hepatitis A can cause acute liver failure, especially among older adults and those with pre-existing liver diseases.
Protects Your Loved Ones
Getting vaccinated helps prevent the spread of the virus to family members, coworkers, and the community.
Essential for Safe Travel
The vaccine serves as one of the most recommended preventive steps among global travelers, who want to be at ease while venturing into new places.
Long-Lasting Immunity
Once vaccinated with two doses, you will have decades of strong protection.
Vaccine Schedule and Dosage
The hepatitis A vaccination in New York is simple:
- Dose 1: First administration in the upper arm
- Dose 2: Administer the second dose 6 to 12 months later
If you start the series late or miss a dose, you don't need to restart; simply get the follow-up dose as soon as possible.
How Effective Is the Hepatitis A Vaccine?
The vaccine is very effective:
- 95% effective after 1st dose
- Nearly 100% effective after 2nd dose
- Due to this vaccine's high effectiveness, Hepatitis A is among the most preventable liver infections in the world.
Why Are Hepatitis A Vaccines Important Today?
With global travel on the rise, frequent eating out, and endemic outbreaks in various regions, vaccination is crucial to public health. Vaccination prevents unnecessary illness, protects vulnerable populations, and helps stop the virus from circulating in communities.
By getting vaccinated, you will be investing in your long-term health and helping to keep your liver protected from a completely preventable disease.
