Question 1

Question 2

Can hepatitis A be prevented with a vaccine?

Accepted Answer

Yes, the hepatitis A vaccine is highly effective at preventing infection. It is typically given in two doses, six months apart. The vaccine is recommended for children, travelers to certain countries, people with chronic liver disease, and others at increased risk.

Question 3

Are hepatitis A and B vaccines given together?

Accepted Answer

Yes, there is a combination vaccine called Twinrix that protects against both hepatitis A and hepatitis B. It’s often used for adults who need protection from both viruses, especially before travel or for occupational health purposes.

Question 4

How long does the hepatitis A vaccine last?

Accepted Answer

After receiving the full two-dose series, protection from hepatitis A is believed to last for at least 20 years or more-possibly even for life. Booster doses are generally not needed for healthy individuals who completed the series.

Question 5

What are the symptoms of hepatitis A?

Accepted Answer

Common symptoms include fatigue, nausea, vomiting, abdominal pain, dark urine, light-colored stools, and yellowing of the skin or eyes (jaundice). Some people, especially children, may have mild symptoms or none at all.

Question 6

Can hepatitis A be asymptomatic or go away on its own?

Accepted Answer

Yes, hepatitis A is usually a self-limiting infection, especially in children who may have no symptoms. Most people recover completely without chronic liver damage.

Question 7

Can hepatitis A cause serious liver damage or complications?

Accepted Answer

While most people recover without lasting problems, hepatitis A can occasionally lead to severe liver inflammation or acute liver failure, especially in older adults or people with preexisting liver conditions. Early detection and rest are important for recovery.

Question 8

When is a person with hepatitis A considered contagious?

Accepted Answer

A person is most contagious 1 to 2 weeks before symptoms appear, and remains contagious for about a week after the onset of symptoms. This is why hepatitis A can spread easily before someone even knows they’re infected.

Question 9

Who should get the hepatitis A vaccine?

Accepted Answer

The CDC recommends the vaccine for: All children at age 12–23 months | Travelers to countries with higher hepatitis A rates | People with chronic liver disease | Men who have sex with men | People who use injection or non-injection drugs | Anyone seeking long-term protection from hepatitis A

Question 10

How is hepatitis A different from other types of hepatitis?

Accepted Answer

Hepatitis A causes acute infection only, meaning it does not become chronic. In contrast, hepatitis B and C can lead to long-term liver disease, including cirrhosis or liver cancer. Also, hepatitis A spreads primarily through contaminated food or water, while B and C spread mostly through blood or body fluids.
