How do Hepatitis A Vaccinations Protect You?
News June 25, 2019 | CanadaOnlineHealth
If you’re a traveler you may have heard that you need to be vaccinated to protect yourself from Hepatitis A, also known as the hepatitis A virus (HAV). Hepatitis A is rarely fatal and does not cause chronic liver disease.
How is Hepatitis A Transmitted?
Hepatitis A is transmitted by coming in contact with another person who has the virus or by eating or drinking contaminated food and/or water contaminated by the faeces of an infected person. Poor sanitary conditions and bad hygiene are often the main risk factors for catching the virus. The hepatitis A virus is so hearty, it can even survive modern food-production processes that are used to kill or control bacterial pathogens.
Is Hepatitis A Dangerous?
According to the World Health Organization most people fully recover from hepatitis A. Still, there are some who contract HAV and die from what is called fulminant hepatitis (acute liver failure). Those infected may take weeks to return to a normal healthy lifestyle.
What are the symptoms of hepatitis A?
When HAV is transmitted there is a 14-28 day incubation period before symptoms occur. Symptoms may include:
- Fever
- Loss of appetite
- Diarrhea
- Nausea
- Upset stomach
- Jaundice
- Dark colored urine
Vaccinations and Prevention of Hepatitis A
The number one way to prevent the spread of hepatitis A is hygiene. Clean and safe drinking water, proper disposal of trash, hand washing and a clean environment in which to live can help stop the spread of HAV.
There are several injectable inactivated hepatitis A vaccines available. Virtually 100% of all people who get the vaccine will have protective levels of antibodies to the virus within 30 days of a vaccination. The World Health Organization states that manufacturers of the vaccines will recommend two doses for long-term protection.
The most common prescription vaccine injections are Havrix and Vaqta. Neither contains the live virus. They work by stimulating the body to create antibodies that will fight and kill the virus. Speak to your doctor about these vaccinations.
