Who Should Obtain The Hepatitis A Vaccine
Hepatitis A vaccine is recommended for the following persons:
- Travelers to areas with increased rates of hepatitis A
- Men who have sex with men
- Injecting and non-injecting drug users
- Persons with clotting-factor disorders
- Persons with chronic liver disease
- All children aged 12-23 months children not fully vaccinated by age two
The hepatitis A vaccine may also be used in certain outbreak situations where ongoing transmission is occurring. Although studies of certain occupational groups have not shown an increased risk, such people may consider vaccination if they wish to further reduce their risk or are in communities where ongoing outbreaks are occurring.
Will My Immunization Be Recorded
Your immunization records are registered in a computerized network known as the Immunization Records and Yellow Cards. While this one is specific to Ontario, each province has their own.
They can use information obtained in these databases to:
- Maintain immunization data
- Inform you whether or when you or your family members need an immunization
- Track how well vaccinations perform to prevent vaccine-preventable infections
You can also share your immunization history with health care providers for the provision of social health services to aid with assessment and treatment and monitor the spread of infectious illnesses.
Who Is At Risk For Infection
Anyone who is not immune to hepatitis A can get hepatitis A infection. Food-borne outbreaks occur sporadically throughout the USA. Certain groups of people do have a higher risk of developing HAV infection and should be vaccinated:
- Persons experiencing homelessness
- People who eat raw or under-cooked shellfish

How Common Is Hepatitis A
In the United States, hepatitis A has become relatively uncommon. After the hepatitis A vaccine became available in 1995, the rate of hepatitis A infections declined by 95 percent in the United States. The number of reported cases of hepatitis A fell to 1,239 in 2014, the lowest yearly number of cases reported since the disease could be tracked.1 However, the number of reported cases increased to 3,366 in 2017, almost 3 times higher, mostly due to outbreaks among people who use drugs and people experiencing homelessness.1 Early reports suggest that the numbers of cases and outbreaks of hepatitis A increased further during 2018 and continue at these higher rates in 2019.2
Hepatitis A is more common in developing countries where sanitation is poor and access to clean water is limited. Hepatitis A is more common in parts of Africa, Asia, Central and South America, and Eastern Europe than it is in the United States.
How Do I Know If I Have Hepatitis C Virus
Diagnosis of hepatitis C virus requires a blood test your doctor can order. Other blood tests can determine which subtype of HCV you have to better target your drug treatment, if needed. Your doctor will also want to know your viral load . In some patients, a liver biopsy is required to determine the level of damage.
Symptoms of chronic HCV may not appear for 2 to 3 decades after infection, so the disease may develop silently in your body for many years. This is the reason you should be tested for HCV infection, to start treatment if needed and to help protect your liver from damage.
The US Centers for Disease Control and Prevention recommends anyone 18 years or older be tested for hepatitis C virus at least once in their lifetime. Women should be tested for hepatitis C testing during each pregnancy. Some high risk groups may need more frequent testing, such as people who share drug preparation equipment and those on hemodialysis.

However, if an infant aged 6-11 months will be traveling to a country with a significant number of people with hepatitis A, the child should get one dose before leaving the U.S. The child should then get 2 doses separated by 6 to 18 months when the child is between 12 months and 23 months.

If this occurs, you will be hospitalized. Even in cases of liver failure, a full recovery is likely. Very rarely is a liver transplant required.
