Safe
and effective vaccines are now available for protection against hepatitis
B, a serious liver infection that can result in cirrhosis and liver
cancer.
The
Centers for Disease Control and the American Academy of Pediatrics recommend
that all newborns, infants and children, especially sexually active
teenagers be vaccinated against hepatitis B.
Vaccination
is also recommended for individuals at high risk of being infected with
the hepatitis B virus (HBV). These include:
- Health
care workers, including doctors, dentists, nurses, blood and lab technicians;
- Emergency
workers - including paramedics, fire fighters and police;
- Hemodialysis
patients;
- Military
personnel;
- Morticians
and embalmers;
- Patients
and staff of institutions for the mentally handicapped, inmates of
long-term correctional institutions;
- Ethnic
groups with a high rate of hepatitis B including Chinese, Koreans,
Indochinese, Filipinos, Alaskan Eskimos, Haitians, and American Indians;
- People
with multiple sexual partners;
- Intravenous
drug users;
- Recipients
of certain blood products;
- Household
contacts and sex partners of hepatitis B carriers;
- International
travelers
Those
who are already infected will not benefit from vaccination. However,
infants born of mothers who are carriers of the hepatitis B virus can
be protected. A simple blood test can determine whether someone is a
hepatitis B carrier.
Immunization requires three doses of vaccine according to the following
schedule:
- 1st
dose: For infants born to infected mothers - within 12 hours.
For infants born to mothers who test negative - within one to
two months following delivery.
- 2nd
dose: 1 month later.
- 3rd
dose: 6 months after the first dose.
Administration
is by intramuscular injection in the thigh or upper arm.
Hepatitis
B is caused by a virus and is spread through blood, other body fluids
and contaminated needles.
In
the United States, there are about 1,000,000 carriers, who have no symptoms
but can pass the infection on to others, and an estimated 300,000 new
cases a year.
A
significant number of people with hepatitis B have no symptoms. Others
may have flu-like symptoms: fever, fatigue, muscle or joint pain, appetite
loss, nausea and vomiting. Twenty-five to thirty-five percent have symptoms
such as jaundice, a yellowing of the skin and eyes, that indicates liver
damage.
Five
to ten percent of hepatitis B young adult victims become chronic carriers,
often without knowing it. Nine of ten infants infected become chronic
carriers. They are at increased risk of developing cirrhosis and liver
cancer.
The
vaccines provide immunization in about 90 percent of recipients.

TEST
RESULTS AND INDICATIONS FOR VACCINATION
Checking
To See If The Patient Needs Hepatitis B Vaccine: One must use a combination
of two tests to truly determine if a patient is a carrier, already immune
or still susceptible to the hepatitis B virus. The physician can use
HBsAg and Anti-HBc or HBsAg and Anti-HBs.
HBsAg
Anti-HBc |
Positive
Positive
|
The
patient is a carrier.
|
DOES
NOT NEED THE HEPATITIS B VACCINE. |
HBsAg
Anti-HBc |
Negative
Positive
|
The
patient has been exposed and has probably developed natural immunity.
Alternatively, he may be an individual with an isolated Anti-HBc
result (HBsAg negative, Anti-HBc positive and Anti-HBs negative)
|
DOES
NOT NEED THE VACCINE. |
HBsAg
Anti-HBc |
Negative
Negative
|
The
patient is susceptible to hepatitis B.
|
GIVE
THE FULL VACCINE PROTOCOL. |
HBsAg
Anti-HBc |
Positive
Negative
|
The
patient is infected with hepatitis B and is probably a carrier.
|
DOES
NOT NEED THE HEPATITIS B VACCINE. |
HBsAg
Anti-HBc |
Negative
Positive |
The
patient has already been exposed and has developed natural immunity
or has been successfully vaccinated. |
DOES
NOT NEED THE VACCINE. |
HBsAg
Anti-HBc |
Negative
Negative
|
The
patient is susceptible.
|
SHOULD
RECEIVE THE VACCINE. |
