The hepatitis A virus (HAV)
causes fever, nausea, vomiting, and jaundice, and can lead to community-wide epidemics.
Childcare centers are a common site of outbreaks.
HAV Immunization Schedule
The vaccine is recommended for children 12–23 months old, followed by a second
dose 6–18 months later.
The HAV vaccine also is recommended for older kids and adults who are at high risk
for the disease. This includes people who live in, travel to, or adopt children from
locations with high rates of HAV; people with clotting disorders; and people with
chronic liver disease. It also can be given to anyone who wants immunity to the disease.
The HAV vaccine also is useful for staff of childcare facilities or schools where
they may be at risk of exposure. If you plan to travel, talk to your doctor in advance
so you and your family have time to get any needed immunizations.
Why Is the HAV Vaccine Recommended?
Besides protecting the individual child, vaccination against HAV can help prevent
epidemics. Some infected kids do not have any symptoms, but can still spread the virus
to others. Having many young kids vaccinated against HAV can limit the spread of the
disease in a community.
Possible Risks of the HAV Vaccine
Side effects are usually mild fever; and tenderness, swelling, and redness at the
site of the injection. Allergic reactions to the vaccine are rare.
When to Delay or Avoid HAV Immunization
The HAV vaccine is not recommended if your child:
is currently sick, although simple colds or other minor illnesses should not
had a severe allergic reaction to the first dose of hepatitis A vaccine or has
a latex allergy
Caring for Your Child After HAV Immunization
Your child may have fever, soreness, and some swelling and redness in the area
where the shot was given. For pain and fever, check with your doctor to see if you
can give either acetaminophenoribuprofen,
and to find out the appropriate dose.
When Should I Call the Doctor?
Call if you aren't sure if the vaccine should be postponed or avoided.
Call if there are problems after the immunization.
