Epinephrine injection and other agents used in the treatment of severe anaphylaxis should be immediately available in the event of a serious allergic reaction to the vaccine. Patients with thrombocytopenia, vitamin K deficiency, a coagulopathy e. The vaccine should be given only if the potential benefits clearly outweigh the risk of administration.
If the decision is made to administer the vaccine in such persons, the vaccine should be given with caution. Steps should be taken to avoid the risk of bleeding and hematoma formation following intramuscular administration. The decision to administer or to delay vaccination with the hepatitis A vaccine, inactivated because of current or recent febrile illness depends on the severity of symptoms and on the etiology of the disease.
The Advisory Committee on Immunization Practices recommends that vaccinations be delayed during the course of a moderate or severe acute febrile illness and administered after the acute phase of illness has resolved, unless the patient is at immediate risk of hepatitis A infection.
Use caution when administering the vaccine to patients with severely compromised cardiopulmonary status. All vaccines can be administered to persons with minor illnesses such as diarrhea, mild upper-respiratory infection with or without low-grade fever, or other low-grade febrile illness. Persons with moderate or severe febrile illness should be vaccinated as soon as they have recovered from the acute phase of the illness. Patients with immunosuppression may respond to hepatitis A vaccine, inactivated with lower antibody titers than non-immunosuppressed patients.
Immunosuppressed persons may include patients with human immunodeficiency virus HIV infection; severe combined immunodeficiency SCID ; hypogammaglobulinemia; agammaglobulinemia; altered immune states due to generalized neoplastic disease; or an immune system compromised by radiation therapy or drug therapy e.
Patients vaccinated with hepatitis A vaccine, inactivated within 2 weeks before starting immunosuppressive therapy or while receiving immunosuppressive therapy should be considered unvaccinated and should be revaccinated at least 3 months after therapy is discontinued if immune competence has been restored.
Lower antibody titers are particularly a concern in patients with human immunodeficiency virus HIV infection, as the CD4 count at the time of vaccination has been associated with reduced development of anti-HAV IgG antibodies; however, data suggest that patients will respond to vaccination after immunologic reconstitution with highly active antiretroviral therapy.
In a study, response to vaccination was directly related to the CD4 cell count at vaccination: the higher the CD4 cell count, the higher the likelihood of detectable anti-HAV IgG. The relationship between the CD4 count and vaccination response was independent of the nadir CD4 cell count and viral load. According to the guidelines for the prevention and treatment of opportunistic infections in HIV-infected adolescents and adults, assess the IgG antibody response to the hepatitis A vaccine, inactivated one month after vaccination, and revaccinate nonresponders.
No adequate and well-controlled studies have been conducted with the hepatitis A vaccine, inactivated during pregnancy.
In pre- and post-licensure clinical studies and post-approval reports, pregnant women who were administered hepatitis A vaccine, inactivated had rates of miscarriage and major birth defects that were consistent with estimated background rates.
The ACIP recommends vaccination during pregnancy when the likelihood of disease exposure is high, potential infection would cause harm to mother or fetus, and when the vaccine is unlikely to cause harm.
There is no information regarding the presence of hepatitis A vaccine, inactivated in human milk, its effects on the breast-fed infant, or its effects on milk production. Consider the developmental and health benefits of breast-feeding along with the mother's clinical need for hepatitis A vaccine, inactivated and any potential adverse effects on the breast-fed child from hepatitis A vaccine, inactivated or the underlying maternal condition.
Hepatitis A vaccine, inactivated is only indicated for intramuscular administration; do not give via intravenous administration, subcutaneous administration, or intradermal administration. Incorrect administration may result in inadequate immunity. Patients with chronic hepatic disease may have a lower antibody response to hepatitis A vaccine, inactivated. One month after a booster dose given 6 months after dose 1, seroconversion rates were similar among groups.
The relationship between these data and the duration of protective immunity is unknown. Ocrelizumab: Moderate Administer all non-live vaccines at least 2 weeks before ocrelizumab initiation, whenever possible. Ocrelizumab may interfere with the effectiveness of non-live virus vaccines.
Attenuated antibody responses to tetanus toxoid-containing vaccine, pneumococcal polysaccharide and pneumococcal conjugate vaccines, and seasonal influenza vaccine were observed in patients exposed to ocrelizumab at the time of vaccination during an open-label study. Infants born to mothers exposed to ocrelizumab during pregnancy may receive non-live vaccines as indicated before B-cell recovery; however, consider assessing the immune response to the vaccine.
ACIP recommends that patients receiving any vaccination during immunosuppressive therapy or in the 2 weeks prior to starting therapy should be considered unimmunized and should be revaccinated a minimum of 3 months after discontinuation of therapy.
Passive immunoprophylaxis with immune globulins may be indicated for immunocompromised persons instead of, or in addition to, vaccination.
Injection of hepatitis A vaccine produces antibodies that confer protection against hepatitis A infection. Stimulation of specific antibodies takes place without producing any disease symptoms.
During the course of natural infection with the hepatitis A virus, the initial antibody response is predominantly of the IgM class. This response lasts for several months, but during convalescence antibodies of the IgG class become dominant.
The IgG antibodies remain detectable indefinitely. Two years after immunization with hepatitis A vaccine IgG levels remained relatively high in the serum of immunized patients.
The duration of protection from a course of hepatitis A vaccine is as yet unknown. Long term follow-up studies will determine the necessity for booster doses of HAV. Hepatitis A vaccine, inactivated is administered intramuscularly.
Rapid seroconversion from a single-dose can provide protection against hepatitis A for at least 12 months. Increasing the dose of viral antigen directly affects the speed at which seroconversion occurs. However, a primary response to the vaccine can be expected 8 to 10 days after administration. To maintain the highest antibody titers a booster dose is recommended between 6 and 18 months after the initial dose.
The response to this booster dose is vigorous and increases the protection time against hepatitis A. PDR Search. Required field. Your Name Your name is required.

Hepatitis A Questions and Answers for Health Professionals | Division of Viral Hepatitis | CDC
Hepatitis A is a serious liver disease. It is caused by the hepatitis A virus HAV. HAV is spread from person to person through contact with the feces stool of people who are infected, which can easily happen if someone does not wash his or her hands properly.
You can also get hepatitis A from food, water, or objects contaminated with HAV. These symptoms usually appear 2 to 6 weeks after exposure and usually last less than 2 months, although some people can be ill for as long as 6 months. If you have hepatitis A you may be too ill to work. Children often do not have symptoms, but most adults do. You can spread HAV without having symptoms. Hepatitis A can cause liver failure and death, although this is rare and occurs more commonly in persons 50 years of age or older and persons with other liver diseases, such as hepatitis B or C.
Hepatitis A vaccine can prevent hepatitis A. Hepatitis A vaccines were recommended in the United States beginning in Since then, the number of cases reported each year in the U. Top of Page. Hepatitis A vaccine is an inactivated killed vaccine. You will need 2 doses for long-lasting protection. These doses should be given at least 6 months apart. Children are routinely vaccinated between their first and second birthdays 12 through 23 months of age. Older children and adolescents can get the vaccine after 23 months.
Adults who have not been vaccinated previously and want to be protected against hepatitis A can also get the vaccine.
With any medicine, including vaccines, there is a chance of side effects. These are usually mild and go away on their own, but serious reactions are also possible. As with any medicine, there is a very remote chance of a vaccine causing a serious injury or death. The safety of vaccines is always being monitored. For more information, visit the vaccine safety site. Persons who believe they may have been injured by a vaccine can learn about the program and about filing a claim by calling or visiting the VICP website External.
There is a time limit to file a claim for compensation. Skip directly to site content Skip directly to page options Skip directly to A-Z link. Section Navigation. On This Page. Tell the person who is giving you the vaccine: If you have any severe, life-threatening allergies. If you ever had a life-threatening allergic reaction after a dose of hepatitis A vaccine, or have a severe allergy to any part of this vaccine, you may be advised not to get vaccinated. Ask your health care provider if you want information about vaccine components.
If you are not feeling well. If you have a mild illness, such as a cold, you can probably get the vaccine today. If you are moderately or severely ill, you should probably wait until you recover. Your doctor can advise you. Most people who get hepatitis A vaccine do not have any problems with it. Minor problems following hepatitis A vaccine include: soreness or redness where the shot was given low-grade fever headache tiredness If these problems occur, they usually begin soon after the shot and last 1 or 2 days.
Your doctor can tell you more about these reactions. Other problems that could happen after this vaccine: People sometimes faint after a medical procedure, including vaccination. Sitting or lying down for about 15 minutes can help prevent fainting, and injuries caused by a fall. Tell your provider if you feel dizzy, or have vision changes or ringing in the ears. Some people get shoulder pain that can be more severe and longer lasting than the more routine soreness that can follow injections.
This happens very rarely. Any medication can cause a severe allergic reaction. Such reactions from a vaccine are very rare, estimated at about 1 in a million doses, and would happen within a few minutes to a few hours after the vaccination.
