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. The virus is 50 to times more contagious than HIV and can survive outside the body for at least seven days, making it much more infectious then most infectious diseases.
Nobody is immune to the first infection, and once contracted, it can lead to chronic illness and, in extreme cases, even death.

Symptoms of Hepatitis A Not all hepatitis A-infected persons will experience symptoms. Typical signs of critical hepatitis A include the following: Fatigue Nausea and vomiting Abdominal discomfort Jaundice Dark urine Low fever Loss of appetite The older you are at the point of exposure, the higher the degree of sickness.
Avoiding Getting Hepatitis A There is a secure and robust vaccination that will keep you from catching hepatitis A called Twinrix. Take these extra safety measures as well: Wash your hands regularly and thoroughly, particularly after using the bathroom, cooking food and eating Avoid foods that are raw or not cooked If you are travelling to high hepatitis A countries: Drink filtered or boiling water and use it to brush your teeth Do not use ice unless made with bottled water Avoid eating salads.
Avoid street food vendors 2. Symptoms of Hepatitis B What happens to you after you develop hepatitis B depends mostly on the age at which you first get sick and how well the immune system deals with the infection. If you are afflicted as an adult, you will have a short illness of mild to medium symptoms, such as: jaundice dark urine fatigue abdominal discomfort loss of appetite Children subjected to this infection before the age of seven years show no signs or effects at all.
Avoiding Infection of Hepatitis B There is a reliable and successful vaccination called Twinrix that will keep you from contracting hepatitis B. Other measures to protect yourself and your family members include: Adopting safe sexual activities Avoid sharing razors, nail clippers, toothbrushes etc If you are pregnant, make sure that you get tested for hepatitis B Avoid tattooing, piercing, pedicures and manicures unless safety precautions are in place 3.
Typically, you tend to feel healthy when you have jaundice, even though you keep looking worse. In hepatitis B, the jaundice stage is about two weeks. What Is Twinrix? Twinrix is the only combination hepatitis A and B vaccine available.
Who Should Receive Twinrix? In specific, vaccination against hepatitis A is suggested for: Travellers to countries or areas with a risk for hepatitis A The Canadian armed forces, emergency organization, or any other organization likely to be sent at short notice to high-risk areas for hepatitis A Zoo workers, veterinarians, and researchers People diagnosed with liver disease Hemophiliacs Hepatitis B vaccination is prescribed for those who: Travellers to countries or areas with a risk for hepatitis B areas also shown in the link above Nurses, including medical students Prisoner workers and prisoners People in contact with someone with hepatitis B People who use medication through injections Hemophiliacs Hemodialysis patients Immunodeficient people People infected with HIV Immigrants and students coming to Canada How Does One Administer Twinrix?
How Does Twinrix Work? Vaccination is the only method to avoid contamination of Hepatitis A and B. What Does Twinrix Contain? How Effective Is Twinrix? How Long Does Twinrix Last? Will My Immunization Be Recorded? Twinrix Back to top Could you please provide more information about Twinrix the combination hepatitis A and B vaccine and the two schedules for its use? The vaccine contains EL.
In the U. It can be administered to people who are at risk for both hepatitis A and hepatitis B, such as certain international travelers, people with HIV infection, people with chronic liver disease not caused by hepatitis B, men who have sex with men, illegal drug users, or to people who simply want to be immune to both diseases. Primary immunization consists of 3 doses given intramuscularly on a 0, 1, and 6 month schedule. In , the FDA also approved a 4-dose schedule for Twinrix. The 4-dose schedule could benefit individuals needing rapid protection from hepatitis A and hepatitis B, such as people traveling to high-prevalence areas imminently.
Twinrix cannot be used for postexposure prophylaxis. I have seen adults who have had 1 or 2 doses of Twinrix, but we only carry single-antigen vaccine in our practice. How should we complete their vaccination series with single-antigen vaccines? Twinrix is licensed as a 3-dose series for people age 18 years and older. If Twinrix is not available or if you choose not to use Twinrix to complete the Twinrix series, you should do the following: If 1 dose of Twinrix was given, complete the series with 2 adult doses of hepatitis B vaccine and 2 adult doses of hepatitis A vaccine.
If 2 doses of Twinrix were given, complete the schedule with 1 adult dose of hepatitis A vaccine and 1 adult dose of hepatitis B vaccine. Another way to consider this is as follows: A dose of Twinrix contains a standard adult dose of hepatitis B vaccine and a pediatric dose of hepatitis A vaccine.
Thus, a dose of Twinrix can be substituted for any dose of the hepatitis B series but not for any dose of the hepatitis A series. We're thinking of using Twinrix and we're wondering whether we can use it for doses 1 and 3 only and use single antigen hepatitis B vaccine for dose 2? For this reason, 3 doses of Twinrix must comprise the series. In addition, the Food and Drug Administration requires that the process used to produce IG include a viral inactivation step or that final products test negative for HCV-RNA by polymerase chain reaction.
Anti-HAV concentrations differ among IG lots, and decreasing concentrations have been observed over the past 30 years, probably because of the decreasing prevalence of previous HAV infection among plasma donors.
How does immune globulin IG work? IG provides protection against HAV infection through passive transfer of antibody. Depending on the IG dosage, protection lasts from 1 to 2 months.
When administered for preexposure prophylaxis, a dose of 0. If longer term protection is required and vaccination is contraindicated, a dose of 0. For postexposure prophylaxis, the recommended dosage is 0. There is no maximum dosage of IG for hepatitis A prophylaxis. How is IG packaged and how is IG administered? Intramuscular IG is available in single-use vials 2 mL and 10 mL. It should be administered intramuscularly, preferably in the anterolateral aspects of the upper thigh and the deltoid muscle of the upper arm.
Do not use the gluteal region as an injection site because of the risk of injury to the sciatic nerve. Does IG cause adverse events? Anaphylaxis has been reported after repeated administration to people with known immunoglobulin A IgA deficiency; thus, IG should not be administered to these people.
IG products including GamaSTAN have been associated with the formation of blood clots thrombosis after administration, particularly if the patient has other risk factors for thrombosis. Patients should be counseled about this risk. Can pregnant or lactating women receive IG? Pregnancy or lactation is not a contraindication to IG administration if clearly needed.
She's scheduled for her month-old well-child visit. Will this affect her vaccination schedule? IG may be given any time before or after inactivated vaccines. However, the antibodies in IG may interfere with the effectiveness of certain live-virus vaccines, such as measles, mumps, and rubella MMR and varicella vaccines. Please see details of the recommendations for the use of IG for the prevention of hepatitis A provided in Table 4 page 19 and Appendices A and B of the ACIP recommendations for the prevention of hepatitis A infection: www.
Hepatitis A vaccination is recommended for people age 6 months or older who are traveling to or working in an area of the world at intermediate or high risk of hepatitis A transmission. What are the recommendations for vaccination of travelers to protect them from hepatitis A virus HAV infection? For details on preexposure protection of international travelers age 12 months and older, refer to Appendix A on page 35 of the current ACIP recommendations for the prevention of hepatitis A: www.
Healthy people age 12 months through 40 years who are planning travel to an area with high or intermediate HAV endemicity and have not received HepA vaccine should receive a single dose of HepA vaccine as soon as travel is considered and should complete the 2-does series according to the routine schedule. People with chronic liver disease as well as adults older than 40 years of age, immunocompromised persons, and persons with other chronic medical conditions planning to depart to an area with high or intermediate HAV endemicity in less than 2 weeks should receive the initial dose of HepA vaccine, and may also simultaneously be administered IG at a separate anatomic injection site for example in separate limbs.
ACIP revised its recommendations for preexposure hepatitis A vaccination for travelers in to include vaccination of infants 6 through 11 months of age. All infants of this age traveling internationally should be given a dose of measles, mumps, rubella vaccine MMR before travel.
The routine 2-dose HepA and MMR vaccination series should be initiated at age 12 months according to the routine, age-appropriate vaccination schedule. Infants younger than 6 months and travelers who elect not to receive vaccine or for whom vaccine is contraindicated should receive a single 0. If travel is for more than 1 month, a dose of 0. Can Twinrix be used for people planning international travel? If time allows, use the standard Twinrix schedule of 3 doses given intramuscularly on a 0, 1, and 6 month schedule.
If travel is imminent the accelerated 4-dose Twinrix schedule can be used, which is 3 doses given on days 0, 7, and days and a booster dose at 12 months. We have an adult patient who received the correct pediatric series of HepA vaccine as a teenager and is now traveling abroad. Does the patient need an adult booster?
There is no recommendation for a booster dose of HepA if a patient has completed the 2-dose series at any age. Is it really necessary to vaccinate travelers to Latin America who will be staying in 4-star hotels?
Data have shown that people acquire HAV infection even in such places as 4-star hotels located in Latin America. If a traveler received the first dose of HepA vaccine more than one year ago and needs to travel abroad imminently, will the traveler need IG in addition to dose 2 prior to leaving?
Just give the final dose of HepA vaccine prior to travel. Since IG protects against HAV infection for only 1 to 2 months, depending on the dosage given, additional IG may be needed if the infant is not yet age 6 months.
Once the child has reached six months of age, HepA vaccine should be given. ACIP recommends that all children age 1 year through 18 years should be vaccinated against hepatitis A. VFC HepA vaccine may be administered to any eligible child, including those recommended for vaccination at 6 through 11 months of age as a result of travel to an HAV-endemic area. If a person was born and grew up in a country where HAV infection is endemic e. It depends on whether that person has a history of HAV infection.
Unless there are medical records that document prior HAV infection, serologic testing for immunity positive test for total anti-HAV is the only way to determine if vaccination is necessary. For people from countries with high rates of HAV infection, such as Vietnam and Mexico, serologic testing might be done to prevent unnecessary vaccination.
The cost effectiveness of serologic testing, however, should be balanced against the possibility of delaying needed vaccination while awaiting test results. If a person has had HAV infection, should they still receive the vaccine if planning international travel? No, as long as there are medical records that document that the person was previously infected with HAV i. The vaccine or IG will not harm a person who is already immune. No serious adverse events have been attributed definitively to HepA vaccine.
Among adults, the most frequently reported side effects are soreness at the site of the injection and headache. In children, the most frequently reported side effect is soreness at the injection site. The frequency of side effects after administration of Twinrix is similar to those reported when the two single-antigen vaccines were administered. Contraindications and Precautions Back to top What contraindications and precautions should be followed when administering HepA vaccine?
Hepatitis A vaccine is contraindicated for people with a history of a severe allergic reaction to a previous dose of HepA vaccine or to a vaccine component. As with all other vaccines, there is a precaution when giving it to anyone who is moderately or severely ill. Can pregnant women receive HepA vaccine?
ACIP recommends that pregnant women at risk for HAV infection during pregnancy or at risk for a severe outcome from HAV infection should be vaccinated during pregnancy if not previously vaccinated.
For additional details, see page 20 of the current ACIP recommendations: www. Can lactating women receive HepA vaccine? HepA vaccine is an inactivated vaccine and poses no harm to the nursing infant. Can HepA vaccine be given to immunocompromised people? If any immunocompromised person has a risk factor that places them at increased risk of hepatitis A e. I have a patient on interferon for hepatitis C, but I want to give him HepA vaccine.
Is it okay to vaccinate him against hepatitis A while he is on interferon? HepA vaccine should be given to all susceptible patients with chronic liver disease. HepA vaccine is very immunogenic. The vaccine must not be frozen. Any vaccine exposed to freezing temperature should not be used. Do not use these or any other vaccines after the expiration date shown on the packaging. Any vaccine administered after its expiration date is not valid and should be repeated.
