Guidance On Reporting Adverse Events Following Immunization

Vaccine providers are asked to report, through local public health officials, any serious or unexpected adverse event temporally related to vaccination. An unexpected AEFI is an event that is not listed in available product information but may be due to the immunization, or a change in the frequency of a known AEFI.

Refer to Reporting Adverse Events Following Immunization in Canada and Vaccine Safety and Pharmacovigilance in Part 2 for additional information about AEFI reporting.

Who Should Not Receive Hepatitis A Vaccine

There are a very few situations where the hepatitis A vaccine is not recommended. They include:

  • If you have an illness causing a high temperature. In this situation, it is best to postpone vaccination until after you have fully recovered from the illness.
  • If you have had an allergic reaction to the vaccine or to any of its components in the past.
  • One type of vaccine should not be given to anyone who is known to be allergic to eggs.
  • Children under the age of 1 year. However, the risk of hepatitis A in children under the age of 1 year is very low. The hepatitis A vaccine is not licensed for this age group.

The vaccine may be given if you are pregnant or breastfeeding and vaccination against hepatitis A is thought to be necessary.

Hepatitis A Vaccine And International Travel

Who should get the hepatitis A vaccine before traveling internationally?

All unvaccinated people, along with those who have never had hepatitis A, should be vaccinated before traveling to countries where hepatitis A is common. Travelers to urban areas, resorts, and luxury hotels in countries where hepatitis A is common are still at risk. International travelers have been infected, even though they regularly washed their hands and were careful about what they drank and ate. Those who are too young or cant get vaccinated because of a previous, life-threatening reaction to the hepatitis A vaccine or vaccine component should receive immune globulin. Travelers to other countries where hepatitis A does not commonly occur are not recommended to receive hepatitis A vaccine before travel.

How soon before travel should I get the hepatitis A vaccine?

You should get the first dose of hepatitis A vaccine as soon as you plan international travel to a country where hepatitis A is common. The vaccine will provide some protection even if you get vaccinated closer to departure. For older adults , people who are immunocompromised, and people with chronic liver disease or other chronic medical conditions the health-care provider may consider, based on several factors, giving an injection of immune globulin at the same time in different limbs.

How Does Hepatitis A Spread

Contaminated food or water is the most common source of hepatitis A infection. Contamination can happen at any point in the food growing, processing or cooking process. Travelers are at an increased risk. Take extra precautions in developing countries with poor sanitary conditions.

It is possible for the disease to spread through close contact with an infected person. This includes sex or caring for an infected person.

Vaccination is the best form of protection.

How And When Do Doctors Give Vaccines

Havrix hepatitis a vaccine

For the hepatitis A vaccine:

You should get two doses, given as shots, 6 months apart for complete protection. The virus in the vaccine is killed .

Children should get the first dose between 12 and 23 months of age. Children older than age 2 can get the first dose at their next doctorâs visit.

If you need the vaccine because of upcoming travel, get it at least 1 month before you go.

For the hepatitis B vaccine:

For long-lasting immunity, you need three to four doses, depending on which type of vaccine is used. You get them as shots.

Children should get their first dose at birth and complete the series by age 6 months. Usually, the baby would get a second dose at 1 month old and the third dose at 6 months.

Babies born to women who have hepatitis B need a shot of hep B antibodies, as well as their first hep B vaccine shot, when theyâre born. They will also need follow-up blood tests to make sure theyâre OK.

Catch-up vaccinations are recommended for children and teens who were never vaccinated or who did not get all three shots.

If you’re an adult who wants to be vaccinated, you should talk about it with your doctor or pharmacist. If you are considering both vaccines, ask your doctor about vaccines that combine hep A and B.

Interchangeability Of Hepatitis A Vaccines

Vaccine manufacturers use slightly different methods to produce the vaccines and quantify the hepatitis A virusantigen content. All monovalent hepatitis A vaccines that are given as a 2-dose course are interchangeable. See Table. Recommended doses and schedules for monovalent hepatitis A vaccines.

Schedules that mix combination hepatitis A/hepatitis B vaccines with monovalent vaccines are not routinely recommended.

An adult dose of Twinrix 720/20 contains half the hepatitis A antigen content of an adult dose of Havrix adult vaccine. These vaccines are therefore not interchangeable.

The only absolute contraindications to hepatitis A vaccines are:

  • anaphylaxis after a previous dose of any hepatitis A vaccine
  • anaphylaxis after any component of a hepatitis A vaccine

Combination hepatitis A/hepatitis B vaccines are contraindicated in people with a history of anaphylaxis to yeast.

    Hepatitis A Vaccine Needed

    Is it ok to go to major areas like San Jose, Arenal, and Manuel Antonio without Hepatitis A vaccine. We are leaving in one week and I’ve been told it is too close to departure to have the vaccine be effective. Is it dumb to risk going without the vaccine? Can you eat fruit, lettuce, non-bottle water, ice, etc.? Please advise, anyone.

    We stayed near the San Jose airport, Arenal, Mal Pais and the Osa. We did not get any special vaccines or malaria medicine for the trip.

    With the exception of Bosque del Cabo in the Osa, we were told on check-in at all of the hotels we stayed at that the water was potable. We ate fruit, salads, ice, ceviche just about everywhere but we did mainly eat at our hotels or at restaurants widely recommended

    Having said all that, however, I had a bit of the “traveler’s stomach” on the day we came home and for a day after. Nothing that couldn’t be handled with a little Immodium AD but I’m glad I’d packed some!

    Taking malaria pills depends on where you are going. Good DEET based mosquito repellent is more important for Malaria and Dengue.

    Before Taking This Medicine

    Hepatitis A and B vaccine will not protect you against infection with hepatitis C or E, or other viruses that affect the liver. It will also not protect you from hepatitis A or B if you are already infected with the virus, even if you do not yet show symptoms.

    You should not receive this vaccine if you are allergic to yeast or neomycin, or if you have ever had a life-threatening allergic reaction to any vaccine containing hepatitis A or hepatitis B.

    Before receiving this vaccine, tell the doctor if you have:

    • an allergy to latex rubber or

    • a weak immune system caused by disease, bone marrow transplant, or by using certain medicines or receiving cancer treatments.

    You can still receive a vaccine if you have a minor cold. In the case of a more severe illness with a fever or any type of infection, wait until you get better before receiving this vaccine.

    FDA pregnancy category C. Tell your doctor if you are pregnant. It is not known whether hepatitis A and B vaccine will harm an unborn baby. However, not vaccinating the mother could be harmful to the baby if the mother becomes infected with a disease that this vaccine could prevent. Your doctor will decide whether you should receive this vaccine, especially if you have a high risk of infection with hepatitis.

    If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of this vaccine on the baby.
