Hepatitis B Vaccine Drug Card

How Effective Is Prehevbrio At Preventing Hepatitis B

Fake Hepatitis B vaccines had no effect on patients – Gov’t

Most of what we know about PreHevbrios effectiveness comes from two clinical trials. These trials were called PROTECT and CONSTANT. Both studies looked to see how safe and effective PreHevbrio is. The CONSTANT study also studied manufacturing quality.

In clinical trials, a larger percentage of people who received PreHevbrio made enough antibodies to be considered protected against hepatitis B compared to those who received Engerix-B. This difference was most notable in adults 45 years and older.

Additionally, everyone who received PreHevbrio developed more antibodies against hepatitis B compared to those who received Engerix-B. And the percentage of people with protective antibody levels went down less in the PreHevbrio group after about 12 months.

No safety or manufacturing concerns were found in either study. But, like with all vaccines, many people had a few side effects.

What Are Nonviral Causes Of Hepatitis

Other things can cause hepatitis besides viruses. The most common nonviral cause of hepatitis is heavy alcohol use. Certain medications, chemicals, or supplements can also cause hepatitis. The least common type of nonviral hepatitis is autoimmune hepatitis, which results when the bodys immune system attacks the liver.

Who Should And Shouldnt Receive Prehevbrio

As mentioned, the CDC hasnt officially included PreHevbrio into its list of recommended vaccines.

But PreHevbrios labeling helps offer some preliminary insight into who should and shouldnt receive the vaccine. If youre 18 years or older, you may be eligible to get this vaccine.

But if any of the following items apply to you, PreHevbrio may not be the best choice for you:

  • Age 17 or younger

  • Have an active hepatitis B infection

  • Have an allergy to any ingredient in PreHevbrio

  • Have experienced a severe allergic reaction to another hepatitis B vaccine

Its not known how this vaccine affects women who are pregnant or nursing. This is also true for people who are receiving dialysis. For more information, talk to your healthcare provider.

Prevention Of Hepatitis A Virus Infection

Prevention of HAV infection in adults, adolescents, and children 1 year of age.

Although HAV infection may be asymptomatic or relatively mild in many patients, it can result in substantial morbidity and associated health-care costs and work loss and may be associated with fulminant hepatitis and hepatic failure. Overall HAV case-fatality rate in the US is 0.30.6%, but increases to about 2% in those 40 years of age. HAV is highly contagious . The virus is transmitted person-to-person, principally through the fecal-oral route. HAV infection remains one of the most commonly reported vaccine-preventable diseases in travelers.

USPHS Advisory Committee on Immunization Practices , AAP, and American Academy of Family Physicians recommend that all children be vaccinated against HAV infection at 1 year of age , unless contraindicated.

ACIP, AAP, AAFP, American College of Obstetricians and Gynecologists , and American College of Physicians also recommend vaccination against HAV for all previously unvaccinated children, adolescents, and adults at high risk of exposure to HAV and for any other unvaccinated individual desiring protection from HAV infection.

HepA vaccine will not prevent hepatitis caused by other infectious agents .

A controlled study demonstrated that completion of a course of immunization with 1 dose of ENGERIX-B at Month 6 following 2 doses of RECOMBIVAX HB at Months 0 and 1 produced a similar GMT to immunization with 3 doses of RECOMBIVAX HB at Months 0, 1, and 6 . Thus, ENGERIX-B can be used to complete a vaccination course initiated with RECOMBIVAX HB.8

How Does Prehevbrio Prevent Hepatitis B

PreHevbrio works by showing your body how to make antibodies against HBV. It helps protect you against hepatitis B infection if youre exposed to HBV.

Specifically, PreHevbrio teaches your body to make antibodies that can recognize three antigens found on the outside of HBV cells. These antibodies help your immune system target and kill HBV cells that have any of the antigens from PreHevbrio.

Of note, PreHevbrio should only be used to help prevent hepatitis B. Its not meant to treat hepatitis B if you already have it.

    Hepatitis B immune globulin is injected into a muscle or into a vein through an infusion pump. A healthcare professional will give you this injection.

    For prevention after exposure to contaminated blood: Hepatitis B immune globulin is usually given as soon as possible after exposure to an infected person, preferably within 7 days. A booster medication is then given 24 hours later. Your doctor may also recommend that you receive a hepatitis B vaccine when you start treatment with hepatitis B immune globulin.

    For liver transplant: Hepatitis B immune globulin is given as part of the transplant procedure, and then for several weeks or months afterward. The medication is usually given to transplant patients every day for 7 days, then every 2 weeks for the next 11 weeks, followed by monthly injections from then on.

    Efficacy And Immunogenicity In Specific Populations

    Homosexual Men

    ENGERIX-B given at 0, 1, and 6 months was evaluated in homosexual men aged 16 to 59 years. Four of 244 subjects became infected with hepatitis B during the period prior to completion of the 3-dose immunization schedule. No additional subjects became infected during the 18-month follow-up period after completion of the immunization course.

    Adults with Chronic Hepatitis C

    In a clinical trial of 67 adults aged 25 to 67 years with chronic hepatitis C, ENGERIX-B was given at 0, 1, and 6 months. Of the subjects assessed at Month 7 , 100% responded with seroprotective titers. The geometric mean antibody titer was 1,260 mIU/mL .

    Adults on Hemodialysis

    Hemodialysis patients given hepatitis B vaccines respond with lower titers, which remain at protective levels for shorter durations than in normal subjects. In a clinical trial of 56 adults who had been on hemodialysis for a mean period of 56 months, ENGERIX-B was given at 0, 1, 2, and 6 months. Two months after the fourth dose, 67% of patients had seroprotective antibody levels and the GMT among seroconverters was 93 mIU/mL.

    What Populations Are Most At Risk For Hepatitis B Infection

    Some people are more at risk of being exposed to the hepatitis B virus than others. These groups include:

    • Healthcare workers

    • Feeling tired or being fatigued

    • Yellowing of the eyes or skin

    • Dark urine

    These symptoms can appear as early as 2 weeks or as late as 4 months after you are exposed to the virus. Because so many people do not have symptoms or develop symptoms months later, they may not realize they have the hepatitis B virus and that they can spread the infection to others.

    Recommended Dose And Schedule

    Sanford Guide:Hepatitis Rx

    Persons from Birth through 19 Years

    Primary immunization for infants , children , and adolescents consists of a series of 3 doses given on a 0-, 1-, and 6-month schedule.

    Persons Aged 20 Years and Older

    Primary immunization for persons aged 20 years and older consists of a series of 3 doses given on a 0-, 1-, and 6-month schedule.

    Adults on Hemodialysis

    Primary immunization consists of a series of 4 doses given as a single 2-mL dose or two 1-mL doses on a 0-, 1-, 2-, and 6-month schedule. In hemodialysis patients, antibody response is lower than in healthy persons and protection may persist only as long as antibody levels remain above 10 mIU/mL. Therefore, the need for booster doses should be assessed by annual antibody testing. A 2-mL booster dose should be given when antibody levels decline below 10 mIU/mL.1
