Twinrix: The Vaccine For Hepatitis A And B
Both hepatitis A and B are identified by obtaining a blood sample, which you submit to a laboratory test. This test decides whether you have antibodies in the blood unique to those viruses. If the result is positive, you have been subjected to either hepatitis A or B.
To check whether anyone has hepatitis B, the test will see whether the individual has certain hepatitis B antigen levels.
Why It Is Used
Hepatitis B virus causes a liver infection that can lead to serious complications, including liver cancer. It is common in people throughout the world, particularly in Asia and sub-Saharan Africa.
The Canadian National Advisory Committee on Immunization recommends hepatitis B immunization for all children. Pregnant women and other adults who do not have immunity and who have a high chance of exposure should be vaccinated.
Recommended Adult Dosing Volume Of Monovalent Hepatitis B Vaccine
- Age 19 years and younger: Use 0.5 mL per dose .
- Age 20 years and older: 1.0 mL per dose .

Hepatitis B Vaccine On The Nhs
A hepatitis B-containing vaccine is provided for all babies born in the UK on or after 1 August 2017. This is given as part of the 6-in-1 vaccine.
Hospitals, GP surgeries and sexual health or GUM clinics usually provide the hepatitis B vaccination free of charge for anyone at risk of infection.
GPs are not obliged to provide the hepatitis B vaccine on the NHS if you’re not thought to be at risk.
GPs may charge for the hepatitis B vaccine if you want it as a travel vaccine, or they may refer you to a travel clinic for a private vaccination. The current cost of the vaccine is around £50 a dose.
Get The Shot And Stay Informed
The hepatitis A & B virus is silent but violent. The virus is 50 to 100 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.

Why Is The Hepb Vaccine Recommended
People who dont know they’re infected can spread the hepatitis B virus. So it cant be avoided just by being careful. That’s why health experts recommend that all babies get the vaccine right from birth.
The HepB injection usually creates long-term immunity. Most infants who get the HepB series are protected from hepatitis B infection beyond childhood, into their adult years.
Eliminating the risk of infection also decreases risk for cirrhosis of the liver, chronic liver disease, and liver cancer.
Who Should Get The Hepatitis B Vaccine
Most babies now get the HBV vaccine from their doctor as a regular part of their checkups.
Hepatitis B is really contagious. You can easily get it through unprotected sex or contact with infected blood or urine. So if youve never had the vaccine, its a good idea to talk to your doctor about getting it.

Concerns About Immunisation Side Effects
If the side effect following immunisation is unexpected, persistent or severe, or if you are worried about yourself or your child’s condition after a vaccination, see your doctor or immunisation nurse as soon as possible or go directly to a hospital.
It is important to seek medical advice if you are unwell, as this may be due to other illness, rather than because of the vaccination.
Immunisation side effects may be reported to SAEFVIC, the Victorian vaccine safety and reporting service. Discuss with your immunisation provider how to report adverse events in other states or territories.
No Booster Needed For Hepatitis B Vaccine
Vaccination Lasts for More Than 10 Years, Italian Study Shows
Oct. 13, 2005 — The hepatitis B vaccine lasts for more than 10 years, so a booster vaccine may not be necessary, Italian researchers report.
“Booster doses of vaccine do not seem necessary to ensure long-term protection,” write Alessandro Zanetti, PhD, and colleagues in The Lancet.
The CDC recommends the hepatitis B vaccine for these groups:
- All babies
- All children aged 0-18 who haven’t already been vaccinated
- People whose behavior or job puts them at high risk for hepatitis B infection
The CDC doesn’t routinely recommend hepatitis B vaccine boosters for people with healthy immune systems.

Why Do You Need A Hepatitis B Shot
Hepatitis B is a viral infection that cant be transferred person-to-person unless you have contact with an infected persons bodily fluids. Annual infection rates of HBV are going down in the United States thanks to vaccines. So you might be wondering if you or your child needs a shot to protect against hepatitis B.
How Does The Hepatitis B Vaccine Series Work
The vaccine protects you from the hepatitis B virus by getting your body’s immune system to make antibodies. Those antibodies protect you by fighting off the virus if it ever gets into your body.
Usually, the vaccine is spaced out into three different shots called a hepatitis B vaccine schedule. One month after your first shot, you get the second shot. Six months after your first shot, you get the third shot. If you miss your second or third dose, get it as soon as you remember.
The hepatitis vaccine is super effective. Its worked really well to lower the number of people who get hepatitis B every year.

Who Shouldnt Get The Vaccine
It is worth noting that individuals who had serious allergic reactions to the first dose of the vaccine should not proceed with the second and third. Also, those hypersensitive to yeast shouldnt take the vaccine. People suffering from severe acute illnesses should wait until their condition is improved.
Transmission Symptoms And Treatment
How is HBV transmitted?
HBV is transmitted through activities that involve percutaneous or mucosal contact with infectious blood or body fluids , including
- sex with an infected partner
- injection-drug use that involves sharing needles, syringes, or drug-preparation equipment
- birth to an infected mother
- contact with blood from or open sores on an infected person
- exposures to needle sticks or sharp instruments and
- sharing certain items with an infected person that can break the skin or mucous membranes , potentially resulting in exposure to blood.
How long does HBV survive outside the body?
HBV can survive outside the body and remains infectious for at least 7 days .
What should be used to clean environmental surfaces potentially contaminated with HBV?
Any blood spills should be disinfected using a 1:10 dilution of one part household bleach to 10 parts of water. Gloves should be worn when cleaning up any blood spills.
Who is at risk for HBV infection?
The following populations are at increased risk for becoming infected with HBV:
- Infants born to infected mothers
- Sex partners of infected people
- Men who have sex with men
- People who inject drugs
- Household contacts or sexual partners of known people with chronic HBV infection
- Health-care and public-safety workers at risk for occupational exposure to blood or blood-contaminated body fluids
- Hemodialysis patients

. Also know, how often do you need to be vaccinated for hepatitis B?
Answer: Hepatitis B vaccine is given as a two or three dose series, depending on the age that you receive the vaccine. In general, you only need the complete Hepatitis B vaccine series once in a lifetime. Learn more about Hepatitis B and who is eligible for the vaccines publicly funded here.
Subsequently, question is, do I need a Hep B booster? Are booster doses of the hepatitis B vaccine necessary? Booster doses are not recommended for most healthy people. Booster doses are recommended only in certain circumstances and the need for booster doses is determined by a certain blood test that looks for hepatitis B surface antibody .
Besides, is hepatitis B vaccine lifelong?
Hepatitis B is a virus that attacks the liver. It can cause serious disease, including permanent liver damage , and is also the main cause of liver cancer. The hepatitis B vaccine provides immunity for at least 10 years and likely for a lifetime when completing the full series.
How long is HBV vaccine good for?
Studies indicate that immunologic memory remains intact for at least 30 years among healthy people who initiated hepatitis B vaccination at > 6 months of age. The vaccine confers long-term protection against clinical illness and chronic hepatitis B virus infection.
Hepatitis B Vaccine Complications
Adverse reactions to the vaccine are few and usually mild:
- There may be some soreness and erythema around the site. These are the most common reactions.
- Fatigue, malaise and influenza-like symptoms are rare.
- Rare associations with a Guillain-Barré-type syndrome and also multiple sclerosis have been reported but a causal relationship has not been substantiated.
HBIG is well tolerated. Reactions and side-effects are rare.

Concurrent Administration Of Vaccines
HB-containing vaccines may be administered concomitantly with other vaccines or with HBIg. Different injection sites and separate needles and syringes must be used for concurrent parenteral injections.
Refer to Timing of Vaccine Administration in Part 1 for additional information about concurrent administration of vaccines.
Immunisation Against Hepatitis B
The current Australia-wide immunisation program is necessary to protect all children from hepatitis B infection.
A full course of hepatitis B injections must be given for a child to be protected. It is recommended that this course begins within 24 hours of birth with a vaccine against hepatitis B alone. Further doses are routinely given at 2 months, 4 months and 6 months, as a combination vaccine.
Immunisation is the best protection against hepatitis B infection. In Victoria a free hepatitis B vaccine is available for a number of groups at high risk, including men who have sex with men, and people living with HIV.
The adult course involves 3 doses of the vaccine over 6 months and gives protection to about 95 per cent of people. Once you have had the 3 doses, you can have a blood test to see if you are protected.

Who Should Get The Vaccine
The Hepatitis B vaccine is recommended for all infants and children aged between 0 and 18. In the case of infants, it is recommended to take the vaccine at birth, while still in hospital. In cases where the vaccine was omitted at birth, its important to complete the 3-shot series as soon as possible. Adolescents and adults who havent received the vaccine on time are also recommended to complete the vaccination as soon as they can.
Members of the following at-risk groups should take special care to get vaccinated: healthcare workers, people in treatment for another STD, the partners and household members of individuals with HIV/AIDS, prison inmates, intravenous drug users , sexually active people who are not in exclusive relationships, men who engage in sex with other men, residents and staff of homes and facilities that care for the developmentally challenged, and people with serious kidney diseases .
Some US populations have a substantially higher rate of HBV infections. This includes Pacific Islanders, Alaska Natives, as well as immigrants and refugees from endangered territories and countries. People who belong to these endangered groups are highly advised to take the vaccine.
Neonatal Hepatitis B Screening And Immunisation
Babies born to mothers infected with hepatitis B have a high risk of acquiring infection, which can be prevented by vaccination at birth. Therefore all women in the UK are screened during each pregnancy for hepatitis B. If a mother not previously booked for antenatal care presents in labour, she should have urgent hepatitis B screening, so that if needed the vaccine can be given to the infant within 24 hours of birth. Those women who are HbeAg-positive are particularly infectious.

Hepatitis B Vaccine Schedule
- Dosage depends on age and brand. The manufacturer’s guidance should be followed.
- Injections are given intramuscularly in the upper arm or anterolateral thigh. It should not be given into the buttock.
- The standard course of immunisation involves three injections at 0, 1 and 6 months.
- An accelerated course of 0, 1 and 2 months is possible – also for combined hepatitis A and B vaccines.
- Adults who need protection very quickly can have a schedule of 0, 7 and 21 days. Adults and children considered at very high risk should also have an accelerated schedule. After an accelerated course, a booster at one year is recommended.
- Accelerated courses may also be best for drug abusers, as they are notoriously difficult to get to complete a course.
The duration of protection provided by the hepatitis B vaccine is still unknown but is believed to be at least 20 years.
The current UK recommendation is that those who have received a primary course of immunisation, including children vaccinated according to the routine childhood schedule and individuals at high risk of exposure, do not require a reinforcing dose of HepB-containing vaccine, except in the following categories:
